Reducing the Risks: Why Fighting Dirty Air at Home Saves Lives

Air pollution is now recognised to be the greatest environmental threat to human health in the UK. A major health risk, it is more harmful than passive smoking and, according to Public Health England, is responsible for as many deaths as alcohol. Reducing exposure to air pollution is now a major government initiative, but the challenge is vast.

Evidence from the Royal College of Physicians and the World Health Organisation states that as many as 40,000 deaths each year are the result of air pollution and poor indoor air quality, with long-term exposure linked to asthma, heart and lung disease, cancer, dementia, diabetes and stroke.

Exposure to high concentrations of pollutants is harmful to our health, and the effects are cumulative, causing damage at every stage of our lives. Elderly people and those with existing health conditions like asthma and heart disease are particularly at risk from poor air quality. Episodes of high air pollution are linked to spikes in hospital admissions with respiratory problems and cardiac arrests, and to increased mortality rates. Children are also vulnerable, developing long-life health problems like asthma as a result of early exposure to air pollution. An investigation into the death of a child in London due to asthma has, for the first time, explicitly named poor air quality as the main cause. Sadly, this landmark case is likely to be the first of many. Action to protect the most vulnerable from harmful pollutants, at home, at work, at school and when travelling, is needed now.

Invisible But Deadly 

So what are the culprit gases and particles that are of most concern? The government has a statutory obligation to keep concentrations of some pollutants below a certain level. These are fine particulate matter (PM2.5), nitrogen dioxide (NO2 and NOX), non-methane Volatile Organic Compounds (NMVOCs), ammonia (NH3) and sulphur dioxide (SO2).

These pollutants come from many sources, including road traffic, industrial processes, agriculture and domestic fuel burning. Some of these pollutants react in the air, in sunlight and with each other to form other pollutants. Both NOX and VOCs react with other pollutants and in sunlight to form low level ozone. Ammonia converts to Particulate Matter after several days in the atmosphere, while sulphur dioxide combines with water to form acid rain.

Reactions between NOX, sulphur dioxide and ammonia form secondary PM. The process is fast, continuous and highly unstable. Add the influence of weather and you have a bigger problem. Day-to-day changes in weather have a great influence on air quality.  High winds can transport PM and ammonia a long way from their original source, increasing exposure in other areas. In urban areas, air pollution levels are often highest on warm, still days when dispersion is limited and sunlight causes chemical reactions.

Road transport is the largest single source of nitrogen dioxide emissions and also produces Particulate Matter, VOCs, SO2 and ozone. People living near busy roads are at greatest risk of exposure to air pollution both as they travel outside and in their homes. In fact, levels of N02 can be as high inside the home as they are at the roadside in high pollution areas.

In a recent report by the World Health Organisation which has made headline news in the British press, it was highlighted that 37 of 43 air quality zones across the UK have failed to meet EU limits on N02. These regions will have streets or larger areas that are labelled Air Quality Management Areas or AQMAs for failing to meet air quality objectives set by government. There are currently 725 in England, 45 in Wales, 43 in Scotland and 42 in Northern Ireland, so the problem is sizable and widespread.

A Disparity Between New and Existing Homes

With what is now known about the health effects of air pollution, focus has turned to mitigation techniques to keep pollutants out of the home. Technology for air filtration in new build developments is making great strides, with highly-effective carbon filter products that work as part of a ducted Mechanical Ventilation with Heat Recovery (MVHR) system.

Nuaire launched its inline IAQ-BOX system which removes up to 99.5% of NO2 and up to 85% of PM2.5. Last year, we took this concept further with the design of the first carbon filter supply air valve which is highly effective yet easier and quicker to install and maintain.

Protection for occupants in newly built homes in high pollution areas already exists and in many cases, is becoming a planning condition. But when you consider there are 27 million existing homes in the UK, compared with 170,000 new homes built each year, the disparity is clear. The industry has been waiting for a solution for the millions of existing homes that are blighted by poor air quality.

