High-efficiency M6 filter class hollow carbon filter for Siber EVO 1 and EVO 2 type ventilation devices with central heat recovery. The filters are easily accessible and replaceable without tools. The use of carbon filters should only be used during the period of the year when the quality of the air introduced from outside justifies this, i.e. unpleasant odors can be a problem for the user. The active carbon content of the filter binds and neutralizes a significant part of the odor molecules in the air passing through the filter. The replacement period of the filter is generally 2-3 months, but it largely depends on the air quality of the installation environment.
The efficient operation of the device and its expected lifetime are greatly influenced by the condition of the filter.

Features of the activated carbon filter:
Coarse particles: >99% (dust, pollens)
PM10 particles: >90% (mold spores, pet hair)
PM2.5 particles: >60% (particles of combustion products)
PM1 particles:
