An ventilate purifier or ventilate cleaner is a device which removes contaminants from the freshen in a room to enlarge indoor ventilate quality. These devices are commonly marketed as inborn beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.

The commercially graded expose purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and flyer industries. air purifiers may afterward be used in industry to sever impurities from expose in the past processing. Pressure interchange adsorbers or further adsorption techniques are typically used for this.

Dust, pollen, pet dander, mold spores, and dust mite feces can prosecution as allergens, triggering allergies in pain people. Smoke particles and volatile organic compounds (VOCs) can pose a risk to health. exposure to air to various components such as VOCs increases the likelihood of experiencing symptoms of ill building syndrome.

Joseph Allen, director of the Healthy Buildings program at Harvard's speculative of Public Health, recommends that college classrooms use an expose purifier gone a HEPA filter as a mannerism to edit transmission of COVID-19 virus, saying "Portables when a high-efficiency HEPA filter and sized for the appropriate room can seize 99.97 percent of airborne particles.

There are two types of freshen purifying technologies, responsive and passive. lively air purifiers release negatively charged ions into the air, causing pollutants to pin to surfaces, though passive air purification units use air filters to separate pollutants. Passive purifiers are more efficient before every the dust and particulate event is continuously removed from the air and collected in the filters.

Several alternative 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).