As MVHR systems with carbon filtration require ducting through the property, they are highly intrusive to install in existing homes. Many existing properties are ventilated using intermittent extract fans, which are not effective at preventing the ingress of pollutants or their removal.

Finally, A Retrofit Solution

Nuaire has developed a new technology for existing homes. The Noxmaster is a whole house ventilation system that combines a trusted technology called Positive Input Ventilation or PIV with the same high-efficiency carbon filtration as used in new-build homes.

We are currently running tests with Noxmaster at Hafodyrynys Hill, Caerphilly - the most polluted street outside of London, as named by the World Health Organisation.  A controlled test house has been monitored for a number of months to show the difference between the pollution levels at the roadside, the pollution levels in a typical property, and the greatly reduced NOX levels with the Noxmaster installed. The results are exciting.

The Noxmaster combines a powerful carbon filter with a strategy invented by Nuaire over 45 years ago, Positive Input Ventilation (PIV).  This combination removes up to 99.5% of nitrogen dioxide and other harmful pollutants generated by traffic emissions and industrial processes. It delivers clean, filtered air into the home, improving the indoor air quality to within safe levels.

The secret weapon here is activated carbon. The carbon media held inside a cartridge is microporous and has a much larger surface area than its external dimensions suggest. A spoonful of activated carbon equates to the surface of a football field. Through a process known as ‘adsorption’, the pollutants are attracted and held on the surface of the carbon, trapping them before they enter the home.

An additional benefit of the Noxmaster is the reduction in humidity levels which prevents condensation dampness, and its ability to flush out pollutants generated inside the home from the use of household products, cooking with gas and burning fuel.

Reducing Exposure Saves Lives

With growing concern over poor indoor air quality and air pollution, some homeowners are taking steps to monitor and control the air in their homes using apps and consumer air purifiers. This can lead to a false sense of security as the removal of gases and particulates from the air is a complex process. It requires mechanical ventilation and carbon filtration to treat the air throughout the home, and control the pollutants generated inside the home.

£20 billion is the estimated cost of air pollution in the UK. Reducing exposure to pollutants whilst at home can save lives and improve the quality of life. We spend an average of 16 hours a day at home, and often the most vulnerable members of our society, babies and young children and the elderly, spend substantially more time in the home.

With the right technology, the control of pollutants in existing homes is now achievable. While we wait for a long-term solution to air pollution, products like the Noxmaster should help reduce diseases like asthma, heart disease and cancer, and increase life expectancy for thousands of people.

Nuaire Marks Clean Air Day with School Events

Leading ventilation manufacturer Nuaire is highlighting national Clean Air Day today [21 June 2018] with an Air Quality Interactive Workshop with a local primary school, Cwrt Rawlin.  To highlight the dangers of air pollution, volunteers from Nuaire have also planted an Air Quality Garden at the school and are participating in a ‘green’ journey to work, leaving the car at home.

Air pollution harms the health of millions, leading to respiratory problems which are particularly detrimental to children and impact on their lung function growth.  According to a recent World Health Organisation (WHO) report, 44 UK cities have air too toxic to breathe safely.  Sadly, Caerphilly is home to Wales' most polluted road, the A472 at Hafodyrynys, where levels of nitrogen dioxide are higher than anywhere but central London. 

Clean Air Day is a chance to find out more about air pollution, share information with friends and colleagues, and help make the air cleaner and healthier for everyone.

Nuaire will host a class of 30 year 3 children from Cwrt Rawlin Primary School in Caerphilly. 

The Air Quality Interactive Workshop, which will run from 10am – 12pm, features engaging and fun presentations and scientific experiments looking at indoor air quality, how to reduce air pollutants in the home including positive input ventilation, and a Cyclone Ball game with teams challenged to remove the most ‘NOX particle’ balls.  Children will also be given a full factory tour, showing how ventilation products are made, from sheet metal being pressed to finished goods being loaded into delivery lorries. 

