There are two types of freshen purifying technologies, alert and passive. responsive expose purifiers pardon negatively charged ions into the air, causing pollutants to pin to surfaces, while passive ventilate purification units use freshen filters to cut off pollutants. Passive purifiers are more efficient back all the dust and particulate event is for eternity removed from the air and collected in the filters.
