Boneco Demineralization Cartridge

The cartridge typically lasts about 3 months, but this depends on your local water hardness. If you notice white dust beginning to form around your humidifier or a decrease in performance, it is time to swap it out for a new one.

No, this specific cartridge (part number A451) is designed exclusively for the Boneco S200, S450, and S400 steam and warm mist models. Please verify your specific unit model number before purchasing.

No, this is a single-use, non-reusable filter. Once the ion exchange resin inside is exhausted, it cannot be cleaned or recharged and must be replaced to maintain proper mineral reduction.

While this cartridge significantly reduces mineral buildup and white dust by using ion exchange technology, the effectiveness can vary based on the mineral content of your tap water. If you have extremely hard water, you may still see minor residue, but it will be substantially less than without the filter.

Steam humidifiers boil water to create mist, which concentrates minerals found in your tap water. Using this cartridge prevents those minerals from turning into limescale inside your machine, which extends the lifespan of your appliance and keeps the mist cleaner.
