I believe that many households will use air purifiers. However, there are many brands of air purifiers on the market, so what do you know about air purifiers? Let me introduce you to the following!
      Which is the best way to choose an air purifier? In fact, the choice of a good air purifier needs to be considered in many aspects. The following are good air purifiers.
      (1) Purification technology. Purification technology is the primary factor that should be considered when purchasing an air purifier. It is represented by activated carbon and HEPA mesh filtration technology. It is the safest and most efficient filtration method at present; and chemical decomposition filtration is also better. Try to choose an air purifier with multiple purification technologies;
      (2) Filter grade. Different filter grades, the purification effect is very different. The higher the HEPA network grade, the smaller the diameter of the particles that can be filtered, and the better the filtration effect. At present, the common air purifiers on the market use H10H9 grade filters. The medium and high-end air purifiers generally use H12 grade filters, and very few high-end air purifiers use H13 grade filters. The H13 grade HEPA net is the top imported medical grade filter with the best filtration results.
( 3) The amount of air cleaned. The larger the amount of clean air, the larger the purification area of ​​the air purifier, and the more the number of purification cycles. The international standard is 5 times an hour. When purchasing, you should try to purchase an air purifier with a large amount of clean air.
With the above content, do you already know which air purifier is better? I hope everyone has to help!
