Dreval HEPA 6 Stage Air Purifier D-903 purification efficiency comes from its 6 stage process:
Cold Catalyst Filter:
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.
Cellular-Activated Carbon Filter:
The cellular-activated carbon carries high efficient additives. It has an excellent absorption and dust collection abilities.
The 5-microns flter with antimicrobial agents can effciently kill bacteria in the air.
High Efficiency HEPA Filter:
The precision of the HEPA filter is 0.1-0.3 -micron. It is able to eliminate particles larger than 0.3 micron with the filtration rate of 99.97% or more. Dust, bacteria, fungi, viruses, allergens and other small and tiny particles are not able to get through the HEPA flter.
Filters are washable but should be replaced approximately once every 6-12 months depending on air quality and product usage.
