Keep your Air-O-Swiss humidifier's tank fresh and free of impurities with the Air-O-Swiss AOS A200 Hydro Cell. The Air-O-Swiss Hydro Cell uses activated carbon technology to reduce the growth of odor-causing chemicals inside your humidifier and keep the inside of the tank fresh and clean. This helps you enjoy fresh, clean moisture day after day.
The Air-O-Swiss Hydro Cell replaces the Air-O-Swiss Hydro Stick and it's compatible with all Air-O-Swiss humidifiers except for the S450 Steam Humidifier.
To ensure the highest water quality in your humidifier, be sure to replace your Hydro Cell every 1 to 2 months, depending on the hardness of your water. It activates immediately once you fill your humidifier's water reservoir.
The Air-O-Swiss Hydro Cell is available in a convenient 2-pack.
