Does the air purifier have radiation?Air purifier price

　　The radiation of the air purifier can be said to be minimal, and when the air purifier is used, it is generally used in the corner of the room, so the radiation is negligible for pregnant women or children.

　　From the principle of air purifier technology to see if there is radiation:

　　HEPA filter

　　High efficiency particulate air filter (HEPA) is one of the most popular technologies used in air purification. The standard HEPA filter can absorb 99.7% of suspended particles of 0.3 microns in size (0.3 microns is the most difficult to filter size), but its wind resistance is relatively large, and it is rarely used in air purifiers. Actual air purifiers Is the HEPA declared by the manufacturer actually HEPA? Its filtration efficiency is slightly lower than HEPA, and the wind resistance is relatively low. Whether it is the real HEPA or the publicized HEPA, it makes the inhaled air fresher and cleaner. The advantage of HEPA filter is that it is effective and safe, and it is the most important technology for removing particulate pollutants in the air.

　　Electrostatic electret filter technology

　　The use of non-woven fabrics loaded with electrostatic electrets to collect dust is an upgraded version of HEPA technology. The advantages are low wind resistance, high efficiency, high dust holding capacity, and the most important thing is safety, while ultra-low impedance ensures energy saving. This technology is widely used in well-known construction fields such as the Bird's Nest and the Capital Airport.

　　Activated carbon filter

　　Activated carbon for air purification is an internationally recognized high-efficiency adsorption material. As early as the "World War I", it was used in gas masks. Activated carbon is widely used for air purification in cars or indoors. Activated carbon is a porous carbonaceous material. Its developed void structure makes it have a large surface area, so it is easy to fully contact with the poisonous and harmful gases in the air. The strong adsorption force field around the activated carbon pores will immediately become poisonous. Gas molecules are sucked into the holes.

　　Dust collection technology

　　The principle of high-voltage electrostatic adsorption is used to remove particulate pollutants in the air, such as dust, soot, pollen, cigarette smell and kitchen oil fume. The disadvantage of this technology is that it is easy to produce ozone, and only has an effect on large particles such as particles. The disadvantage is that it is necessary to pay attention to the safety of electrical appliances, it is difficult to clean, and it is easy to produce ozone. It must be properly designed to reduce the ozone emission to below a safe concentration. Ozone can kill bacteria. It may kill human white blood cells while killing some viruses and bacteria. Therefore, it is generally not used in household air purification products.
