Clogged HRV Filter


Dirty or Clogged HRV Filter

Filters in your Heat Recovery Ventilation Unit need to be checked and cleaned regularly and replaced yearly.

Filters can get clogged very quickly and, where possible, should be cleaned with a vacuum cleaner every 3 – 4 months.

Reasons for filters getting clogged vary from area to area. Homes built in urban areas or along busy roads will get dirty more quickly. Homes with a larger number of people living in them will need to maintain their filters more frequently, as will homes with pets.

Most HRV Unit manufacturers recommend that filters are changed at least once per year. Changing the filters in most units is straightforward. Most units are designed so that the filters can be easily accessed.

By carrying out regular maintenance to your HRV unit, you will increase the life span of the unit and the heat exchanger.

Dirty or clogged filters can lower ventilation efficiency, damage motors and lead to poor air quality in your home.
