Air-O-Swiss AOS 1355N Air Washer


AOS1355N Air WasherNature and technology meet...

 Over 50 million allergy and asthma suffers in the United States can attest to the fact that it is much easier on their symptoms after a good rainfall.  That is because rain is responsible for naturally cleansing the air of airborne contaminants like dust, pollen and mold spores.

 You can expect the same performance from the AOS 1355 Air Washer.  Its ultra-quiet fan draws in the dry, dirty air from your room, washing and humidifying it as it passes through twenty-two filtration discs.  The purified air is naturally humidified and returned to your environment - a noticeable change even if you don't suffer from asthma or allergies.

 The AOS 1355 is small, effective, and stylish.   Whether you are looking to wash the air in your home, office, apartment, or dorm room, the Air Washer is ideal for removing airborne allergens like dust, pollen, and mold spores.
