Filter class G3
Class G3 filters according to DIN EN 779 "Particulate air filters for general ventilation systems" are common coarse dust filters for ventilation systems. They clean the air of particles > 10 µm such as hair, (textile) fibres, spores and pollen, dust, fly ash, insects and sand.
G3 filters should be cleaned carefully!
Washing or cleaning with a hoover can damage the fine filter fabric to such an extent that the efficiency of the filter approaches zero. We recommend cleaning these filters very carefully or, ideally, using them only once and replacing them after 6 months at the latest. This way you will maintain a healthy indoor Climate.
