Most units have a warning on the control panel that indicates when it is time to change the filter. We recommend changing the filter twice a year , in spring and autumn.

Filters should be replaced because: Get clean and sufficient air into the house. To prevent condensation in the unit in winter or too hot in the unit in summer. It also helps maintain effective heat recovery, and gives the unit a longer life, which in turn leads to less need for service and cleaning of ducts.
