In order for your heat recovery ventilation system to work correctly and effectively, maintaining good indoor air quality and energy efficiency,  it is important that the filters are changed at least every 12 months and we recommend that they are checked more frequently. If your house is located near a busy road or other source of pollution it may be necessary to change the filters more often.  Your filters keep your heat exchanger and supply air ducting clean and operating well by collecting household and external pollutants.

Changing the filters is straightforward and does not require any tools, our system design allows you to easily access them. Full instructions are available in your user manual or please see our demonstration video.

If you, or someone living in the household, have asthma or other respiratory issues and you would like to discuss the best filter options for your system please contact us.
