The Rabbit Air BioGS removes a wide variety of allergens and contaminants from the air, including dust, pollens, dander, odors, mold, and chemical vapors. Its HEPA filter traps and destroys a host of common allergens, such as pet dander, dust mites, and pollen. Each filter can last up to three years, based on 12 hours of daily operation, and won't create secondary pollution like conventional HEPA air cleaners. Our Signature HEPA filter traps airborne allergens and contaminants down to 0.3 microns in size 99.97 percent of the time and also includes a medium filter to boost efficiency and increase HEPA filter lifespan. The BioGS features a permanent pre-filter to help eliminate large airborne particles as well as a washable Charcoal Based Activated Carbon Filter for odor and chemical absorption. With its energy efficient design, the BioGS is safe and inexpensive to operate, emitting no ozone and only consuming 33 watts at turbo speed and seven watts at silent speed. The BioGS also features an inverter control and auto air quality monitoring, which means the unit can operate at five different speeds and it won't run at a higher speed than necessary. Ideal for home or small office use, this air purifier covers up to 600 square feet, based on two air changes per hour. It's also completely silent at low speed, and creates a minimum amount of distracting noises.
