Domus Ventilation launches in-line filter for improved air quality

Sustainability Fri, Oct 25, 2019 8:45 AM

Domus Ventilation, part of the Polypipe group, has launched its first ever in-line carbon filter range – NOX-FILT – designed to improve indoor air quality by preventing harmful airborne contaminants, including up to 99.5% of nitrogen dioxide (NO²) pollution, from entering a home.

Designed to work on the supply leg of the ducting system of a mechanical ventilation system, NOX-FILT works seamlessly with the system to deliver fresh, filtered air into the main living areas of homes. A low profile means it readily fits into restricted spaces.

There are two units in the range; the first being the NOX-FILT which houses a carbon filter cell only and the second, the NOX-FILT2.5, having the added benefit of a PM2.5 pre-filter to maximise the filtration of particulate matter equal or larger in size to 2.5 microns. Carbon filtration is a proven technology, with wide ranging pollutants attracted to the surface of the carbon and absorbed. With safe levels of NO² and PM2.5 regularly breached in the UK, these pollutants are a major cause for concern to public health having known links to allergies, asthma, lung cancer, chronic obstructive pulmonary disease, cardiovascular disease and even dementia.

With new homes in the UK designed with energy efficiency in mind, minimising air leakage has been a key priority. This has subsequently led to the increasing popularity of mechanical ventilation systems to bring in air from outside to replace stale indoor air that can be hot, stuffy and even damp. However, in areas where the external air is heavily polluted - often from transport but also from energy generation and domestic and industrial combustion - that air needs to be filtered as otherwise the air quality remains poor indoors, if less stale and humid.

The NOX-FILT from Domus ventilation is a cost-effective means of achieving this in new build properties and has been designed to work with the company’s range of high-performance mechanical ventilation systems, including the HRXE, HRX2D and HRX-aQ MVHR ranges, as well as with other manufacturers’ systems.

Exceptionally easy to use, the NOX-FILT has no adjustable running functions and the only maintenance required is filter replacement, which is quick and simple. The life expectancy of the main carbon filter is two years and the PM2.5 filter one year, depending on the installation environment.

Domus Ventilation has a well-deserved reputation for quality, supported by excellent technical support, from a market leading manufacturer and designer. It is well placed to offer immediate, practical solutions to Building Regulations Parts F & L.
