Which strong domestic and foreign air purification

With around air pollution, haze intensifies, air purifiers become a hot spot, and space vehicles as daily contact with people, car air purification has become the focus of attention. In response to this consumer demand, many domestic auto companies are car air purification product as a prominent selling point.
Some experts said that the current domestic air purification products in the field of more than 95% of all activated carbon adsorption technology, and product quality varies greatly. “If strict accordance with the standards, many products are not sold in the market,” said one expert.
At the same time, for the current domestic consumers eager to buy foreign air purifier practice, some experts say these expensive products in the clean air, the effect is not necessarily good. “Foreign and domestic air situation is different, for example, domestic air, the biggest problem is particulate matter, PM2.5, etc. While these things less foreign air purifier more abroad to reduce pollen and some other substances. Therefore, foreign air purifier to get home to, may not be able to meet our requirements. ”
Experts said that currently used in several air purification, the use of high-voltage electrostatic dust collection technology scavenging effect of particulate matter is good, but the removal of formaldehyde, toluene and other harmful volatile organic compounds without much effect; negative oxygen ions and reactive oxygen technology for technology removal of formaldehyde, toluene and other harmful volatile organic compounds have a certain effect, but the effect is not good remove particulate matter, and will be accompanied by an ozone generator; activated carbon adsorption technology strong adsorption capacity, can effectively absorb harmful volatile indoor air formaldehyde, toluene, etc. gas, particulate matter is limited but clear effect itself will produce secondary pollution, the presence of absorption saturation; photocatalyst catalytic decomposition technology can effectively absorb indoor air formaldehyde, toluene and other harmful volatile gases, but in the clear particulate limited effect, low concentrations of formaldehyde, toluene scavenging effect is not good.
OLANS efficient air purifier can purify the air of formaldehyde, benzene, carbon monoxide, volatile chlorobenzene and other harmful substances and PM2.5, bacteria, viruses, pollen and other substances.
