Purchasing these wtw filters will bring fresh air from outside into your home. Good ventilation is important to maintain a home's indoor climate, but also to ensure that dust, dirt, bacteria and mould cannot accumulate in the ventilation system.
Regular filter changes mean significant energy savings.
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)
