1. Chemical preparations
Represented by air fresheners, they are inexpensive, but they can only cover up some odors, and complex chemical reactions may occur under the influence of sunlight, which may become new air pollution. Therefore, it is impossible to purify the air to eliminate harmful gases.
2, chemical decomposition
The basic principle is the ionizer ozone generator, the price is relatively cheap, the function is more than the freshener, can increase the amount of negative ions in the air and reduce the solid dust in the air, has a bactericidal effect but has little effect on the decomposition of formaldehyde and other harmful gases. At the same time, the ozone generator generates a large amount of high-concentration ozone. While killing some virus bacteria, it may also kill human white blood cells, so it may cause cancer. Moreover, negative ions are easy to adsorb dust, and thus adhere to the indoor ceiling, which affects the appearance.
3, volatilization
It is a purifier with Chinese herbal medicine as the medium. It is cheap and has certain antibacterial effect. However, Chinese herbal medicine can not purify in the solid state, and the use of Chinese herbal medicine in purifier is only a trace amount. After saturation, it can not only be sterilized but also easy. Become a breeding body of bacteria. The replacement of the filter element at the same time involves difficulties in harmless handling.
4, adsorption
Mainly activated carbon filter, can absorb certain bacteria and dust and harmful gases in a short time, cheap, can filter certain bacteria and dust adsorption function, but no selective adsorption, the adsorption rate of water is 45%, generally It will be able to reach saturation after one month and needs to be replaced. Unable to recycle. After reaching saturation, it can not only be sterilized but also easily become a proliferation of bacteria. The replaced filter element also involves difficulties in harmless handling.
5, multi-layer filtration
Mainly for the composite purifier, the filtering effect is better, the solid dust in the air can be significantly reduced, but the price is high, and the filter device needs to be replaced after a period of use, and cannot be regenerated, and has no effect on harmful gases. More consumables and high cost of use. The replaced filter element involves difficulties in harmless handling.
6, catalysis, decomposition
It is mainly a photocatalyst purifier, which can decompose some harmful gases, and the price is relatively low. However, the photocatalyst is still in the experimental stage. The technology is not yet mature. The photocatalyst must rely on the ultraviolet light in the sunlight to produce the effect. The ultraviolet lamp is easy to be damaged and replaced frequently. At the same time, ultraviolet rays are harmful to the human body and plastics.
7, filter adsorption
The hydrophobic crystalline silica molecular sieve is mainly used as a filter medium. The effect is obvious. It can completely remove a variety of harmful gases such as benzene, xylene and chloroform. It does not adsorb water and air, and can effectively absorb a variety of harmful gases. The amount of adsorption is large, and it can be used for one and a half years. The filter material can be desorbed and regenerated using a simple method without creating a new source of contamination. The material has a life span of up to ten years and thus the maintenance cost is extremely low. It has little effect on reducing solid dust in the air, but it is also more expensive than other products.
