There are many different technologies and media in the air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalytic technology, superstructure photomineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes: photocatalyst, activated carbon, Synthetic fiber, HEPA high-efficiency material, negative ion generator, etc. The existing air purifiers are mostly compounded, that is, a plurality of purification technologies and material media are simultaneously used. There are many kinds of indoor air pollution. The key targets are formaldehyde, benzene, pm2.5, inhalation allergens (dust mite, fungus, house dust, animal skin, pollen, etc.). Household users should use a composite ultrafiltration air purifier.

Applicable area of 鈥嬧媋ir purifier, applicable area = 0.07-0.12*cadr. For the air purifier in addition to formaldehyde, we have to look at the CAD value of formaldehyde removal. CADR Chinese name clean air output ratio, the higher the CADR value, the higher the purification efficiency of the purifier.


CCM. It is said that the soul of the air purifier is the product filter. In fact, there is nothing wrong with this statement. Only when the material and performance of the filter are up to standard, the product can achieve a good purification effect. Among the air purifier parameters, there is a strong correlation between CCM values. The CCM value represents the continuous purification ability of the product filter. The unit is milligram. Generally speaking, when the CADR value of the product is consumed to a certain extent, the weight of the pollutant accumulated on the product filter net, the greater the weight, the better the performance of the filter. The CCM values 鈥嬧媜f formaldehyde and particulate matter are different, which can be divided into F1-F4 grade and P1-P4 grade. The larger the CCM value, the longer the service life of the air purifier filter.

Fan. Efficient purification results from strong circulating air volumes, especially air purifiers with fans, which require good air circulation in the air purifier, which is the heart of the air circulation system. The standard requires that the air in the room should be filtered more than 5 times in the first hour, and the filter should be filtered every 12 minutes on average. The air volume is too small, and the harmful substances cannot be fully decomposed; the air volume is too large, which is obviously waste.
