Indoor Air Pollution NO2 Filter Systems

indoor air pollution

AAC Eurovent offer a range of standard and bespoke NO2 Filters systems designed to combat Indoor Air Pollution in Residential, Commercial and Educational Buildings.

Our high-performance systems are widely recommended by Air Quality Consultants and are regularly specified by Mechanical Consultants involved in Residential, Commercial and Educational Indoor Air Filtration and Ventilation projects in Air Quality Management Areas (AQMAs) in London and major cities across the UK.

Built for economy and performance, our NO2 Filters are based on the independently tested AAC NITROSORB® and are designed to deliver an effective and long-term mitigation solution for NOx -Nitric Oxide (NO) – Nitrogen Dioxide (NO2).

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.


Mechanical Ventilation Heat Recovery Systems (MVHR)

The AAC Swiftpack® NITROSORB® Filter System incorporates AAC NITROSORB® media into the AAC PR range of media filter cells to deliver a high-performance 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 design and manufacture service  is available to provide different sized units to suit multiple flow rates.

Horizontal and Vertical Air Flows

The AAC Swiftpack® NITROSORB® Filter System is compatible with horizontal and vertical airflow designs. These compact 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 (NO & NO2) Filters for Centralised Air Handling Plant

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.
