With environmental danger all around the world, it is up to individuals to keep the air around them safe. The Dreval HEPA 6 Stage Air Purifier was created in order to accommodate users in small spaces by retaining the same quiet but powerful qualities as the Dreval 950. The Dreval 906’s purification efficiency comes from its 6 stage process. First air enters the cold catalyst filter, which eliminates harmful gasses before the air is sent to the cellular activated carbon filter. This stage promotes decomposition of formaldehyde, benzene, ammonia, second-hand smoke, and other various odors and then passes the air to the anti-bacterial filter which removes the finer particulates, microbes, and bacterias. Next, air passes to the High-Efficiency HEPA filter which eliminates mold dust and some bacteria. Then, the Ultraviolet Germicide light capitalizes on the HEPA filters actions and rapidly kills the rest of the bacteria and viruses. Finally, anions are infused with the air before it is let free back into your now clean home.
