Air is forced through a filter and particles are physically captured by the filter. As of 2005, the most common methods were high-efficiency particulate air (HEPA) filters and ultraviolet germicidal irradiation (UVGI).FiltrationAir filter purification traps airborne particles by size exclusion. Passive purifiers are more efficient, since all the dust and particulate matter is permanently removed from the air and collected in the filters.Several different processes of varying effectiveness can be used to purify air. Active air purifiers release negatively charged ions into the air, causing pollutants to stick to surfaces, while passive air purification units use air filters to remove pollutants. Exposure to various components such as VOCs increases the likelihood of experiencing symptoms of sick building syndrome.Purifying techniques An air purifier placed under a tableThere are two types of air purifying technologies, active and passive. Smoke particles and volatile organic compounds (VOCs) can pose a risk to health. The garment was to be constructed from leather or airtight cloth, secured by straps.In the 1860s, John Stenhouse filed two patents applying the absorbent properties of wood charcoal to air purification (patents 19 July 1860 and ), thereby creating the first practical respirator.A few years later, John Tyndall invented an improvement to the fireman's respirator, a hood that filtered smoke and noxious gas from air (1871, 1874).In the 1950s, HEPA filters were commercialized as highly efficient air filters, after being put to use in the 1940s in the United States' Manhattan Project to control airborne radioactive contaminants.The first residential HEPA filter was reportedly sold in 1963 by brothers Manfred and Klaus Hammes in Germany, who created the Incen Air Corporation which was the precursor to the IQAir corporation.Use and benefits of purifiersDust, pollen, pet dander, mold spores, and dust mite feces can act as allergens, triggering allergies in sensitive people. A short pipe allowed breathed air to escape. A long leather hose attached to the rear of the helmet was to be used to supply air, the original concept being that it would be pumped using a double bellows. Pressure swing adsorbers or other adsorption techniques are typically used for this.Contents1 History2 Use and benefits of purifiers3 Purifying techniques3.1 Filtration3.2 Other methods4 Consumer concerns5 Potential ozone hazards6 Industry and markets7 See also8 References9 External linksHistoryIn 1830, a patent was awarded to Charles Anthony Deane for a device comprising a copper helmet with an attached flexible collar and garment. Air purifiers may also be used in industry to remove impurities such as CO2 from air before processing. The commercially graded air 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 commercial industries. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.
