Air purifiers can effectively remove dust and particulate matter in the air, including PM2.5, PM10 and PM50. These particles refer to particles in the atmosphere with a diameter less than or equal to a specific number of microns. PM2.5 has a diameter less than or equal to 2.5 microns, PM10 has a diameter less than or equal to 10 microns, and PM50 refers to particles with a diameter less than or equal to 50 microns. .
Air purifiers use a variety of purification methods, such as filtration, adsorption, killing, sedimentation, decomposition and transformation, to isolate pollutants in the air inside the purifier, thereby improving air cleanliness. For the removal of particulate matter, air purifiers mainly rely on HEPA filters (High Efficiency Particulate Filters). HEPA filters are generally made of polypropylene (PP) or other composite materials and can filter out tiny particles such as pollen, dust mites, bacteria, and viruses in the air.
In air purifiers, there are also different types of filters such as primary filters (pre-filters) and activated carbon filters. They can work together to first filter out larger particles and then further filter them out through the HEPA filter. Smaller particles such as PM2.5, PM10 and PM50. In addition, some air purifiers are also equipped with functional equipment such as negative ions, which can also have a good effect on removing particulate matter.
In short, air purifiers can effectively remove dust and particulate matter in the air, including PM2.5, PM10 and PM50, thereby improving indoor air quality and having a positive effect on human health. However, it should be noted that different types of air purifiers may have different removal effects for different pollutants. Therefore, when purchasing, you should pay attention to its filter type, CADR value (clean air volume) and other performance indicators to ensure that you choose Buy an air purifier that suits your needs.
