Boneco Air O Swiss Ultrasonic & Steam Humidifier Demineralization Cartridge

These cartridges are designed to be compatible with the HFT600 series of Boneco and Air O Swiss ultrasonic and steam humidifiers. We recommend checking your humidifier's manual or current filter housing to confirm it uses this specific screw-on cartridge style.

Each cartridge typically lasts between 2 and 3 months, depending on your local water hardness and daily usage. You should replace the cartridge when you notice white dust beginning to accumulate around the unit or if you see visible mineral buildup inside the tank.

This cartridge is specifically engineered to reduce mineral content like calcium and lime, which prevents the 'white dust' often associated with hard water. While it significantly improves water quality for humidification, it is not a water purification filter intended to make water potable.

Not at all. The installation is straightforward: simply unscrew the old cartridge from your humidifier tank and screw the new one into place. No tools are required.

Ultrasonic humidifiers work by vibrating water into a fine mist. If your tap water is 'hard' (high in minerals), those minerals are dispersed into the air along with the moisture, creating a fine white dust on your furniture and surfaces. This cartridge traps those minerals before they can be misted into your room.
