4 precautions for purchasing high-end formaldehyde-removing air purifiers?

　　1. Product "three high and one low" value

　　The three highs and one low of the new national standard are the criteria for judging the quality of a brand. The higher the CADR value, CCM value, and efficiency, the faster the air purifier purification speed, the better the effect, and the longer the filter life. The lower the noise, the better the experience and the more comfortable to use, so three highs and one low are a must-see when buying an air purifier.

　　2. Product inlet and outlet design

　　The air purifier has a variety of air inlet designs, such as single-sided air inlet, side air inlet, three-sided air inlet, and four-sided air inlet. Under the operation of the same power engine, the more air inlets, the greater the amount of air that can be entered, and the greater the air outlet. The bigger it is, the faster the purification rate of the product.

　　3. Motor and fan

　　The motor fan makes an air purifier operate as a basic device, and the power and quality of the motor and fan affect the purification effect, noise, performance, etc. of the product. The components of the motor fan are very important. The more precise the component, the smaller the friction. The lower the noise, the comfort is improved.

　　4. Filter device

　　The soul of the filter type air purifier, products without a filter have no purification effect, so filter technology affects the purification effect of the product. The stronger the technical strength of the filter device, the stronger the product performance.
