AIR-O-SWISS, a brand name of PLASTON AG Switzerland, develops and manufactures technologically advanced air treatment systems with exclusive Swiss design that provide top quality room air. Our line of humidifiers, air purifiers and combi systems aid your health, productivity and general well being all year long.

• Ultrasonic Humidifiers employ technology that uses high-frequency vibrations to generate micro-fine mist. Cool Mist and Dual Warm & Cool Mist models as well as digitally controlled units are available.
• Air Washers purify while they humidify. Water in conjunction with rotating discs retain and remove air-borne impurities while returning clean, properly humidified air to the room.
• Evaporators force dry air through a wet evaporator wick and release it into the room as properly humidified air. The wick also catches dust and dirt particles for added benefit.
• Air Cleaners purify the air using a dual filter system to eliminate pollen, dust, mites, smoke and even odors from a room. Allergy sufferers love our air cleaners.
• Steam Humidifiers heats the water to the boiling point. As a result, the vaporized water humidifies the room air. The steam humidifier system is the most hygenic way of air purification. 

The systems are marketed under the brand name AIR-O-SWISS (AOS).
