Room Size: Cleans up to 375 sq ft. Specially designed for allergy and asthma sufferers. Highly effective specialized military-grade carbon cloth for superior particulate filtration. Available in black, white, sandstone, and midnight blue. ----- The Allergy Machine Junior HM205 is the smaller version of Austin Air's Allergy Machine air cleaner.  It offers the same filtration but instead of 6 lbs of granular carbon, a lightweight carbon cloth is used to create HEGA filtration - High Efficiency Gas Absorption. The carbon cloth does not release carbon dust when air passes through it, allowing it to be placed after the True HEPA filter.  The smaller size makes it very portable and easy to fit in tight spaces. Wheels are not included, but are an optional add-on item. 360° 4-Stage Filtering System: Austin Air's 360° design draws air into all sides of the air purifier, passing it through first an outer pre-filter and then a main filter that combines three additional stages of filtration: STAGE 1: Large Particle PermaFilt Pre-Filter (wraps around main filter)Cleanable re-usable prefilter traps large particles easily seen by the naked eye (dust, hair, lint, pet dander, etc) while prolonging the life of the main filter. Easy to maintain - simply vacuum clean monthly from the outside of the unit.  STAGE 2: Medium Particle Pre-FilterRemoves additional small to medium sized particles (mold spores, pollen). STAGE 3: 30 sq ft Certified True HEPA filter mediaMedical-grade True HEPA pleated filter traps up to 99.97% of particles as small as 0.3 microns that pass through the filter. STAGE 4: HEGA Carbon ClothLightweight HEGA cloth (High Efficiency Gas Adsorption) reduces chemical pollutants, gases, and odors.
