Xiaomi Mi Air Purifier HEPA Filter SCG4021GL for air purifier Review

Filter for Mi Air Purifier. Made in the form of a cylinder, in which HEPA has a class H13. This means neutralization of at least 99.97% of contaminants down to 0.3 microns. The filter traps viruses, bacteria, fungal spores, pollen and mechanical impurities, including PM2.5 and PM10 (the main components of smog). The pre-filter is a dense mesh that traps larger contaminants (crumbs, animal hair, wool, etc.). The carbon filter containing 330 g of activated carbon removes formaldehyde and other harmful substances, as well as unwanted and unpleasant odors. The efficiency of the replaceable cartridge is ensured by the circular design of the filter element using special materials and three stages of purification, which will make the air in the room perfectly clean. The use of a unique material using a special filter element manufacturing technology ensured reliable removal of heavy particles of small size. The material retains almost all microparticles flying in the air and practically does not slow down the air flow, providing an instant cleaning process.
