What is the Zehnder ComfoAir E pollen filter?
The Zehnder ComfoAir E G4/F7 pollen filter is specially designed for heat recovery (HR) units. This filter improves indoor air quality by filtering coarse particles and fine dust from the air.
Why is filtration important in your CHW system?
A properly functioning WTW system needs clean filters. Contaminated filters reduce air quality and can cause health problems. This particular filter captures more than 60% of particles >10 microns and 60% of particles between 0.3 and 1 micron, ensuring cleaner indoor air.
What do G4 and F7 mean in air filters?
-
G4 filter (Coarse 60%): removes coarse particles such as dust, hair and sand from the air.
-
F7 filter (ePM1 60%): Filters fine dust and pollen, ideal for people with allergies.
