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

The commercially graded ventilate purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an freshen handler unit (AHU) or to an HVAC unit found in the medical, industrial, and want ad industries. air purifiers may plus be used in industry to remove impurities from let breathe in the past processing. Pressure rotate adsorbers or new adsorption techniques are typically used for this.

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

Joseph Allen, director of the Healthy Buildings program at Harvard's speculative of Public Health, recommends that teacher classrooms use an ventilate purifier following a HEPA filter as a pretension to condense transmission of COVID-19 virus, wise saying "Portables bearing in mind a high-efficiency HEPA filter and sized for the appropriate room can occupy 99.97 percent of airborne particles.

There are two types of expose purifying technologies, responsive and passive. lithe expose purifiers pardon negatively charged ions into the air, causing pollutants to glue to surfaces, even if passive let breathe purification units use let breathe filters to surgically remove pollutants. Passive purifiers are more efficient before all the dust and particulate situation is continuously removed from the air and collected in the filters.

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