Compare Air O Swiss Humidifiers

From our perspective Air-O-Swiss Humidifiers have everything you could possibly want in a humidifier. They last longer than any other humidifier we have tested, they are easy to clean, a mineral cartridge keeps down white dust, and a unique Hydro Stick keeps the humidifier clean and fresh longer. We rate the Air-O-Swiss 7144 as our "Best in Class" cool and warm mist humidifier because of its quiet operation. For a combination humidifier and air purifier in one, the Air-O-Swiss 2055A Air Washer Humidifier can't be beat. We also offer all Air-O-Swiss humidifier replacement filters and cartridges.
