Systemair Save VTR 300 (PF) filtrikomplekt M5+F7 (originaal)

This filter kit includes two filters of different efficiency classes to protect against outdoor air and indoor pollution in ventilation systems.

• The description claims that the M5 filter aims to capture about 50% of particles 10 microns or larger, such as dust, pollen, and pet dander, to clean the outgoing air and reduce visible and general dust accumulation in the ventilation system.
• The description claims that the F7 filter aims to capture about 60% of very fine particles smaller than 1 micron, including bacteria, smoke, tobacco particles, mold, and forest fire smoke particles, to purify incoming outdoor air before it enters the room.
