Boneco Air O Swiss Compatible Ultrasonic & Steam Humidifier Demineralization Cartridge

These cartridges are designed to remove minerals from your tap water before it is dispersed into the air. This process effectively prevents the release of 'white dust'—the fine, chalky mineral residue often left behind by ultrasonic humidifiers when using hard water.

This cartridge is designed as a compatible replacement for the AquaPro A250 filter. It works with most Boneco and Air-O-Swiss ultrasonic and steam humidifiers that utilize this specific filter style.

Each cartridge typically lasts between 2 and 3 months, depending on the hardness of your water and how frequently you run your humidifier. We recommend replacing them as soon as you notice white dust reappearing or if the filter housing shows signs of heavy mineral buildup.

No, these cartridges are single-use items. Once the filter media has reached its capacity for mineral absorption, it cannot be cleaned or recharged and should be replaced with a fresh unit.

No, this cartridge is specifically engineered for demineralization to reduce mineral buildup and white dust. It does not contain antimicrobial treatments or carbon media for odor reduction.
