MCERTS Tested NOx Filters & Verified Up To 92% Efficiency

We provide market-leading NOx filter solutions designed to combat indoor air pollution arising from Nitric Oxides (NO) and Nitrogen Dioxide (NO2).

Our NOx filters are MCERTS tested and verified up to 92% efficiency and have been deployed in Residential, Commercial and Educational buildings across many UK Air Quality Management Areas (AQMAs).

Air Pollution and The Legislation

The EU Directive 2008/50/EC (the CAFE Directive) European Union Air Quality and
Clean Air for Europe 2008 set stringent levels for Nitric Oxides (NO) and Nitrogen Dioxide (NO2)
in designated Air Quality Management Areas (AQMAs).


The Impact of this Legislation on the UK Construction Industry

This legislation has significant implications for Planners, Developers and Mechanical Consultants who are involved in new build projects in the residential, educational and commercial sectors. To comply with this legislation, developers must implement acceptable mitigation measures where the external air quality (NO2) being entrained into the building exceeds an annual mean of 40ug/m³.
