The main principle is: the air is pumped into the machine by the fan, and the air is filtered through the built-in filter, which can mainly play the role of filtering dust, peculiar smell, toxic gas and killing some bacteria. Filter is divided into dust filter, formaldehyde filter, deodorant filter, HEPA filter, etc. The characteristics of this kind of product is that the quality of the fan function and the filter determines the purification effect, the placement of the machine and the indoor layout affect the purification is complete, and the indoor purification effect is not balanced. According to the active sterilization principle of these products can be divided into silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and net ion group ion technology.
