With the rapid development of China's air purification equipment industry, the purification technology promoted by various businessmen is endless and dazzling. In fact, air purification equipment can be roughly divided into two categories: filtration and electrostatic dust collection. These two technologies have their own characteristics, but there are also corresponding deficiencies. Under the market condition of explosive growth, the technical development of air purification equipment needs to be breakthroughs.
HEPA filtration, negative ion, streamer energy, net ion group, photocatalyst, IFD, electrostatic dust collection... What is the difference between various technologies advertised in the market? How should ordinary consumers choose to buy?
It is understood that air purification technology can be divided into two main categories: filtration technology and electrostatic dust collection technology. Experts said that in the filtration technology, according to the different functions, it can be divided into dust collection filter, formaldehyde filter, activated carbon filter and HEPA filter, etc. Electrostatic dust collection technology uses the principle of high-voltage electrostatic adsorption to remove pollutants in the air.
Because the products using electrostatic precipitation technology are equipped with power electrodes and dust collecting network, the dust collecting network can be cleaned by washing, so the products using this technology are also called "consumables-free" products.
In filtration technology, according to the way of purification, it can be divided into physical and chemical forms. According to the material, it can be divided into glass fiber and P P polymer plastics. Electrostatic dust collection technology includes two ways: electric and motor drive. The traditional product of electrostatic dust collection technology is motor drive.
In fact, both negative ions, streamer energy and net ion groups are additional functions based on HEPA filter technology, which are used to capture bacteria and dust in the air and remove static electricity. Nowadays, all the air purification equipments equipped with HEPA filters in the market belong to the products using filtration technology.
Nowadays, electrostatic dust collecting technology is widely used in air purification equipment called "zero consumables" in the market. In addition, the IFD technology applied to air conditioning purification is actually one kind of electrostatic dust collection. According to experts, air conditioners with air purification function mostly use IFD technology, Qingdao Qingrun is the first manufacturer to apply this technology in air purification equipment.
Compared with the traditional electrostatic precipitator technology, the IFD technology is characterized by no ozone generation and sterilization.
The difference between filtration technology and electrostatic precipitation technology is that for all kinds of harmful substances in the air, filtration technology is "passive adsorption". Electrostatic precipitation technology is "active attack". Nowadays, the products using filtration technology account for 80% of the whole market.
Although the products using filtering technology now occupy the absolute mainstream, the shortcomings of HEPA filter which need to be maintained later are also very obvious. The electrostatic dust collecting technology is relatively low, which is closely related to its own technical defects.
