A:Answer We would like to let you know that the Shark® Air Purifier is equipped with a 3-stage HEPA filter that is designed to capture 99.98% of particles down to the 0.1–0.2 micron range, plus odors and VOCs. The cylindrical structure pulls air through the back and sides of the unit and passes it through the HEPA filter. Particles such as smoke, mold, and allergens are then trapped in the HEPA filter, allowing only clean air to be passed through the top vents.
