An air purifier or expose cleaner is a device which removes contaminants from the expose in a room to count indoor let breathe quality. These devices are commonly marketed as innate beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.

The commercially graded freshen 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 announcement industries. let breathe purifiers may afterward be used in industry to sever impurities from freshen back processing. Pressure swing adsorbers or additional adsorption techniques are typically used for this.

Dust, pollen, pet dander, mold spores, and dust mite feces can clash as allergens, triggering allergies in sore people. Smoke particles and volatile organic compounds (VOCs) can pose a risk to health. exposure 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 studious of Public Health, recommends that bookish classrooms use an freshen purifier like a HEPA filter as a way to edit transmission of COVID-19 virus, motto "Portables in imitation of a high-efficiency HEPA filter and sized for the take possession of room can take control of 99.97 percent of airborne particles.

There are two types of air purifying technologies, swift and passive. sprightly air purifiers release negatively charged ions into the air, causing pollutants to stick to surfaces, even though passive air purification units use air filters to surgically remove pollutants. Passive purifiers are more efficient before every the dust and particulate business is forever removed from the let breathe and collected in the filters.

Several vary 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).
