I want to buy an air purifier, it has a lot of hair loss nearby. What kind of one would be better to buy! A typical air purifier can do it~What if I want to remove secondhand smoke? Can it be done? Second hand smoke is also possible~But I've heard many people say that air purifiers are an IQ tax, right? Driving it every day is actually useless! Of course not! Nowadays, air purifiers are equipped with HEPA filters, which have excellent adsorption capacity!

I don't know if you also have an inexplicable sense of trust in plasma air purification devices (disinfectors) and air purifiers. If you really think so, then you need to take a good look at what I'm going to talk about today. The air purifier purifies the air through a filter screen. Although these bacteria are adsorbed by the filter screen, they still proliferate wildly in the purifier. As they accumulate more and more, there is a possibility of being blown out, which sounds very scary. So why does traditional purifiers have the problem of being unclean?

We need to start by understanding the working principle of traditional air purifiers. When polluted air enters the purifier, the characteristic of the HEPA filter is that air can pass through, but small particles cannot pass through, and bacteria will be captured by the HEPA filter. The filtration diameter of the HEPA filter can reach 1/600 of the hair, and even 100nm virus aerosols are not a problem. Moreover, since the HEPA filter is not the principle of screening, small particles are affected by diffusion effects and electrostatic forces, More easily captured. It is a more effective filtering medium for pollutants such as smoke, dust, and bacteria, but it is precisely because of this principle that bacteria and viruses can adhere to your HEPA filter for a long time. If they are not eliminated in a timely and appropriate manner, they will proliferate wildly on your filter.

What's even more alarming is that due to the limited scope of the air purifier, there are still countless bacteria and viruses hidden outside the purifier that cannot be sucked in. So how can we solve this problem? We should not only absorb viruses and bacteria, but also integrate "adsorption" and "disinfection and sterilization" into one, so that viruses and bacteria enter the countdown of their lives the moment they enter the purifier, and disinfection and sterilization is not that simple.
