The smog filter is designed for effective filtration of the so-called particulate matter. The PM2.5 and PM10 particles are the main component of smog, which have an optical diameter of 2.5 and 10 μm(micrometres).
In the MOCarz-CA version prefilter I3 was replaced by an activated carbon prefilter (or activated charcoal).
The filtration efficiency (removal) of PM2.5 particles reaches up to 73%, and PM10 particles up to 81% (according to tests carried out with a dust particle measuring device). The smog duct filter consists of a sealed filter box and two filters: prefilter and smog filter.
It is recommended to install a smog filter on the supply ducts in domestic ventilation and heat recovery systems.
