Step 2: the air is filtered
Dust, pollen, animal hair and VOCs are kept in the EPA11 filter which is an air filter, acronym for Efficiency Particles Arresting filter. EPA11 is a standard that applies to any device capable of filtering, in one pass, at least 95% of particles with diameters greater than or equal to 0.3 µm. This filter will allow a maximum of 5% particles of 0.1 µm per liter of air to pass.
Activated charcoal, on the other hand, will mainly destroy odors, as in kitchen hoods. Activated carbon is in the form of a light, black powder, consisting essentially of carbonaceous material with a porous structure.
