Description

Zehnder ComfoAir 70 filters are original, high-quality recuperator filters designed for efficient filtration of supply and exhaust air. These filters help ensure clean indoor air and protect the ventilation unit from contamination.

Filter set options

Zehnder offers two original filter sets for this device:

Standard set – G4 + G4 (#527005180)

Zehnder calls it the "System Protection Filter Set". It consists of two G4 class filters for device protection and basic comfort.

• 2 × G4 (Coarse 60%) filters
• Traps large particles, sand and insects before they enter the premises
• Protects the heat exchanger from dust from the exhaust air
• A practical choice for everyday use

Efficient set – F7 + G4 (#527005190)

Zehnder calls it the "Hygiene Filter Set". It consists of an F7 filter for supply air and a G4 filter for exhaust air.

• 1 × F7 (ePM1 50%) filter for supply air
• 1 × G4 (Coarse 60%) filter for exhaust air
• Captures pollen, fine dust, mold and bacteria
• Recommended for people with allergies or sensitive respiratory tracts

Differences between G4 and F7 filters

G4 filter

The G4 filter retains at least 60% of large particles larger than 10 microns - soil particles, large pollen, plant debris, insect wings, sawdust, sand and textile fibers. It protects the recuperator from dust accumulation, thus maintaining quiet operation, lower energy consumption and a longer system life.

F7 filter

The F7 filter captures at least 50% of fine particles, 0.3-1.0 microns in size – bacteria, smog, tobacco smoke, combustion dust, spores and pollen. It purifies the outdoor air entering the premises, making it especially useful for allergy sufferers or those living in areas with heavy traffic or urban pollution.

• Larger filtration surface area
• Better particle collection
• Longer service life

When to change filters?

Zehnder recommends changing the heat exchanger filters every 3-6 months. The frequency of replacement depends on the level of air pollution, allergies, pets or smoking in the room, and dust from nearby construction sites. If the unit has a filter replacement indicator, follow its warnings - otherwise, visually inspect the filters.
