Nuaire Unveils The Next Step In Carbon Filtration

As many as 40,000 deaths each year are being caused by exposure to air pollution, and rising Nitrogen Dioxide (NO2) and Particular Matter (PM10 and PM2.5) from traffic fumes are the major culprit.

Nuaire unveils a new range of carbon filters to help protect homeowners from rising air pollution levels in our traffic-congested towns and cities. The IAQBOX takes air purification to the next level, offering the highest levels of filtration and the lowest resistance of any system on the market. And while the range sets a new benchmark, it offers competitive pricing.

IAQBOX removes 99.5% of NO2 from the air, as verified by the BRE, making it the most effective system available. IAQBOX also removes chemicals produced through industrial processes and burning fossil fuels, as well as filtering out strong odours.

Nuaire’s carbon filter range has optional PM10 and PM2.5 pre-filters that ensure up to 95% of harmful particulate matter is removed from the intake air, with the G4 filters inside Nuaire’s MVHR system acting as a third barrier to airborne particles. This pre-filtering technology not only safeguards the health of the homeowner, but prevents build-up of harmful materials inside the MVHR system so it operates more effectively for longer.

Uniquely, the carbon ‘media’ is held in one block rather than a row of individual filters, which makes removal and replacement quicker and easier. Nuaire can guarantee a four-year lifespan for its filters, so maintenance is minimal.

With marked improvements in current levels of resistance and unique features, Nuaire aims to make this life-saving technology easier to specify. IAQBOX is available in two sizes for greater flexibility.

IAQBOX-D Double is an industry first. With a greater surface area to remove even more NO2, its double-width size reduces overall air resistance to the lowest levels of any carbon filter on the market. With resistance dramatically lowered, the fan can run at a lower speed which makes it quieter.

IAQBOX Double features a spigot configuration of ‘one-in, two-out’ that not only helps reduce pressure drop, but also acts as a plenum, cutting out an additional duct connection. In the same way, it acts as an attenuator, reducing in-duct noise.

The standard IAQBOX-S Single unit is both smaller and lighter for smaller homes. IAQBOX is mounted in the ceiling void. It measures just 170mm in depth, meaning a saving in valuable void space for apartments.

Importance of Indoor Air Quality in Energy-Efficient Homes

When it comes to evidence of how indoor air pollutants can affect our health, we’re certainly not short of compelling research. The report by the Royal College of Physicians, published in February 2016, highlighted to risks posed by poor indoor air quality, and put the NHS at the forefront of the debate on IAQ. This report, coupled with research from NICE and the World Health Organisation on the sources and effects of indoor air pollutants, gives weight to the arguments put forward by the ventilation industry that IAQ must become a greater focus by the government and within Building Regulations and for the Government.

A further report by Professor Awbi: ‘The Future of Indoor Air Quality in UK Homes and its Impact on Health’, argues that building regulations aren’t taking into account the impact of improved air-tightness and increased energy-efficiency on indoor air quality and people’s health.

Prof. Awbi recommends that there should be a legal requirement for new homes, and guidance for retrofitted homes, to have an air exchange rate of at least 0.5/hour to protect our health. Continuous mechanical ventilation is, he says, the most effective way of hitting these rates whilst saving energy. So for new build homes, MVHR is the key.

But what about the millions of existing homes across the UK, especially those in areas of high air pollution? What retrofit ventilation products will help? We see Positive Input Ventilation, a technology invented by Nuaire in the 1970s, as the more effective retrofit solution.

Nuaire’s Solutions For Improving IAQ

The ‘Fabric First’ approach to building new homes helps to achieve sustainability, high thermal performance and cost-efficiency without the need for solar technologies. These air-tight construction methods can result in poor indoor air quality as condensation and indoor pollutants remain trapped inside the home.

Adequate ventilation is key to the ‘fabric first’ approach. MVHR is still the most effective ventilation strategy for homes built with high thermal values and high air-tightness.  Our range of low-energy systems include models that are designed to fit around the size and use of the new build property. From low-profile systems designed to fit into apartments shallow ceiling voids, up to our largest units for properties with up to six wet rooms.

By running continuously, an MVHR system will extract stale air which has been contaminated by indoor pollutants whilst filtering out pollen, pollutants and dust particles from the incoming air, thus ensuring good indoor air quality.

Changes to Building Regulations Part L, which focus on conservation of fuel and power, have put an even greater focus on cutting carbon usage through improving the fabric energy-efficiency of new build homes. This is good news for the environment and for homeowners who will benefit from the 6% improvement on carbon reduction from the 2010 regulations; however, the regulatory changes don’t include advice on ensuring good indoor air quality. In an age where many homeowners filter their tap water through fear of drinking chemicals, many are unaware of the chemicals and pollutants they breathe in on a daily basis in stale air that is trapped inside the home.

