Hello, now let me answer the above questions for you. The working principle and function of the air purifier, I believe many small partners still don't know the working principle of the air purifier. Now let's have a look!
1. Generally speaking, the purification principles of air purifiers can be divided into three categories: 1. The main principle of passive adsorption filtration passive air purifier is that air is pumped into the machine by a fan and filtered by a built-in filter screen, which can mainly filter dust, odor and toxic gases and kill some bacteria.
2. Filters are divided into dust filter, in addition to formaldehyde filter, deodorizing filter and HEPA filter.
3. Among them, HEPA filter with high cost has a very good filtering effect on particulate matter, and can decompose toxic gases and sterilize, and can inhibit secondary air pollution.
4. The quality of the fan and filter screen of this kind of product determines the air purification effect, and the position of the machine and the indoor layout will also affect the purification effect.
5.2. The fundamental difference between the principle of active release purification type active air purifier and the passive air purification principle is that the active air purifier gets rid of the restrictions of fans and filter screens, instead of passively waiting for indoor air to be pumped into the purifier for filtration and purification, it effectively and actively releases purification and sterilization factors into the air, and reaches every corner of the room through the characteristics of air diffusion to purify the air.
6. The technologies for purifying sterilization factors in the market mainly include silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and clean ion group ion technology.
7.3. Double purification (active purification+passive purification) combines passive purification technology with active purification technology. It has a filter screen, which can suck in air to adsorb harmful substances and actively release purification and sterilization factors.
