NOX50

The Brookvent NOX50 is a system which works hand in hand with mechanical extract ventilation (MEV) units, and has been designed specifically to remove outdoor pollutants from the air – most particularly particulate matter, and nitrogen dioxide, which can be drawn in from outdoor air by mechanical ventilation systems. The NOX50 is a nitrogen dioxide mitigation solution that is perfect used in conjunction with Mechanical Ventilation Heat Recovery (MVHR) in areas where the outdoor air goes beyond target concentrations of nitrogen dioxide, filtering these harmful gases and particulates out of the fresh air.

Product Brochure


  • Nitrogen Dioxide Mitigation Solution
    The NOX filter can be used in conjunction with MVHR (Mechanical Ventilation Heat Recovery) systems in buildings where outside air breaches target concentrations of Nitrogen Dioxide. By filtering air entering the building, residents and occupants are supplied with clean air in line with EU Directive Limits. The NOX Filter houses the tested Gas Filter Type 1 which can remove up to 90% of Nitrogen Dioxide, ensuring concentrations are brought below the Directive limits of 40 μg/m3 prior to entering the building.
  • Particulate Matter Filtration (PM10)
    The Gas Filter Type 1 is a uniquely designed combination air filter, fabricated to incorporate an internal PM10 Filtration Membrane filtering up to 90% of PM10 particulates that enter the NOX Filter.
