Replace filters? When?

Replacing your Stork filter is important to keep your unit running in top condition. This should be done when the filter starts to turn dark gray or black. Then the air pressure becomes too high for your HRV unit and it will no longer work properly. If your Stork filter is light gray or even just white, you don't have to do anything. It is recommended to check the filters once every 2 months and to replace them at least every six months.
