KASOgroup smoking cabins have the CE conformity marking
The principle of operation is based on a forced, controlled flow of impure air through a set of filters in order to rid it of odors and harmful substances. The filtration efficiency is no less than 99,99%.
The purified air is exhausted out of the cabin (but not back into it), so as not to interfere with its precise inner air circulation. This also prevents the unpleasant tobacco smoke smell from permeating the clothing of the people who are inside.
