Indoor Air NOx (NO and NO2) Mitigation for Mechanical Ventilation Heat Recovery Systems (MVHRs)

The AAC Swiftpack NITROSORB® Filter System is designed for ventilation systems that are connected to an MVHR unit.

This high-performance NOx filter solution incorporates AAC NITROSORB® media into the AAC PR filter cells and 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.



 Typical Applications:

  • Residential Apartments
  • Hotels
  • Student Accommodation
  • Universities / Schools / Colleges

Key Benefits:

  • Can be accommodated in a false ceiling void as low as 100mm.
  • Units meet the low pressure drop requirements of MVHR units installed under part F of the Building Regulations.
  • The NITROSORB® units can be positioned either downstream (preferred) or upstream from the MVHR unit.
  • When situated upstream of the MVHR unit, the NOx filter needs to be fully insulated to mitigate against the effects of condensation.
  • Suitable for use in a wide range of volume flow rates.

  • G3 after-filter / pre-fitted as standard.
  • Optional PM10/PM2.5 filter can be installed into the unit.
  • Smart remote system monitoring available.
  • Bespoke design service available.
  • PM10 or PM2.5 particulate pre-filter can be fitted to comply with the particulate aspect of the legislation.