Yesterday [20 June 2018], as part of the event, a team of 11 Nuaire employees planted an Air Quality garden at Cwrt Rawlin School to encourage school children to think about ways to reduce air pollution. Silver Birch trees, Lavendar and Aster were just some of the pollution-trapping plants and trees included in the garden. 

Research by Citizen Sense into air pollution mitigation has shown that planting certain species of trees, low shrubs and plants can help reduce levels of Nitrogen Dioxide and Particulate Matter, whether through depositing particulates on leafy structures or taking up nitrogen dioxide. 

Children at the school will be able to learn about air pollution planting and the importance of green spaces in urban areas.

Nuaire Marks Clean Air Day with Launch of First Retrofit Carbon Filter PIV System

Leading ventilation manufacturer Nuaire, based in Caerphilly, Wales, hopes to prevent thousands of deaths caused by air pollution with what they believe is a revolutionary technology for existing homes.  To coincide with national Clean Air Day on 21st June, the company is launching the Noxmaster whole-house ventilation system for the retrofit market. 

The Noxmaster combines a powerful carbon filter with a strategy invented by Nuaire over 45 years ago, Positive Input Ventilation (PIV).  This combination removes up to 99.5% of nitrogen dioxide and other harmful pollutants generated by traffic emissions and industrial processes. The Noxmaster delivers clean, filtered air into urban homes, improving the indoor air quality to within safe levels, as recommended by the World Health Organisation (WHO). A recent WHO report cited 44 UK cities have air too toxic to breathe safely. 

The Royal College of Physicians estimates that up to 40,000 early deaths each year are the result of air pollution, with long-term exposure linked to lung and heart disease, asthma, stroke and cancer. Reducing exposure to air pollution is now a major government initiative, outlined most recently in the Environment Minister’s Clean Air Strategy.

Until now, using carbon filters to scrub airborne pollutants from indoor air has only been used with mechanical ventilation systems which are ducted from each room in a new build property. Retrofitting these systems into existing dwellings is both difficult and highly intrusive. However, Nuaire’s Noxmaster invention now means that any urban home with a loft can have a carbon filter ventilation system installed.

Nuaire Business Ops Director, Andy Mudie, explains the thinking behind this revolutionary product: “With rising air pollution levels, installing carbon filters in urban homes has become a planning condition in many parts of the country. But with an estimated 27 million existing homes in the UK, compared with 170,000 new homes built each year, the disparity is clear. The industry has been waiting for a solution for the millions of existing homes that are blighted by poor air quality, and this exciting new development addresses the issue for the wider population.

“Noxmaster is the first time a retrofitable whole-house ventilation system has addressed air quality with carbon filtration. It’s about giving homeowners and tenants living near busy roads the peace of mind that, by installing a system in their loftspace, their long-term health will be safeguarded.”

Noxmaster combines the PIV strategy with a powerful carbon filter that removes up to 99.5 of nitrogen dioxide and up to 75% of particulate matter (PM2.5). Exposure to NOX and PM2.5 reduces life expectancy through a range of diseases including lung cancer, dementia and diabetes.

Nuaire is currently running tests with Noxmaster at Hafodyrynys, Caerphilly - the most polluted street in Wales.  A controlled test house has been monitored for a number of months to show the difference between the pollution levels at the roadside, the pollution levels in a typical property, and the greatly reduced NOX levels with the Noxmaster installed. Test results are likely to be available in early August.

With growing concerns over air pollution levels, an increasing number of homeowners are taking steps to monitor and control the quality of their indoor air using consumer products such as air purifiers. Nuaire Product Development Manager, Richard Jenkins, believes this may lead to a false sense of security: “Removing gases and particulates from the indoor air is complex and requires a process that filters the air throughout the property.

Air purifiers can only treat the air in one room, and their effectiveness depends on the room’s exact size, its use and proximity to the roadside. In short, you would need a purifier in every room in the home and that would still be far less effective than providing a single source of filtered air through a mechanical system, as the Noxmaster does.”

