There are two types of freshen purifying technologies, alert and passive. sprightly expose purifiers release negatively charged ions into the air, causing pollutants to fasten to surfaces, while passive ventilate purification units use let breathe filters to separate pollutants. Passive purifiers are more efficient since all the dust and particulate issue is all the time removed from the ventilate and collected in the filters.

Several swap processes of varying effectiveness can be used to purify air. As of 2005, the most common methods were high-efficiency particulate air (HEPA) filters and ultraviolet germicidal irradiation (UVGI).
