As the public's understanding of air quality deepens and the pursuit of quality of life and health increases, air purifiers have become increasingly popular in urban families. The air purifier market has gained significant development opportunities, and at the same time, an overwhelming variety of air purifier brands and products have emerged.

Can air purifiers really purify the air?

Whether air purifiers can really purify the air is a doubt many people share—wanting to buy one but worrying if it will truly solve the problem. Air purifiers can indeed achieve air purification. The principle of an air purifier is to detect the PM2.5 concentration in the air. When the concentration reaches a certain threshold, the air purifier starts the air exchange and purification functions, inhaling and using filters to trap particulate matter, thereby achieving the effect of purifying the air.

What is the difference between dust sensors in air purifiers at different price points?

In addition to different purification effects, a fundamental difference between air purifiers at different price points is the dust sensor used. The sensor in a purifier is equivalent to human senses like ears, nose, and eyes—a way to obtain external information. Only after the PM2.5 sensor detects the concentration of air particles can the purification response be made. Lower-priced air purifiers are equipped with infrared dust sensors, while higher-priced air purifiers use laser dust sensors. There is a significant difference in accuracy, and consequently, the operational performance is also different.