At Nuaire, we are going a step further with the launch of our new Q-Aire Carbon Filter. It is specifically designed for homes in urban areas and it supports the MVHR system by ensuring the air is properly filtered before it enters the property. This measure protects the homeowner from damaging air pollutants such as carbon dioxide and nitrogen dioxide.

The Carbon Filter is suitable for specification and allows contractors to meet planning obligations when building homes and apartments in areas with high air pollution. We’ve designed it to be easy to install but also easy for the homeowner to maintain, because, as we know, effective maintenance is the only way to ensure the MVHR system does its job properly.  The filters are built with innovative Colourcell ™ technology, which provides a visual indicator of when the filters need to be changed: a simple change of colour. 

What Can Go Wrong If the Wrong System Is Specified?

Planning and installation are the key to an effectively operating MVHR system. Manufacturers like Nuaire offer a great deal of advice and support to consultants at the planning stage, to ensure that the right system is specified. However, a recent trend in apartment building is for MVHR systems to be selected based on the size of the cupboard or wall space, not on the requirements of the apartment. Added to this, the MVHR systems are then run at top speeds to tackle the common problem of over-heating, problematic in areas of high air or noise pollution where openable windows are ruled out by planning restrictions. A unit that is too small to ventilate the size of property, also run at maximum speeds to tackle over-heating, will no-doubt be noisy.

Nuaire has designed a solution to this problem with its Q-Aire 1Z, a unique all-in-one acoustic enclosure that removes breakout noise and vibration. This solution allows contractors to meet the strict noise requirements set out by CIBSE guidelines.

Positive Input Ventilation – Drimaster-Eco Range

As well as being able to provide more traditional mechanical ventilation solutions, Nuaire is able to offer an alternative and equally robust approach when heat recovery is not required. Our alternative approach is a strategy called is Positive Input Ventilation (PIV) which was invented by Nuaire back in the 1970s. It’s now installed in over 1 million UK homes as a low-energy, low cost solution to combat condensation and indoor pollutants, and it’s suitability to new build ventilation is now being recognised.

This 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, improving indoor air quality and helping to minimise the entry of harmful Radon gas.

PIV will work without the need for any trickle ventilators down to an air permeability of 3m3h/m2 ensuring an additional saving for the homeowner.

The Drimaster-Eco range includes three models. A unique feature is the sleek, circular ceiling diffuser which houses the system controls, allowing adjustments and commissioning to be carried out from the hallway without having to enter the loft.

Added controllability comes from the remote sensors and controls that instruct the PIV system to respond accordingly to changing humidity and CO2 levels. This controllability improves indoor air quality and helps save energy. Nuaire is excited to be the first manufacturer to full demand-control through these energy-saving controls and sensors. This development marks an exciting change of direction for PIV.

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. Small and light, the new unit offers an extended duct length to overcome installation restrictions, and can be hung at the right height to maximise heat gains within the loft space.

The Drimaster-Eco-Heat features an integral heater which is sited uniquely between the flexible duct and the diffuser. The unique heater position offers the same performance whilst using up to 20% less energy than the competition. This means lower running and life cycle costs.

Dynamic Insulation Spot On For Green Deal

Nuaire, the market leader in the design and manufacture of commercial and domestic energy efficient ventilation systems, and Energyflo, experts in dynamic insulation technology for both new build and retrofit projects, have teamed up to complete an innovative carbon reduction retrofit project for Willmott Dixon and South Cambridgeshire Council.

Rampton Drift is a development of properties in Longstanton, Cambridge. Willmott Dixon, main contractor for the project, was looking to explore different retrofit technologies in a bid to improve energy efficiency and reduce carbon emissions.

Alan Cochran, Technical Director for Wilmott Dixon, said: "Dynamic Insulation was selected because it is one simple solution that easily integrates the insulation and ventilation system to improve energy efficiency and indoor air quality."

Leading the design consultation process was PRP Architects, which specified Energyflo's dynamic insulation to be retrofitted to the properties' external walls. , Nuaire was appointed to provide the ventilation solution to meet the carbon reduction objectives of the project.

Andrew Peacock, Technical Director from Energyflo said: "One of the key aspects of our unique technology is that we can deliver the solid wall U-values in hard to treat buildings well beyond any other external wall insulation from a thinner and less intrusive build footprint.

"We chose to work with Nuaire because they are leaders in ventilation technology and could provide the technical support needed. Nuaire's Positive Input Ventilation (PIV) technology integrates easily with dynamic insulation to provide one simple solution, which is highly effective yet hidden in the home, reducing household bills for occupants".

The Minister for Energy and Climate Change, Greg Barker, recently visited Rampton Drift to witness the homes piloting the Government's new 'Green Deal' initiative.

