Filter mats

Filter mats are used in air purification to filter dust, pollen and larger particles from the air or as pre-separator to prevent the fine filters from clogging quickly. Thanks to their dense structure made of high-quality fleece or foam material, they efficiently capture dirt particles that would otherwise circulate in the air.

Our filter mats meet the filter efficiencies ISO Coarse 50-90% / G2-M5 and consist of pure materials such as silicone- and PVC-free polyester (PES discipline) or polyethylene terephthalate fiber fleece (PET).

Their progressive depth build-up traps coarse particles on the outside and finer particles in the middle of the filter, increasing air resistance more slowly and extending the life of the filter mat. In addition to their cost-effectiveness, these filter mats offer uncomplicated maintenance and can be easily adapted to individual needs.