Adding carbon filtration to PIV has another major benefit in that it keeps condensation levels low. Mr Jenkins explained: “The PIV process used by Noxmaster treats the whole property, ensuring the air is constantly diluted and replaced with fresh, filtered air. Humidity is a major indoor pollutant, which leads to condensation dampness and mould growth. It keeps moisture levels low, whilst also forcing out pollutants generated by household cleaning and beauty products, cooking with fuel and using wood-burning stoves.”

With over 400 staff based in Caerphilly, Nuaire is a large employer for South Wales and an integral part of the community.  To raise awareness of the importance of air quality, Nuaire is holding an Air Quality Interactive Workshop with a local primary school, Cwrt Rawlin, on national Clean Air Day. The Workshop, which runs from 10am – 12pm, features engaging and fun presentations and scientific experiments looking at indoor air quality, how to reduce air pollutants in the home including positive input ventilation, and a Cyclone Ball game with teams challenged to remove the most ‘NOX particle’ balls.  A factory tour will be included, showing Nuaire’s world class manufacturing facilities. 

As part of the event a team of eight Nuaire employees has also plant an Air Quality Garden at Cwrt Rawlin School to encourage school children to think about ways to reduce air pollution.

Have Faith with Nuaire

Ventilation manufacturer Nuaire has launched ‘Faith’, a new continuously-running extract fan designed specifically for Social Housing applications.

Small yet compact, the new FAITH fan has a facility to enable constant-flow operation via a sensor to guarantee installed performance. Unlike some other continuous extract fans on the market, Faith can automatically adjust its airflow to maintain the designed duty, enabling it to comply with ADF 2010 (system 3) once installed.

Sales Director, Andrew Sellman explained: “Within the repairs and maintenance sector, the testing and commissioning of continuous extract fans has been far less regulated than in the new build sector. Many continuous extract fans in the market are perceived to meet building regulations but upon inspection, they often don’t meet the required duty. As a result, the property is under-ventilated leading to problems with mould, condensation and poor indoor air quality.

“We have designed the new Faith fan to overcome this widespread issue of non-compliance, giving social housing providers the peace of mind that their extract fan will meet Part F and L of the Building Regulations and protect both the property and the tenant from damage caused by damp and poor air quality”, continued Mr Sellman.  

Even with its competitive price point, Faith extract fan comes with a number of sophisticated features.  An intelligent and energy-saving humidity tracker which continually measures the humidity levels in the home and adjusts the fan accordingly – ideal for addressing wet laundry, steamy bathrooms and cooking vapours.  An advanced run-on timer mode further supports this by automatically operating to tenants’ lifestyles. 

For tenants, the new Faith extract fan is small and sleek, and, just as importantly, is quiet in operation.  A night-time delay and intelligent run-on timer ensures a quiet operation when tenants are asleep, whilst also helping to save energy.

A cost-effective, low maintenance ventilation solution, Faith can be wall, ceiling and window mounted for maximum convenience and flexibility.  As a further benefit to social housing providers, the daily run monitor record tenants’ operation, providing potentially useful documentation.

Faith is available in 230V and SELV versions and is suitable for IPX4, for use in all zones within a domestic property.

The new Faith extract fan joins Nuaire’s full range of energy-efficient domestic, commercial and renewable ventilation solutions.  UK based with over 450 employees worldwide, Nuaire has been at the forefront of the ventilation industry since 1966.

IAQ-VALVE Twice Highly Commended in Industry Awards

IAQ-VALVE carbon filter supply valve removes harmful NOX from urban homes.

A unique carbon filtration air valve designed by Nuaire has earned two high commendations at the H&V News Awards 2018. 

IAQ-VALVE is a new and simplified method of preventing toxic fumes from vehicle emissions from entering urban homes. It combines a standard MVHR supply valve that is part of a ducted system with a powerful carbon filter, capable of removing up to 91% of NO2 and NOX.

