Most air purifiers employ a combination of air filters to remove airborne particles from the air.

The pre-filter captures large particles such as insects, large dust particles, animal hair, and so on. After pre-filter, air goes through a carbon filter that removes bad smell to ensure that the air in your room is fresh.

From the activated carbon filter, the odor-free air goes through a HEPA filter. This highly effective filter is capable of removing minute particles that are as small as 0.3 microns. It is also capable of capturing up to 99.97% of airborne particles from the air. Fine dust particles are removed from the air by this filter.

In case you are looking for an air purifier that is capable of effectively capturing dust particles, regardless of their size, then you should go for an air purifier that utilizes the HEPA filtration technology.
