With steady use, you'll get relief from your symptoms or even eliminate them all together both during the day and while you sleep. Every minute, the system pulls in room air from all sides of the air cleaner. Air passes through a 5-stage HEPA/carbon combination filter and is blown back out into your room using the Clean Air Pocket vent. This extensive filtration system cleans your air faster and more efficiently than conventional air purifiers, which means quicker relief from your symptoms. The Bedroom Machine Air Cleaner 5-stage combination filter includes: PERMAFILT Pre-Filter: During stage 1, air passes through a cotton PERMAFILT pre-filter, which captures particles easily seen by the naked eye, such as large dust and pet dander particles. Medium Particle Filter: Next, a medium particle filter traps small- to medium-size allergens, such as mold, pollen, and dust mites. Carbon Blend Filter: Next, air moves through a 15-pound carbon and natural zeolite filter where odors, chemicals, gases, fumes, and VOCs are absorbed and locked away. Medical-Grade HEPA Filter: Air then glides through 60 square feet of true medical-grade HEPA (High Efficiency Particulate Air) material where it is scrubbed free of harmful bacteria and viruses as well as smaller pollen, mold, pet dander, dust, and ragweed particles. HEGA Carbon Filter: Lastly, a HEGA (High Efficiency Gas Absorption) filter constructed of military-grade activated carbon cloth acts as double protection against odors, gases, chemicals, and VOCs. Overall, this long-lasting combination filter eliminates 99.97% of airborne pollutants that are 0.3 microns and larger, 95% of particles that measure 0.1 micron and smaller, and more than 3,000 types of toxic gases and odors. You'll rest easy knowing that you and your family are breathing the cleanest air possible.
