The air purifier is suitable for a wide range of people, can effectively remove the dust in the air, eliminate odors, can be used to disinfect sterilization. If you have a pregnant woman or child at home, you need an air purifier.
Just after the renovation of the house or renovation, in addition to pay attention to open windows and ventilation, but also should be configured to the home of an air purifier, used to remove formaldehyde, because formaldehyde is always in the release, so the need for an air purifier. Air purifier is really very useful.
Air purifier through the fan speak air pumped into the machine, through the built-in filter, and there are activated carbon adsorption of formaldehyde and other pollutant gases, can play a role in filtering dust, eliminating odor, disinfection and so on. There are also some air purifiers that will actively release purification and sterilization factors into the air to achieve the effect of inhibiting impurities, antibacterial and bactericidal. Next, some of the air purifier parameters of the meaning of the simple popularization of it
Activated carbon: for gaseous pollutants, the use of activated carbon surface adsorption, used to adsorb formaldehyde effect is very good. >> HEPA mesh filtration technology: currently recognized as a safer and more efficient filtration method, but mainly to filter dust particles. >> photocatalyst, cold catalyst technology: decomposition of harmful gases, such as home furnishing chemical pollution aldehydes and benzenes >> anion, silver ion technology on behalf of the: can sterilize and disinfect, effectively purify the air; CCM value >> CCM is the cumulative amount of purification is the filter's entire lifecycle of pollutants that can be removed the total amount of the filter is simple to say that the filter is the durability of the degree of the new There are two sets of ratings for CCM in the national standard, for particulate matter and formaldehyde. Solid pollutants such as PM2.5 and other particulate matter, expressed in P, *** divided into 4 levels, from low to high is P1, P2, P3, P4, corresponding to the total weight of purified particulate matter. Gaseous pollutants such as formaldehyde and other harmful gases, expressed in F, *** divided into 4 levels, from low to high is F1, F2, F3, F4, corresponding to the total weight of formaldehyde purification.
The national standard stipulates that when the CADR value is reduced to half of the initial value, it is considered that the filter has failed and needs to be replaced. Therefore, it is usually considered that the higher the CCM value, the longer the filter life of the purifier, which can be maintained at a relatively high CADR value for a long time.CADR value>>What is the CADR value? We are in an environment where the air is moving, even if you close all the windows in your home, the air is still moving slowly, and at the same time the pollutants are constantly flowing in and out, so the concentration of particles in the indoor air is maintained in a dynamic balance.
Generally the higher the better, but there are some cases, that is, the CADR value source is not uniform, the new national standard clearly stipulates the air purifier CADR value, most of the brands are based on this to show the test report, but the new standard is only a reference and not mandatory, there are still a lot of brands will be looking for a third-party testing organization to do the test report.
