What are filters and why should I change them in my MVHR Heat Recovery System?

The filters in your MVHR Heat Recovery system are vital to your indoor air quality help protect the unit and prolong its life. There are two filters inside the unit - one for extract air and one for supply air. 

As air moves through the system, dust, debris, and grease starts to build up and the filters protect the motors and heat exchanger, whilst cleansing the air entering your home.
Filters for MVHR Heat Recovery System are recommended to be replaced every 6 months, but this is dependent on your outdoor and indoor air quality.  Units and filters in higher pollution areas may need replacing as little as every 3 months.