Nuaire’s IAQ-VALVE carbon filter received the Highly Commended accolade in both the Air Movement Product of the Year, and Domestic Ventilation Product of the Year. Judges were impressed with the product’s ability to protect homeowners from harmful vehicle pollutants, and the unique combination of the supply valve with a carbon filtration – an industry first.

Illegal levels of nitrogen dioxide in many cities around the UK continue to make headline news, with the government in breach of safe levels set by the World Health Organisation. Increased road traffic now accounts for up to 65% of urban environmental pollution, which research suggests claims an estimated 40,000 lives each year in the UK. Annual mean levels of NO₂ near busy roads regularly breach legal levels, and as a result, people living in homes nearby are at risk of developing asthma, lung cancer, heart disease and dementia.

Carbon filters for new build homes and apartments have traditionally been designed in the form of in-line boxes. By combining a carbon filter cassette with a standard MVHR supply valve, Nuaire has simplified the installation and design process. With no requirement for an access hatch, specification and design are straightforward, and all the homeowner will see is a discrete, white ceiling valve.

Powerful filtration is combined – critically – with low resistance. The carbon media offers a low resistance to air volumes of up to 15l/s, so the optimum performance of the MVHR system is maintained.

Maintenance is straightforward. IAQ-VALVE has a simple ‘twist-and-clip’ bayonet fixture which enables quick release for easy maintenance that can be carried out by the homeowner without the need for tools. Nuaire recommends replacement of the cartridge every two years, offering a free-return recycling service to ensure the used media is disposed of correctly.

While the issue of air pollution is still far from being resolved in urban towns and cities, Nuaire remains confident that the IAQ-VALVE can protect homeowners from the life-threatening effects of dirty air.

'Game-Changing’ Carbon Filter Earns Double Award Nomination

HV news Award Nomination - Nuaire IAQ-VALVE

Nuaire’s passion for clean indoor air has been recognised by industry judges for the H&V News Awards 2018, with a double award nomination for the unique carbon filter supply valve, IAQ-VALVE.

New to the market this winter, IAQ-VALVE is the very first time a carbon filter has been added to a standard MVHR supply air valve, creating a solution to fighting incoming traffic pollution that is both easy to install and easy to maintain.

The new carbon filter technology has been shortlisted for Domestic Product of the Year and Air Movement Product of the Year, in the highly respected H&V News Awards. Residential Product Manager, Wendy Thomas said: “We are delighted to be nominated  in two categories. Indoor Air Quality is being taken more seriously with evidence from the World Health Organisation and leading health bodies like the Royal College of Physicians to show the loss of life and burden of disease linked to environmental air pollution.

IAQ-VALVE is a simple alternative to inline carbon filter systems that is easy to install and, crucially, easy for the facilities manager or occupant to change.  We are passionate about air filtration and it’s great to see that the heating and ventilation industry also see the benefit in developing this unique technology.”

Small but powerful, the carbon filter valve is capable of capturing up to 91% of NO₂ and other harmful pollutants, as verified by the BRE. The activated carbon media inside the cartridge is microporous so a spoonful equates to roughly the size of a football pitch.

IAQ-VALVE works as part of a complete system with Nuaire’s MVHR Eco range. The carbon pellets offer low resistance, up to 15l/sec, helping to maintain the correct system pressure.

With options to duct vertically and horizontally via a fixed plenum, installation is flexible and fast. Maintenance is simple with no access hatch required and tool-free replacement of the cartridge can be carried out by the homeowner.

The winners of the H&V News Awards will be revealed on 19th April 2018.

TWIST, CLIP AND BREATHE WITH NUAIRE’S IAQ-VALVE

Nuaire IAQ-VALVE carbon filtration technology

Ventilation manufacturer, Nuaire has developed a new carbon filtration technology to simplify the way designers keep air pollution out of the home. 

Increased road traffic now accounts for up to 65% of urban environmental pollution, which research suggests claims an estimated 40,000 lives each year in the UK. Annual mean levels of NO₂ near busy roads regularly breach legal levels, and as a result, people living in homes nearby are at risk of developing asthma, lung cancer, heart disease and dementia.

