Why choose the Zehnder ComfoAir Pro 300 | G4/G4 Filter Set?

Indoor air quality plays a big role in your health and comfort. With this heat exchanger filter set for the Zehnder ComfoAir Pro, you ensure that your ventilation system continues to work optimally. The filters keep dust, dirt and insects out and ensure a clean air supply.

How does a heat exchanger filter work?

A WTW filter (Heat Recovery Unit filter) ensures that:

  • Polluted air is filtered out of the home.

  • Fresh outside air comes in purified.

  • The ventilation system lasts longer without blockages.

Advantages of this filter set

What filters are included in this set?

This set contains two G4 filters:

  • Outdoor air filter: prevents coarse particles and insects from entering the home.

  • Indoor air filter: protects the ventilation unit from dust and dirt from the extracted air.

How often should you change the filters?

It is recommended to change your WTW filters every 6 months. This prevents clogging and ensures optimal operation of your ventilation system.
