Understanding the Problem


Condensation dampness is more common than you may think, particularly in older homes and in new build properties that are poorly ventilated.  Excess moisture is produced by every day activities like bathing, cooking, washing and drying our clothes inside.  Condensed water provides the ideal conditions for mould spores already in the air to germinate and grow, damaging your walls, furniture and clothes, and contributing to health problems.  The humidity can also increase the number of dust mite allergens in the home, which aggravates the symptoms of asthma.  See our top tips on cutting condensation.


The importance of indoor air quality shouldn't be underestimated.  Pollutants are caused by cooking, washing and cleaning products, as well as the use of aerosols, decorating materials and smoking. Day to day activities can produce a range of chemicals and gases that enter the air and can damage your health long-term.  External pollutants, such as traffic fumes, pollens and naturally occurring Radon gas can enter the home through open doors and windows, trickle vents and airbricks, and the thousands of tiny gaps found in every home. 



Adequate ventilation will help cut condensation and rid your home of pollutants, creating a fresh and healthy indoor environment.  Nuaire offers a range of energy-efficient solutions to significantly improve your indoor air quality.

Positive Input Ventilation (PIV) is the UK's most popular method of low-energy, whole home ventilation and Nuaire is proud to have invented this technology in the 1970s. PIV brings a continuous supply of fresh, filtered air into the home through positive pressurisation, creating an environment in which condensation and mould can't exist and helping to reduce allergens and Radon gas levels.  Nuaire has low-energy PIV options for homes with or without lofts.

Extract Ventilation is designed to remove moisture from individual wet areas within the home. These individual fans are discrete and quick to install, and can also be used to enhance the performance of our PIV units. 



It's estimated that some 80% of asthmatics are allergic to dust mites. These tiny critters are too small to see by can be present in huge quantities in soft furnishings and, more worryingly, in our pillows and mattresses. Their faeces can also float in the air when you shake your bedding or walk over a carpet where they have settled. The inhalation of this allergen can trigger an asthma attack.

Dust mites thrive in humid conditions; just the sort of environment you will have if your home is poorly ventilated.  Using a Positive Input Ventilation system will ensure that allergens, pollutants and condensation are removed from the home, creating a hostile environment for dust mites.  Clinical research has proven that this type of whole home ventilation can play a significant part in controlling dust mite allergens, and Nuaire has hundreds of reports from satisfied customers who claim significant relief from their condition after installation of a Drimaster or Flatmaster PIV product.
