Zehnder ComfoAir E300/E400 FILTER SET (500X156X22)

Buy Zehnder ComfoAir E300/E400 filter set 500x156x22 online. This complete replacement filter kit ensures efficient air filtration for your Zehnder ComfoAir E300 and E400 HRV units with two filter options tailored to your indoor air quality needs.

What This Product Is

This filter set replaces both the supply and extract filters in Zehnder ComfoAir E300 and E400 heat recovery ventilation systems. Each set contains two filters sized 500x156x22 mm. Choose between the standard G4+G4 configuration for basic filtration or the efficient F7+G4 set for enhanced protection against fine particles. Both options maintain optimal airflow while protecting your ventilation system from dust accumulation.

Filter Class Comparison

Understanding which filter combination suits your needs:

• G4 filters capture medium-sized particles such as dust, textile fibers, and pollen. Suitable for both supply and extract air positions in environments with moderate air quality demands.
• F7 filters (ePM1 70%) trap ultra-fine particles down to 0.3 micrometers, including fine dust, bacteria, and combustion particles. Ideal for supply air filtration in urban areas, near traffic, or where higher air quality is required.
• G4+G4 set provides balanced basic filtration for both airstreams at a lower cost.
• F7+G4 set delivers superior incoming air quality with an F7 supply filter and G4 extract filter.

We recommend the F7+G4 configuration for homes in cities, near busy roads, or where occupants have respiratory sensitivities.
