If you notice carefully, you will see that the air vents in the purifier decrease in size as they get closer to the top. This pattern shows that as air is pulled in through the sides, it is cleaned and their movement is in the upward direction.

The purifier has a dual stage filtration mechanism. The air enters the purifier through the inlets on the sides. The unclean air first passes through the the pre-filter, it then removes large debris such as pet hair, dirt and dust. Secondly, it passes through the combination of True HEPA filter and activated carbon filter. The layers of fine fibrous materials of a true HEPA filter traps and removes 99.97% of air-borne particles of the size as small as 0.3 microns.
