Running an air purifier is the best way to improve the quality of indoor air. These devices use internal fans to suck the air and send through several filters before circulating back to the living area.

Theoretically, the air-filtering process removes unwanted particles from the air which we can’t breathe. But how do air purifiers work? Read the content of this blog and check the best air purifier consumer reports.

Fans pull air in

Fans are installed in the air purifier that pulls air from the surrounding and pushes it back to the room. In the meantime, the air flows through filters that absorb pollutants like dust, pollen, and pet dander. In most of the purifiers, you will find different fan speed options available with the help of which you can easily change the speed of filtering the air.

Filters take particle out

In most of the air purifiers, the particles are trapped in the filter through the mechanical process. The fan pulls air in and cleans it out. Two types of mechanical filters are Pre-filter and true HEPA filter.

Pre-filter

Pre-filter traps pet fur, hair, and other large particles before it puts into the main filter. Some prefilters can be washed and are disposable. When you purchase an air purifier, you will find the guidelines written in the guided manual related to the age and after how many months you need to replace the filter.
