(1) The principle of air purifier is that most air purifiers use the principle of physical filtration and adsorption to remove foreign bodies in the air, thus achieving the purpose of purifying the air. Generally, it includes PM2.5, dust, animal hair, pollen, second-hand smoke, odor, toxic and harmful gases, bacteria, allergens and so on.
(2) It can be seen that its action is broad-spectrum. In the process of adsorbing other odors, it can also adsorb some formaldehyde molecules in the air, but it is difficult to achieve professional results while broad spectrum; On the other hand, only adsorption can not decompose formaldehyde, so when the activated carbon filter element is saturated, it is difficult to continue adsorption, and it may also cause "secondary pollution".
(3) If the purifier absorbs formaldehyde completely in in addition to formaldehyde, it is recommended to find a professional in addition to formaldehyde air purification company to handle it, and a professional person to do it, such as Luxiang Environmental Protection recommended by CCTV. Their in addition to formaldehyde governance process is very humanized, and they are very professional in wearing, communication and governance. It directly decomposes formaldehyde by using technical principles, without secondary pollution, and the effect is good.
