This set consists of 2 filters with a bio plastic filter frame!
Plastics obtained from biomass give off only as much CO2 after use in conventional disposal as the plants absorbed from the atmosphere during their growth phase. Bio plastic is therefore climate-neutral and has only a minimal impact on the environment. Depending on the type of plastic, CO2 savings of 60% to 80% are achieved compared to conventional petroleum-based plastics.
Type: bio plastic filter frame
Dimensions: 500x197x17 mm.
Filter class: (G4) Iso coarse 60% - (F7) ePM1 70% ISO 16890

Zehnder no. JE StorkAir: 400100084
You can easily replace the WTW filters for the Zehnder Stork air WHR 930 | WHR 950 | WHR 960 yourself and install them in your WTW unit.
With the purchase of these wTW filters, you bring fresh air from outside into your home. Good ventilation is important to maintain the indoor climate of the home properly, but also to ensure that dust, dirt, bacteria and mould cannot accumulate in the ventilation system.
Regular filter changes mean significant energy savings.m
The filter standard : EN799:2012 has been replaced since 1 July 2018 by the filter standard : ISO16890
Here, filters are classified into so-called ePM categories.
This classification gives an accurate indication of which particle sizes 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' for PM1 stands for 'efficiency' and indicates the efficiency of the air filter in capturing PM1.
Using these values, the standard now splits filters into four groups that filter different dust particles:
-
ISO Coarse < 50% (sand, lint, hair)
-
ISO ePM10 ≥ 50% (pollen, stone dust)
-
ISO ePM2.5 ≥ 50% (mould spores, toner dust)
-
ISO ePM1 (combustion particles, nanoparticles, viruses)
