Air purifier opens the era of ultra-micro purification.mini air purifier wholesale

　　With the popularity of smog and the improvement of people's environmental awareness, air purifiers have become a very familiar class of electrical products. Filter purifiers, negative ion purifiers, the endless stream of purification equipment is dazzling. But in fact, different air purifiers represent different eras of purification technology.

　　Go up! The evolutionary theory of the development of negative ion air purifiers

　　First used for fire fighting purposes

　　In 1823, two people named John and Charles Dean invented a new type of smoke protection device in order to prevent firefighters from the attack of smoke when they extinguished fires, which greatly protected the personal safety of firefighters.

　　In 1854, Johns Tenhouse showed the world a foreign version of "The Yangtze River Back Waves Pushes Forward Waves"-an improvement on the invention of his predecessors. Through experiments, he learned that adding charcoal to the air filter can filter out harmful and toxic gases from the air, which also adds new functions to the air purifier.

　　Slowly, the air purifier has gradually matured, and it can be said that it has experienced three generations of purification technology.

　　1.0 Purification technology-fiber filter type

　　Filtration technology is the earliest generation of air purification technology, generally suitable for simple foreign air. But at present in China, this kind of purification technology is still the most common in the family.

　　The principle of filter technology is to use a fan to draw air into the machine, and filter pollutants in the air through the built-in filter. The advantage is that the price is cheap, and in terms of installation, it can be bought and used. With its solid market foundation, the filter air purifier quickly became popular under the impetus of the smog, and the limelight was no different for a while.

　　It is undeniable that the filter air purifier does play a certain role in purifying the air, especially for large-particle pollutants. But at the same time, due to the size of the filter pore size, although it can effectively filter large particles such as PM10, it is difficult to filter the particles below 2.5 microns that can enter the lungs. Therefore, even the most advanced HEPA filter manufacturers have publicly claimed. And when the filter is easily saturated, if it is not replaced in time, it is easy to cause secondary pollution of indoor air. Moreover, the later maintenance costs are relatively large, causing more troubles.

　　According to the big data on air purifiers released by Aowei.com, the current sales of filter air purifier products have shown a downward trend, and mainstream products use household-grade filters of grade 11-H13, and use medical health-grade filters above H14. The products are rare.
