To coincide with national Clean Air Day on 21st June, Nuaire is launching the Noxmaster whole-house ventilation system for the retrofit market.
The Noxmaster combines a carbon filter with 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).
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 allows any urban home with a loft to have a carbon filter ventilation system installed.
Nuaire Business Ops Director, Andy Mudie, explained: “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 27m 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.”
The carbon filter also removes other harmful gases produced by traffic emissions, including sulphur dioxide, hydrocarbons and Volatile Organic Compounds (VOCs), helping to clean up the indoor air and protect the long-term health of the occupants.
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.
