PM2.5, PM10 and PM50 refer to particulate matter in the atmosphere with a diameter less than or equal to a specific number of microns. Among them, the diameter of PM2.5 is less than or equal to 2.5 microns, the diameter of PM10 is less than or equal to 10 microns, and PM50 refers to particulate matter with a diameter less than or equal to 50 microns. The higher the concentration of these particles in the air, the more serious the air pollution becomes.

When people breathe the air, these particles can enter the human respiratory tract. PM2.5 particles are small and can enter the bronchi and alveoli of the human body, causing a great impact on human health, such as causing coughs, asthma, cardiovascular diseases, etc. PM10 and PM50 particles are larger and generally do not enter the alveoli, but they may still cause respiratory symptoms such as throat discomfort and coughing.

Air purifiers can effectively remove dust and particulate matter in the air, including PM2.5, PM10 and PM50, thereby improving indoor air quality and reducing the impact of these particulate matter on human health. When choosing an air purifier, you should pay attention to its filter type, CADR value (clean air volume) and other performance indicators to ensure that you choose an air purifier that suits your needs.
