Passive adsorption and filtration purification principle:Passive air purification, is to use the fan to pump air into the machine, through the built-in filter filter air, mainly can play a role in filtering dust, odor, disinfection, etc.. This filter air purifier mostly uses HEPA filter + activated carbon filter + photocatalyst (cold catalyst, multi-catalyst) + ultraviolet sterilization + electrostatic adsorption filter to treat the air. Among them, HEPA filter has the role of filtering dust particles, other activated carbon, etc. is mainly the role of adsorption of odors, so it can be seen that the market with a fan filter, photocatalyst, ultraviolet, electrostatic and other different labels, seemingly very confusing air purifiers used in the work principle is basically the same, are passive adsorption and filtration air purification.
Active air purification principle: the active class of air purifiers and double purification class of air purifiers on the market generally choose only one active purification technology. There are mainly silver ion purification technology, negative ion technology, low-temperature plasma technology, photocatalyst technology and plasmacluster technology on the market. The fundamental difference between active air purification principle and passive air purification principle is that active air purifier gets rid of the limitation of fan and filter, not passively waiting for indoor air to be pumped into the purifier for filtration and purification, and then discharged through the fan, but effectively and actively releasing purification and sterilization factors into the air, through the air diffusion characteristics, to reach all corners of the indoor air The air is diffused to all corners of the room and purified without dead ends. Technically mature active purification technology is mainly using negative oxygen ions as a purification factor to treat air and ozone as a purification factor to treat air.
These two are typical air purifiers that work based on the active purification principle.
The above is a small introduction to some of these air purifiers, from these introductions can be seen, the air purifier is indeed the best air purification equipment, can effectively remove harmful substances in the air, to protect our health. In the future, if you want to buy an air purifier, you should still pick a good brand of products, and the purification effect of the product is also very important. I hope you can buy air purifier products suitable for your use in the future. I would like to recommend the air purifier of Olansi Healthcare Co., Ltd, which is not only of good quality, but most importantly, the company has foreign advanced production equipment and strict quality management system, and is an expert in OEM&ODM of health industry equipment.