Launching next year, Green Deal supports the implementation of energy efficiency measures to households and businesses to reduce energy usage and save fuel costs.

Andy Mudie, Marketing Manager from Nuaire, said: "we have been using Positive Input Ventilation for both existing and new properties for many years. PIV is an ideal retrofit solution as it is easy to install and unobtrusive. The Rampton Drift project has been an opportunity to link ventilation and dynamic insulation to create an exciting new low carbon solution ."

Following on from the success of Rampton Drift, similar projects are being undertaken elsewhere in a bid to lower fuel costs, reduce energy usage in existing housing stock and go some way to helping the country towards its carbon reduction commitment.

Nuaire Answers DIY SOS Call for Help!

When the DIY SOS team came to Monmouth to reunite a mother, devastated by a stroke, with her young family, Nuaire seized the chance to donate ventilation equipment.

The BBC DIY SOS programme filmed last April will air on TV tonight, telling the story of Charlotte Fairlie, her husband and her twin sons, whose lives were shattered when Charlotte suffered a major stroke just moments after giving birth.

Despite having just a one per-cent chance of survival, and suffering partial paralysis, brain damage and short-term memory loss, Charlotte has slowly taught herself to walk again and is making strides in her speech. 

However, the Fairlie family’s home was completely unsuited to the care and rehabilitation that Charlotte needed, and, with two babies to care for, the family were forced to spend much time apart.

Nominated for support from the prime-time BBC TV show, Charlotte’s home was transformed by a double-storey rear extension built to create a physio room and en-suite wet room, together with other adaptations to support the family.

Nuaire are proud to have supplied three Cyfan universal extract fans to ventilate the new parts of the Fairlie’s home, installed by Richard Petitt of RSP Plumbing and Heating.

The Cyfan extract fan is a powerful 60 litre extract fan that is quiet and very efficient. It will protect the fabric of the building and protect the home from excess moisture whilst improving the indoor air quality.

Residential Product Manager, Wendy Thomas, explained: “Our hearts went out to Charlotte and her family. We were delighted to play a small part in the transformation of their home which means that Charlotte can be with her husband and young sons whilst still receiving the care needed to get better.”

Nuaire learned of the Fairlie family’s plight through the brother of a Nuaire employee. Richard Petitt of RSP Plumbing and Heating played a key role in the installation of services to the new extension and was keen to involve Nuaire in the supply of ventilation equipment. 

Mrs Thomas continued: “Family is at the heart of Nuaire and the opportunity to help this family in need and support the brilliant work of the DIY SOS team has been truly rewarding.”

Watch this episode on BBC1 tonight, 9pm or on catch-up TV.

Nuaire advise on curing condensation – for good!

It’s at this time of year that poor ventilation is really obvious.  Streaming windows, lots of humidity and, for those that suffer the most, this could mean mould and dust mites in the home.

There are various ways to ventilate according to building regulations, from extract fans and passive stack to mechanical extract and MVHR (heat recovery). Yet, often overlooked is a ventilation strategy that sits under ‘alternative methods of ventilation’ - ‘PIV’ or Positive Input Ventilation.

PIV is the process in which fresh air is supplied by a fan located in the loft area into the upstairs landing area of a building, where air is tempered using the heat that naturally accumulates at the top of a house. It is then filtered and gently pushed into the home, causing positive pressurisation. By continuously supplying fresh, filtered and warm air this method displaces the damp, stale air that causes condensation, which escapes via natural leakage points. As a result, indoor air quality, and health, is improved.

The same PIV principle can also be applied in apartments and flats where a wall mounted unit delivers the air into a central corridor.

PIV was developed by Nuaire in the 1970s in conjunction with the North Eastern Gas Board, which was seeking a low cost solution to clear condensation and humidity caused by sealed up chimneys and modern central heating systems.

Wendy Thomas, Residential Product Manager at Nuaire, said: “People do not appreciate that bathing, cooking, washing and drying clothes creates up to four pints of moisture in the home per person per day. There’s no way to see this moisture until it clings and condenses on to colder surfaces – such as windows. This moisture can encourage mould and mites, which can trigger allergic conditions, such as eczema, conjunctivitis, rhinitis and even asthma.

“Positive Input Ventilation systems are proven to be quiet, energy efficient and shown to significantly improve indoor air quality with incoming air that is controlled and filtered.”

By filtering the air that enters the home, the process can reduce the overall maintenance costs of a property by protecting the fabrics and materials in a home. PIV is also a known method that can help reduce high levels of Radon gas within homes in affected areas.

Positive Input Ventilation is ideally suited to repairs and maintenance, yet is also gaining popularity in new build homes. So, if you are dealing with steaming windows, mould, radon gas or just considering all ventilation strategies, don’t forget about PIV.