Today, Nuaire has unveiled IAQ-VALVE, a unique style of filtration that combines a standard supply air valve with a carbon filter. This combination is designed to simplify the control of air pollutants entering the home by utilising a standard MVHR supply valve that is part of a ducted ventilation system. With no requirement for an access hatch, specification and design are straightforward, and all the homeowner will see is a discrete, white ceiling valve.

Small but powerful, the carbon filter valve is capable of capturing up to 91% of NO₂ and other harmful pollutants. The carbon media held inside a cartridge is microporous and has a much larger surface area than its external dimensions suggest. A spoonful of activated carbon equates to the surface of a football field. Through a process known as ‘adsorption’, the pollutants are attracted and held on the surface of the carbon, trapping them before they enter the home.

Improving indoor air quality is a driving factor in the design of new products. Business Development Director, Andy Mudie explains: “IAQ-VALVE represents a new type of life-saving technology that simplifies the design and installation of carbon filters. The virgin activated-carbon pellets remove a reassuringly high level of pollutants produced from vehicle fuel combustion, including harmful NOX, sulphur dioxide, ammonia and VOCS, all of which are known to damage the body and reduce life expectancy.

“Removal of pollutants is the most important aim of any carbon filter product, but that must be followed by factors that make specification, installation and maintenance easier. We have considered the end user, designer and contractor in the unique design of IAQ-VALVE”, Mr Mudie said.

IAQ-VALVE works as part of a complete system with Nuaire’s low-energy MVHR Eco range. Polluted air is passed through the G3 filters inside the MVHR system, where particulates, pollen and dust are removed. This air is then passed through the carbon filter valve on the supply-leg of the ducting.

Powerful filtration is combined – critically – with low resistance. The carbon media offers a low resistance to air volumes of up to 15l/s, so the optimum performance of the MVHR system is maintained. The valve is fully adjustable for commissioning purposes and is lockable once commissioned, so even when the cartridge is replaced, the valve returns to the locked, commissioned position for guaranteed system performance.

The installation of IAQ-VALVE takes into account the varying availability of void space in new build homes and apartments. For deeper ceiling voids, the valve can be ducted vertically using rigid duct with the valve added after the ceilings are plastered around the duct opening. For lower ceiling voids down to 180mm, it can be installed using a first-fix plenum making connection simple.

Maintenance is equally straightforward. IAQ-VALVE has a simple ‘twist-and-clip’ bayonet fixture which enables quick release for easy maintenance that can be carried out by the homeowner without the need for tools. Nuaire recommends replacement of the cartridge every two years, offering a free-return recycling service to ensure the used media is disposed of correctly.

Nuaire will launch the new IAQ-VALVE at an event in London on 30th November, with members of the press and clients from the leading consultancies in London and the South East.

While the issue of air pollution is still far from being resolved in urban towns and cities, Mr Mudie expressed his confidence in the IAQ-VALVE and its effectiveness in protecting homeowners from the life-threatening effects of dirty air. “IAQ-VALVE is a unique, practical solution to the problem. All elements of the design have been considered in exacting details, from the simple method of replacement to the low-resistance. It is impressive how something so small and discrete can make such a positive difference to the air quality in new homes.”

FAN-tastic to Support Care Teens Through DIY SOS and Children in Need!

DIY SOS Big Build

Having been through the care system, Emma Lewis, chair of The Roots Foundation Wales, knows only too well the loneliness and difficulty that teenagers face when at 18 years of age they leave care to fend for themselves. Her desire to create a happy, safe space for children and teenagers in care led her to set up the Welsh charity, and with help from the DIY SOS team and Children in Need, Emma’s ambitious dream for a day centre with self-contained studio flats was realised.

