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

The commercially graded freshen purifiers are manufactured as either little stand-alone units or larger units that can be affixed to an expose handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries. expose purifiers may along with be used in industry to surgically remove impurities from freshen back processing. Pressure stand-in adsorbers or extra adsorption techniques are typically used for this.

Dust, pollen, pet dander, mold spores, and dust mite feces can conflict as allergens, triggering allergies in pain people.

Joseph Allen, director of the Healthy Buildings program at Harvard's school of Public Health, recommends that college classrooms use an expose purifier later a HEPA filter as a exaggeration to shorten transmission of COVID-19 virus, wise saying "Portables taking into account a high-efficiency HEPA filter and sized for the take control of room can take control of 99.97 percent of airborne particles.

There are two types of expose purifying technologies, nimble and passive. nimble air purifiers forgiveness negatively charged ions into the air, causing pollutants to stick to surfaces, while passive freshen purification units use ventilate filters to sever pollutants. Passive purifiers are more efficient since all the dust and particulate business is every time removed from the air 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 expose (HEPA) filters and ultraviolet germicidal irradiation (UVGI).
