One of the best air purifiers on the market, the Bedroom Machine HEPA filter air purifier is equipped with a Pre-Filter that removes large and easily seen particles such as dust, hair, and pet dander. It also has a Medium Filter that gets rid of small to medium size particles including molds, spores, and pollen. The third stage of filtration is the Activated Carbon and Zeolite Filter which removes chemicals, gases, and odors for a cleaner and fresher smelling air. The fourth stage is the medical-grade HEPA filter that effectively removes 99% of particles larger than 0.3 microns and 95% of airborne viruses that are 0.1 microns in size. The final stage of air purification is the military-grade HEGA Carbon Cloth which provides an extremely large surface area for the absorption of chemicals, gases, viruses, and bacteria. The HEGA filter is also known to be more efficient than the granular activated carbon and was designed to protect people from biological warfare