Nuaire was privileged to support the epic Big Build project in Swansea with a donation of Cyfan extract fans, installed by Residential New Product Development Manager, Richard Jenkins. “We were delighted to step in and provide ventilation for the studio flats. The designs were really impressive and should provide a happy environment for teenagers leaving care. Our Cyfan extract fans will help keep moisture levels low, and even reduce strong cooking odours while they are improving their cooking skills!”, he said.

Our Cyfan centrifugal extract fans were installed in the apartment kitchens along with the communal kitchen. “Providing good indoor air quality will help protect the fabric of the new building, and keep condensation dampness at bay this winter”, explained Product Manager, Wendy Thomas. “We really are honoured to be involved in this special Children in Need and DIY SOS project. It was a very emotional story and we send out best wishes to Emma and her team for the fantastic work they carry out at Roots Foundation Wales.

Nuaire’s Solution for Cleaner Indoor Air Starts With Drimaster-Eco

The trend to insulate our homes to make them more energy-efficient is directly linked to poor indoor air quality, and the problem is growing. The fabric-first approach to building new properties means that homes are warmer and cost less to heat, but without adequate ventilation they simply cannot breath. The stale air laden with moisture and indoor pollutants remains trapped inside the property, causing real damage to the building fabric and, worse still, to our health.

Ventilation manufacturer, Nuaire has pioneered many products designed to improve indoor air quality. Residential Product Manager, Wendy Thomas believes that educating homeowners and housebuilders about the danger of poor indoor air quality is the best way raise awareness. She explained: “Poor ventilation is a wide-scale problem. It is estimated that one in five UK households are poorly ventilated, leading to problems with streaming windows, mould growth and poor indoor air quality.”

Everyday activities like cooking on a gas stove, burning fuel on stoves and fires, using household cleaning and beauty products, and creating too much moisture, all create pollutants that remain trapped inside the home.

Over time and without adequate ventilation, these pollutants which include carbon dioxide, nitrogen dioxide, Radon gas, Volatile Organic Compounds (VOCs) and formaldehyde, can contribute towards heart disease, asthma and even lung cancer. “Because we can’t see these pollutants, it’s easy to ignore the issue until health problems appear”, Mrs Thomas continued.

Countless studies have proven than whole-house ventilation is the best method of removing these pollutants and reducing moisture levels. Invented by Nuaire in 1972 and now installed in millions of UK homes, Positive Input Ventilation or PIV is trusted alternative to MVHR which meets building regulations and is the most cost-effective method of whole-house ventilation.

The PIV strategy works by providing a continuous supply of fresh, filtered air into the house through a fan mounted in the loft. The gently warmed input air enters the home through a ceiling diffuser, creating a positive pressure effect that reduces humidity levels and forces out air pollutants. The air is continually diluted, displaced and replaced to create a healthy indoor environment in which condensation cannot exist. PIV is also recommended as a measure to significantly reduce harmful Radon gas levels for homes in affected areas across the UK.

A New Direction for PIV

Nuaire has recently unveiled a new development in PIV technology. Drimaster-Eco offers increased energy and cost-savings to the homeowner whilst being quicker and easier to install.

Working closely with customers was crucial to development of the new range, explained Mrs Thomas. “Many developers still choose to use cheap extract fans which, when installed, may not extract the correct amount of air to prevent condensation and damp problems. Drimaster-Eco is the perfect solution. Not only does it meet the ventilation requirement within building regulations, but it is a whole-house ventilation system that saves energy whilst improving indoor air quality.”

The new Drimaster-Eco range offers increased energy-savings and user controllability through a host of clever features, but it is the ease and speed of installation that will most appeal to housebuilders, the manufacturer believes.

“Our Drimaster-Eco systems can be installed in under one hour by one tradesman, with no external core cutting, no duct runs and minimal disruption. Installing one of our low-energy systems negates the need for trickle vents and extract fans, saving time and money during the works programme. The new range is designed to simplify installation but at the same time to ensure that the most robust and effective ventilation system is in place”, said Mrs Thomas.

The new Drimaster-Eco range boasts four models which offer increasing degrees of performance and energy-efficiency to meet the exact needs of the homeowner.

