Can an air purifier remove formaldehyde? how to choose?mini air purifier

　　People in newly renovated homes and homes and offices buying new furniture are most concerned about how to purify formaldehyde pollution in the indoor environment through air purifiers. However, some consumers find that many air purifiers are no longer effective after being used for a period of time, and they mistakenly believe that air purifiers cannot remove formaldehyde.

　　According to the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center, some air purifiers currently on the market have the ability to remove formaldehyde. They generally use chemical technology to catalytically decompose formaldehyde in the air purifier. However, due to different design concepts and different product quality, there are certain differences in their purification capabilities.

　　Then, how can we choose an air purifier with better formaldehyde removal ability? We suggest that you can choose from the following eight aspects.

　　The first choice is a professional air purifier that removes formaldehyde. Most of the air purifiers on the market have the function of removing formaldehyde, but the products that professionally remove formaldehyde are more effective than general products after all. For example, Yaneng KJ-680H(W) is a comprehensive air purifier that has been upgraded 11 times over 4 years and is specially designed to deal with the pollution of newly decorated.

　　Second, look at the test report of the air purifier. If you do not simply want to remove formaldehyde, you must choose the one with higher formaldehyde removal ability among other types of air purifiers, and the method of choice is to look at the test report. You can see the evaluation data of the formaldehyde removal ability in the test report, and you can choose based on this. For example, the new national standard looks at CADR and CCM values, and must look at the data of formaldehyde instead of particulate matter. The CADR value of formaldehyde in the bedroom should be greater than 100, and the durability should not be lower than F3; the formaldehyde in the room of about 40 square meters such as the living room should be greater than 200, and the durability should not be lower than F4.

　　Third, pay attention to the purification efficiency of the air purifier (generally look at the experimental effect of 30 cubic meters an hour). If the purification efficiency is relatively small and the space to be purified is relatively large, it is difficult to ensure the purification effect of indoor formaldehyde. --- At present, for the old national standard or TVOC purification. Fine particulate matter PM2.5 is much easier to remove than formaldehyde!

　　Fourth, pay attention to the formaldehyde purification ability of the air purifier filter. The purification capacity of any filter is limited, it can only purify a certain amount of air pollutants, and formaldehyde pollution is no exception. If a sufficient amount of formaldehyde pollutants has been purified, the purification effect of the filter on the pollutants will be reduced. Choose products no less than F3.

　　Fifth, localized products are more reliable. Although formaldehyde pollution is not a “patent” in China, it is not as serious in other countries as in China. Therefore, whether it is a domestic brand or an international brand, the "localization" of products is particularly important, and export-oriented domestic brands or brands that directly import existing products into China will not deal with the problem of formaldehyde pollution. At the end of November 2017, Chongqing Yaneng KJ-680 series products competed with internationally renowned brands at the international online office, and the results showed that formaldehyde, TVOC, and smog PM2.5 all won to varying degrees (by Chongqing Municipal Environmental Protection Bureau senior engineers and more than 10 media Participate in the supervision and testing of the authoritative testing instruments of the Chongqing Academy of Environmental Sciences).

　　Sixth, credibility is very important. Therefore, when buying an air purifier product that removes formaldehyde, you must first check the brand's market reputation, so as not to be misled by publicity. At the same time, several products that are better for removing formaldehyde are relatively large.
