Air-O-Swiss AOS 2071 Air Purifier

AOS2071 Air PurifierThe AOS2071 combines dual filtration with humidification...

With the AOS 2071 quietly working away, you are guaranteed a healthy room, whether you use it in your home or office. Ideal for rooms up to 540 square feet, it provides the purest air by removing both visible and microscopic contaminants.  This level of purification is attained through the implementation of dual HEPA filters as well as an integrated active carbon filter.  Together, these features promote a healthy room climate where allergy sufferers, in particular, can breathe easier.

The AOS 2071 then takes the air purification process one step further.   This is the only HEPA filter system on the market that also optimizes air humidity by complementing the filtration procedure with a hygienic evaporative humidifier.

Combined with a fragrance capsule for releasing essential oils into the room, your air will not only be purified, but will also smell fresh and clean.

The AOS 2071 is compact, stylish, and extremely effective.  Whether you are looking to purify the air in your home, office, apartment, or dorm room, the Portable Air Purifier and Humidifier is ideal for removing airborne allergens like dust, pollen, and mold spores as well as bacteria, viruses, and odors from tobacco smoke.

Active carbon filter eliminates harmful fumes like ozone and formaldehyde and odors from tobacco smoke, animals and cooking.
