A purification door is a device that can purify the air and remove pollutants. Its working principle mainly includes three aspects: filtration, sterilization, and circulation. Firstly, the purification door removes particulate matter from the air through filtration. Purification doors are usually equipped with multiple layers of filters inside, including primary filters, medium filters, and high-efficiency filters. Primary filters are mainly used to remove large particles such as dust, pollen, etc; Medium efficiency filters are used to remove smaller particles such as bacteria, viruses, etc; Efficient filters can remove smaller particles such as PM2.5.
