Can an air purifier absorb dust? There is often a lot of dust in the indoor air. Because of the serious environmental pollution nowadays, there will be a lot of dust. Can an air purifier be used to clear the dust?
When the haze weather occurs, the air purifier becomes the new favorite of the family. Air purifiers can absorb, decompose or transform various air pollutants, including PM2.5, dust, pollen, etc.Because the characteristics of pollutants are different, dust and smoke are solid particles. The activated carbon filter currently on the market is already a mature technology. It can achieve a good purification effect for small solid pollutants like PM2.5. , Pollen and other large-particle solid pollutants are not to mention, you can rest assured to use household air purifiers.
The smart air purifier can suck dust. There are several layers of filters in the air purifier, which can filter out the dust and particles in the air, and only the air can be discharged from the air outlet. The dust can also be charged and adsorbed on the dust collecting plates on both sides by electrostatic dust collection. General air purifiers can remove dust in the air, but they cannot be removed when they are heavy and cannot float in the air.
The principle of air purifier adsorption of dust
1. HEPA filter
The HEPA standard filter can filter pollutants greater than or equal to 0.3 microns, with a filtration rate of 99.9%. The air in the HEPA filter can pass, but the fine particles cannot pass, so that the dust in the air can be filtered out.
2. Electrostatic dust removal
The tungsten wire of the electrostatic precipitator continuously releases high-voltage static electricity, so that the dust and bacteria that come in with the air are positively charged, and then adsorbed by the negative electrode plate. This can filter dust and smoke smaller than cells.
3. Negative ion technology
The main principle is to use static electricity to release negative ions. The negative ions combine with smoke and dust particles in the air to produce electrostatically charged smoke and dust particles. After being attracted by the ground, they will settle and play a role in purification.

What to do if the air purifier can't suck dust
1. Clean the dust collecting plate
If the wifi air purifier adopts electrostatic dust collection method, after a long time of use, the internal dust will deposit a lot, which will reduce the purification efficiency of the air purifier, and even cause secondary pollution, so look at the dust collector first. It is not already very dirty, just clean the dust collector and install it.
2. Replace the filter
If the HEPA standard filter is used, then you need to replace the filter. Generally, the HEPA filter cannot be washed with water. When the HEPA filter accumulates a lot of dust, you can only replace it with a new one.
