Indoor Air Pollution NO2 Mitigation – The Legislation

The EU Directive 2008/50/EC (the CAFE Directive) European Union Air Quality and Clean Air for Europe 2008.


Indoor Air Carbon Filter Systems for NO2 Removal in Air Quality Management Areas (AQMAs)

indoor air pollution residential

AAC NITROSORB Carbon Filters are widely recommended by Air Quality Consultants and specified by Mechanical Consultants involved in Residential, Commercial and Educational Indoor Air Filtration and Ventilation projects in Air Quality Management Areas (AQMAs) where there is a specific need to mitigate NO2 pollution levels of indoor air in line with current legislation.

NOx Filters for Mechanical Ventilation Heat Recovery Systems (MVHR)

The AAC Swiftpack® NITROSORB® Carbon Filter System incorporates AAC NITROSORB® media into the AAC PR filter cells to deliver a high-performance NOx (NO and NO2) reduction solution that is compatible with Mechanical Ventilation Heat Recovery Systems (MVHRs). This competitively priced solution offers the benefit of longevity, alongside low pressure drops, with no increased energy consumption from the indoor ventilation system.

A custom/bespoke design and manufacture service is available to suit projects with multiple flow rates and where Site restrictions apply. This Service is offered at no additional costs.

NOx Filters for Horizontal and Vertical Air Flows

The AAC Swiftpack® NITROSORB® Filter System is compatible with horizontal and vertical airflow designs. These compact NOx filter units are suitable for a wide range of volume flow rates and can be made to present a low profile suitable for installation into a false ceiling void as low as 100mm. They also meet the low pressure drop requirements of Mechanical Ventilation Heat Recovery units (MVHRs) installed under part F of the Building Regulations.

PM10 or PM2.5 can easily be removed by the installation of a suitably rated particulate pre-filter, thus enabling them to comply with the particulate aspect of the legislation.

NOx Carbon Filtration Systems for Centralised Air Handling Plant

For projects with Centralised Air Handling plant the AAC NITROSORB® filter cells can easily be installed by means of the AAC Swiftkit® or the AAC Skeleton-Frame.

AAC Swiftpack® NITROSORB® Filter System with Colourcell®

The unique AAC Colourcell® Media Filter System is a patented transparent filter cell which contains a specially formulated media designed to change colour from white (New Media) to pink when the AAC NITROSORB media is spent.

This provides end users and maintenance technicians with a clear indication of the status of the NITROSORB® media and to when a media replacement project should be carried out. The results can of course be further verified by analysis of a media sample in the laboratory.
