Air cleaning equipment

Principle of passive adsorption filter air cleaner

The passive air purifier mainly uses the fan to pump air into the machine, and then filters the air through the built-in filter screen. It can filter dust, smell, disinfect and so on. Filter screen air purifiers are mostly using HEPA filter + activated carbon filter + Photocatalyst (cold catalyst, far catalyst) + UV disinfection + electrostatic adsorption screen and other methods to deal with air. The HEPA filter has the function of filtering dust particles, activated carbon and other substances are mainly adsorption of toxic and harmful substances such as odor.

The principle of an active air cleaner

Active air purification principle is different from the passive air purification principle is that the air purifier active to get rid of the fan and filter limit, not to wait until the air is pumped in and then filtered through the fan after discharge, but effective and active release factor to air purification and sterilization, characterized by in the air, diffusion, arrive at each corner of the room the air purification effect of no dead.

Comparison of two cleaning principles

Compare the efficiency of air purification. Passive adsorption purifier using fan + filter model for air purification, one is to use the principle of air flow will inevitably exist dead, so most of the passive air purifier can only be placed a small space in the air purifier has certain purifying effect, only through a long time before the indoor air is filtered through all.

The active air purifier uses the characteristics of the diffuse nature of the air, so that the purification factor is diffused into each corner for air purification, so that the air can be diffused to the places where the purification effect can be obtained. Compared with negative ion air purifier, the negative ions can be actively attacked and found in the air to find the pollution particles in the air, and agglomerate with them to take the initiative to settle them. Only from this point of view, active air purification has obvious advantages.
