Air purifier is one of the necessary cleaning equipment for our home and office. The core component is the air filter. Air filter is not only the important part of air purifier, but also the key device that determines the purification effect of the air purifier.

Air Filter

Air filter is a multi-layer composite material made of a variety of fiber materials, consisting of a pre-filter, medium filter, high efficiency filter and a post-filter. Pre-filter is used to filter large particles of dust, hair, dander and other substances, to protect the service life of the filter and extend the maintenance cycle of the filter. Medium filter and high efficiency filters are used for air purification, mainly to filter fine particles, viruses, bacteria, dust mites and other air pollutants, such as PM2.5, formaldehyde, TVOC, etc. The post filter is used to purify odors that remain after filtration, such as smoke and baking smoke odors.
