Portable air purifiers are generally also called mini air purifiers, air fresheners, and air cleaners. So how does portable air purifier work？They are capable of adsorbing, decomposing or transforming various air pollutants such as PM2.5, dust, odor, formaldehyde and other decoration pollution, bacteria, etc. , Products that effectively improve air quality are mainly divided into home, vehicle, commercial, and office. At present, the general air purifiers on the market can only remove dust, oily smoke and peculiar smell; slightly better ones can kill bacteria and viruses; high-level purifiers can eliminate chemical pollution such as formaldehyde and TVOC caused by decoration.
The biggest highlight of the portable air purifier is its small size, which can be carried around and can bring fresh air to users all the time. The purification outlet of the portable air purifier is facing the breath of the mouth and nose, and provides a steady stream of purified fresh air one-to-one. The design feature is based on humanized breathing indicators, usually ensuring that every mouthful is fresh. pure. In addition, there are many types of portable air purifiers, some can be worn directly on the neck, some can be placed in the car or on the bedside table, and some are a small mask; then the corresponding price and brand are all Is different. Moreover, different portable air purifiers are made of different materials, and their prices and specific functions are also different.
how portable air purifier works-the working principle of portable air purifier
The principle of passive adsorption and filtration air purification: Passive air purification uses a fan to draw air into the machine, and filter the air through a built-in filter, which can filter dust, odors, and disinfect. This kind of filter type air purifier mostly uses HEPA filter + activated carbon filter + photocatalyst (cold catalyst, how far catalyst) + ultraviolet disinfection + electrostatic adsorption filter and other methods to process the air. Among them, the HEPA filter has the function of filtering dust particles, and other activated carbons are mainly used to absorb odors. Therefore, it can be seen that there are various labels on the market such as fan filters, photocatalysts, ultraviolet rays, static electricity, etc., which seem to be very chaotic. The working principles of the air purifiers are basically the same, and they are all passive adsorption filter air purification.
Principle of active air purification: The fundamental difference between the principle of active air purification and the principle of passive air purification is that active air purifiers are free from the restrictions of fans and filters mesh, instead of passively waiting for indoor air to be drawn into the purifier. The interior is filtered and purified, and then discharged through a fan, but effectively and actively releases the purification and sterilization factor into the air. Through the characteristics of air diffusion, the air in all corners of the room can be purified without dead corners. At present, the more mature active purification technology in technology mainly uses negative oxygen ions as a purification factor to process air and ozone as a purification factor to process air. These two types are typical air purifiers that work based on the principle of active purification. Actively emit negative ions and other substances to actively kill the surrounding bacteria or pollutants, but this method is okay in a closed environment, and there is almost no in an open environment, and like the first type, it takes a certain time to function. Too late to purify. In addition to purifying the air, the negative ions released by the purifier can enhance human immunity, improve myocardial function, lower blood pressure, enhance myocardial function, improve sleep, and promote human metabolism.
The working principle of the portable desktop air purifier is actually quite simple. It is the same as the air purifiers you usually use at home, except that this product is a reduced version. When we need to buy and use an air purifier in the future, we can see that the portable air purifier is a very good choice. It can let everyone breathe fresh air all the time. I believe it can definitely bring us a lot of Good use effect.
In addition, the capacity of the filter screen of an air purifier is limited. In the case of severe air pollution, the filter screen will become saturated after a few months of use, and it needs to be cleaned or replaced regularly. If it is cleaned irregularly and when the humidity is right, bacteria will multiply on the accumulated dust. At this time, the air purifier will not only not be effective, but will become another source of pollution.