A unique feature is the sleek, circular ceiling diffuser which houses the system controls. This allows complete control of the unit from the hallway without having to enter the loft.

Unlike other PIV systems on the market, the Drimaster-Eco range offers twice as much filter area so the filters are more effective for longer. Maintenance is minimal as the filters are changed every five years.

Both the Drimaser-Eco-Link and Heat models boast the new, enhanced hall-control with innovative remote control and sensor capabilities. A radio frequency receiver pairs the system with a range of optional remote and wired sensors and switches. The Relative Humidity and CO2 sensors enable the Drimaster-Eco to respond accordingly when moisture and CO2 levels reach a set level. The two and four-way switches allow the homeowner to turn the integral heater on and off as required, and to boost the system at times when added ventilation is needed. This simple functionality puts the homeowner in full control of their indoor environment. 

Mrs Thomas explained: “We are hugely excited to be the first PIV manufacturer to offer true demand-control through our sensors and controls. These unique features will allow the homeowner to tailor the operation of the Drimaster-Eco to suit their lifestyles and to save energy when the house is unoccupied.”

Another clever feature which sets the range apart from the competition is the unique location of the integral heater in the Drimaster-Eco-Heat model.  Sited between the flexible duct and the diffuser, this ‘pioneering design’ uses more of the heat created to temper the air rather than losing 3 to 4 degrees of heat through the duct as per standard PIV designs.

Nuaire anticipate that the Drimaster-Eco will surpass the huge popularity of is original and iconic Drimaster thanks to its use of new technology.  Mrs Thomas said: “Poor indoor air quality is never far from the headlines and improving it is the starting point in all of our new product developments. The Drimaster-Eco range solves the problems with minimal energy and cost, and we can foresee its new features, such as the wireless controls and sensors, marking an exciting change of direction for PIV.”

Drimaster-Eco Cuts Condensation for DIY-SOS Family in Bristol

A family fighting to bring their brain-damaged son home from hospital have had their dreams realised as their damp, cramped home is transformed by DIY-SOS, proudly supported by Nuaire.

Ryan Pollard, 24, has spent the last five years in a neurological centre, 50 miles away from his family in south Bristol, after a brain illness left him partially paralysed and in need of 24-hour specialist care.

Leading ventilation manufacturer, Nuaire donated its market-leading positive input ventilation system, Drimaster-Eco to the BBC TV series, DIY SOS – The Big Build, to help create a condensation-free, healthy indoor environment to support  Ryan’s on-going care and rehabilitation.

Unable to return home because his cramped, three bedroom house was not suitable for his wheelchair and too damp for his assisted breathing needs, Ryan had been forced to stay in hospital with daily visits from his mother.

The house needed a full ground-floor extension with a physio space, bedroom and wet room, with wheelchair access to the family kitchen and living areas. Without these facilities, a return home was not possible for Ryan, but with the generous support of local tradesmen and products from national suppliers, including Nuaire, the Pollard family have been reunited.

The Pollard family’s terraced property was described by DIY SOS presenter, Nick Knowles as ‘worryingly damp’ and ‘mouldy’. The wrong insulation, double glazing and leaky plumbing were cited as the cause of the black mould growing on walls and behind furniture.  Nuaire’s Drimaster-Eco PIV system was installed to prevent the build-up of condensation and improve the air quality in the home; vital to Ryan’s health and wellbeing.

Nuaire’s Residential Product Manager, Wendy Thomas explained: “Ryan and his family have been kept apart because their house was unfit for purpose. The work done by the DIY-SOS team was staggering and we are so pleased to have played a part in helping the Pollard family.

“The Drimaster-Eco system will allow them to breathe easily. It is designed as a fit-and-forget ventilation solution, only requiring a filter change every five years to maintain good indoor air quality. It’s the perfect solution for a family that have more important things to worry about, like helping Ryan to fulfil his goal of one-day walking again. It really is our absolute pleasure to contribute in a small way to such a life-changing scheme.”
