The full name is Clean Air Delivery Rate, which means the clean air output rate. The higher the CADR value, the faster the purification speed. The CADR value is divided into two, one is "particle CADR" and one is "formaldehyde CADR". Depending on whether the main function of each air purifier is to remove particulate matter or formaldehyde, the corresponding CADR value is higher. The particulate matter includes PM2.5, dust, and the like.
The full name is Cumulate Clean Mass, which means the cumulative purification amount. The larger the CCM value, the longer the life of the filter. CCM is also divided into "particulate matter CCM" and "formaldehyde CCM". Particulate matter CCM value greater than 12000mg is P4 grade (highest grade), and formaldehyde CCM value greater than 1500mg is F4 grade (highest grade).
Air purifiers on the market usually contain 3-5 layers of filters. Common types of filters are pre-filters, activated carbon filters and HEPA filters. The front filter mainly absorbs small dust particles; the activated carbon filter can adsorb harmful gases such as benzene and toluene; the HEPA filter is the abbreviation of high-efficiency air particle filter element, which is currently the most recognized internationally most efficient filter material for capturing particles Strong capacity, large adsorption capacity and high purification efficiency.
