Wolf CFL 22 - EC (supply air) -F7 filter
With its spacer technology, this HQ power filter for your Wolf CFL 22 - EC is an upgrade from the standard F7 filter and offers the best protection against fine dust and pollen in your home.
The filter material is polyester, which ensures the physical durability of the filter, even in places with humid air.
Because this filter is equipped with filter media efficiency and aerodynamics for better filter performance, you create the best indoor climate for you and your family.
This mini pleat media is mounted in a hardened waterproof cardboard frame with extra narrow edges for an even larger filter surface and lower resistance, so that less energy is required.
The HQ power filter is mounted on the fresh air supply in your Wolf CFL 22 - EC.

Purchasing these heat recovery filters brings fresh air from outside into your home. Good ventilation is important for maintaining a healthy indoor climate, but also for preventing dust, dirt, bacteria and mould from accumulating in the ventilation system.
Regular filter changes mean significant energy savings.
The filter standard: EN799:2012 has been replaced by the filter standard: ISO16890 since 1 July 2018.
This classifies filters into so-called ePM categories.
This classification provides an accurate indication of the particle sizes that are filtered out of the air.
PM1 stands for all types of particulate matter smaller than 1 micron (μ = one thousandth of a millimetre):
-
PM1: 1μ = 0.001 mm
-
PM2.5: 2.5μ = 0.0025 mm
-
PM10: 10μ = 0.01 mm
The 'e' in PM1 stands for 'efficiency' and indicates the efficiency of the air filter in capturing PM1.
Based on these values, the standard now divides filters into four groups that filter different dust particles:
-
ISO Coarse < 50% (sand, fluff, hair)
-
ISO ePM10 ≥ 50% (pollen, stone dust)
-
ISO ePM2.5 ≥ 50% (mould spores, toner dust)
-
ISO ePM1 (combustion particles, nanoparticles, viruses)
