Your HRV system is of course an important part of your home and must also be properly cared for, but how can you achieve this?

Changing the filter may be more frequently needed for some than for others. It is therefore important that you check the filters of your ComfoAir E 300 / 400 unit once every 1 to 2 months. This will prevent you from suddenly having unexpected problems. The colour of the filter often shows whether it needs to be replaced or not. Is your filter white or light gray? Then you can leave it in and check it again in 1 to 2 months. Is it dark grey or black? Then it is time to replace your ComfoAir E 300 / 400 filters.
