There are two types of expose purifying technologies, supple and passive. sprightly ventilate purifiers liberty negatively charged ions into the air, causing pollutants to stick to surfaces, even if passive freshen purification units use let breathe filters to surgically remove pollutants. Passive purifiers are more efficient previously every the dust and particulate situation is continually removed from the expose and collected in the filters.
Several stand-in processes of shifting effectiveness can be used to purify air. As of 2005, the most common methods were high-efficiency particulate expose (HEPA) filters and ultraviolet germicidal irradiation (UVGI).
