Whether you use a fresh air system or not, the air purifier is a must-have product, and the best combination is the best. In the face of the market's dazzling purifier products, friends who don't understand are sure to be forced and do not know how to choose. But as long as you follow the steps I have given you below, you can buy a purifier that meets your needs.
Air purifier chooses the first step: see the demandClearly what is the purpose of purchasing a purifier, filtering PM2.5 is of course one of its most important functions, but secondly, such as removing cigarettes and other odors, removing formaldehyde, removing allergens, etc., is also an air purifier can do. Another factor is the size of your use area, whether you need to move the purifier often, etc. Whether you need to put a purifier in each room, this will directly affect your budget.
Air purifier chooses the second step: see the purification methodGenerally speaking, the household air purifiers are divided into two types: electrostatic type and machine type. The principle is not described here, and it is simple to explain. The mechanical type means that the fan blows the dirty air to the filter screen, and the polluted particles are blocked by the filter screen, and the clean air is blown out from the other side of the filter screen to achieve the function of air circulation purification. The electrostatic purifier adds a strong electric field to the purifier space, and the contaminated particulate matter is charged by the electrostatic dust collecting member, thereby purifying the air.
However, the drawbacks of both are also present. Compared with the electrostatic type, the mechanical purifier has more noise and power, while the electrostatic type has a slightly lower purification efficiency and is prone to ozone. Ozone is also an air pollutant. Whether this secondary pollution is acceptable or not requires additional testing to determine that mechanical air purifiers do not have this concern.
In general, most of the domestic air purifier products are mechanical purification methods, which are absolutely mainstream, and there are few electrostatic products, plus ozone pollution. Therefore, it is not recommended to consider electrostatic air purification. Device.
Air purifier chooses the third step: see the priceThe price range of air purifiers is very large, ranging from a few hundred to more than 10,000. High-end purifiers may use higher-grade filters, quieter fans, higher purification efficiency, and smarter Operation method, etc. However, because the industry is still not very transparent, the pricing of manufacturers is not as close to the cost as mobile phones, so the water is still relatively deep. Although the expensive air purifier has its meaning, the advantage and the difference are not equal.
