Genuine Air-O-Swiss A200 Replacement Hydro Cell is compatible with virtually all Air-O-Swiss Humidifiers, ¹ including the AOS 7135 Digital Warm & Cool Mist Ultrasonic Humidifier sold by National Allergy. The Hydro Cell replaces the discontinued AOS 7017 Hydro Stick, and its discontinued predecessor, the Ionic Silver Stick.
The Hydro Cell contains activated carbon to keep your humidifier's water at its freshest between recommended cleanings. The Hydro Cell removes impurities, heavy metals, pesticides, and odor-causing chemicals from the humidifier's water. The cell's plastic housing is additionally treated with Ag+ Ionic Silver technology to inhibit microbial growth on the surface and prevent the growth of odor-causing chemicals. Hydro Cell activates as soon as it comes in contact with water, and so it is always working, even if your humidifier is turned off.
The A200 Hydro Cell comes in a 2-pack. Each cell lasts for approximately 1-2 months, depending on water quality.
|¹||The A200 Hydro Cell is not compatible with the Air-O-Swiss AOS 7146 Travel Humidifier or the AOS S450 Steam Humidifier.|
