Nuaire launches IAQ-VALVE indoor air filter

Caerphilly-based ventilation manufacturer Nuaire has launched a new carbon filtration technology, which it claims will ‘simplify’ the removal of air pollution from new-build properties.

Launched to the market this week, IAQ-VALVE incorporates a standard supply air valve with a carbon filter, which the company claims is capable of capturing up to 91% of NOâ‚‚ and other pollutants.

Nuaire says that 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.

The company adds that installation of the system is simple as it requires no access hatch in a property.

For deeper ceiling voids, the valve can be ducted vertically using rigid duct with the valve added after the ceilings are plastered around the opening. For lower ceiling voids down to 180mm, it can be installed using a first-fix plenum.

IAQ-VALVE has a ‘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.


The company’s business development director, Andy Mudie, said: “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.”

He added: “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.”

The system is designed to work alongside Nuaire’s Mechanical Ventilation and Heat Recovery (MVHR) Eco range. This works by passing polluted air through G3 filters, where particulates, pollen and dust are removed. This air is then passed through the carbon filter valve on the supply-leg of the ducting.
