High-tech nonwoven fabrics
micronAir® office solutions against particulate matters, unwanted odours or harmful gases are based on environmentally neutral, fully recyclable nonwovens. They work via a three-layer structure and electrostatically charged microfibers to permanently remove even respirable ultra-fine particles from the air – regardless of the specific chemical composition of emitted particulate matter.
A multiple porgressive layer construction provides maximum protection against fine dust particles, odours and gases:
- pre-filter for larger particles
- middle layer of electrostatically charged microfibers
- additional high performing activated carbon layer for micronAir office combi filters
- extra-fine-pored layer for the very smallest particles
In all, micronAir® office filters effectively offer four filtration effects: gravitational, diffusion, electrostatic and sieve effect.
The properties of nonwovens
Freudenberg Filtration Technologies nonwovens possess excellent filtration characteristics. They form the basis of all micronAir® office particulate filters, giving them the following advantages:
 extremely high tear resistance
paper-free, so no risk of mold growth in damp conditions
freedom from bacterial and fungal growth in accordance with DIN EN ISO 846
environmentally friendly – halogen-free and fully incinerable
highly flame-retardant
