Internationally accepted methods of purchasing air purifiers, refer to the following:
One, whether or not it has a scientific purification principle, to achieve efficient air purification effect
1, the internationally accepted principle of air purification there are five, physical, electrostatic, chemical, anionic and composite. Generally speaking, air purifiers that use a variety of purification methods at the same time will have a better purification effect. For example, dust, odor, pollen and other large particles can be filtered by physical purification methods; while allergic substances, viruses, formaldehyde and other harmful substances require chemical purification methods.
2, according to the purification method from the direction of can move to points, and active purification (air purification) and passive purification (fixed-point purification) and the main passive composite purification of three. Passive purification mode only on the inhalation of air purification effect; active purification mode of the entire space will have a purification effect. Active-passive composite purification is a combination of the two, the effect is also better.
Two, whether to meet the specific purification needs
1, as far as the air purifier is concerned, the purification function is the most concerned function. If the requirements for indoor air purifiers are only based on improving indoor air quality, you can choose the type that simply purifies the air and is cost-effective.
2, such as working in a closed air-conditioned room, because the dehumidification effect of the air conditioner makes the air in the room become very dry, and the skin becomes dry, so when choosing an air purifier, buy a humidified air purifier with a beautiful skin function.
2, such as is and long-term in a crowded, indoor pollution environment, the need to breathe close to the fresh and bacteria-free air, in the purchase of air purifiers, will favor a small suitable for the desktop k air purifier.
3, the car car air purifier is suitable for some of the vehicle driving process cabin air environment requirements of the high crowd.
Three, combined with market sales and third-party authoritative certification to buy
1, a high-quality home air purifier, must have the ability to remove bacteria, odor purification. When choosing an air purifier, pay particular attention to its ability to remove bacteria and odor whether it is not a good name. Generally speaking, sales volume is a key market test index. If the product is good, the natural sales go up, the product is not good reputation poor buyers will be correspondingly much less.
2, in addition, like furniture under the table, sofa mattresses and other dirty air concentrated places breeding white staphylococcus, Escherichia coli, influenza virus and other common bacterial plankton; the newly renovated house is full of formaldehyde, benzene and TVOC and other harmful gases. The purifying effect of air purifiers on these harmful substances will be more convincing if verified by a third-party authority.
Personally, I think the above method of buying an air purifier is more objective and practical.
