Looks like you’re in the market for a HoMedics humidifier, and you’re wondering if you need to add a filter or a demineralization cartridge to the mix. Let me tell ya, as an HVAC pro with more experience than a coyote has fleas, I can give you the straight scoop on these products.
Does A Homedics Humidifier Need Filters?
Currently, all models of HoMedics humidifiers are ultrasonic. Ultrasonic humidifiers work differently than other types of humidifiers. Instead of heating up water to create steam or using a wick to draw water into the air, ultrasonic humidifiers use high-frequency vibrations to break up water into tiny droplets dispersed into the air as a cool mist.

Because ultrasonic humidifiers don’t use heat or a wick, they don’t create the same kind of mineral buildup or impurities that can clog up other types of humidifiers. That means that, in general, ultrasonic humidifiers don’t necessarily need filters to be replaced. However, some models come with filters as an optional accessory or as part of a built-in filtration system from dust and dirt.
Now, that’s not to say that ultrasonic humidifiers are perfect. Depending on the quality of your water, you may still experience some mineral buildup or impurities over time. But overall, ultrasonic humidifiers are a great option if you’re looking for a low-maintenance, easy-to-use humidifier that doesn’t require a lot of extra fuss or bother.

Does It Need A Homedics Humidifier Demineralization Cartridge

Demineralization cartridges, also known as water treatment cartridges, are a nifty little invention that can help reduce the buildup of mineral deposits in your HoMedics humidifier. Depending on where you live, the water in your area may contain many minerals and impurities, which can build up over time and clog up your humidifier. This can not only make your humidifier less effective, but it can also lead to icky stuff like mold and bacteria growth.
That’s where demineralization cartridges come in. These little critters are designed to filter mineral deposits and impurities from the water before it gets vaporized into the air. This can help prolong the life of your humidifier and improve the quality of the air you’re breathing.
Not all HoMedics humidifiers come with them, so you may need to purchase them separately. And depending on the specific model of your humidifier, you may need to replace the humidifier cartridge every so often. But trust me, keeping your humidifier running smooth like a baby’s bottom is worth it.
They are a handy tool for keeping your HoMedics humidifier in tip-top shape, especially if you live in an area with hard water or lots of mineral buildup. Read the instructions carefully and follow the manufacturer’s recommendations for replacing the cartridge.
How Often Should You Order, Purchase And Replace The Demineralization Cartridge?
According to HoMedics, you should replace these every 30-40 fillings. That should be enough to keep everything good and clean.
You can get a reasonably cheap 4-pack of replacement cartridges on Amazon here. And if you want to save money in the long run, you can also get a 12-pack or 20-pack.
Conclusion
Whether you’re in the market for a filter for HoMedics humidifier or a seasoned user, understanding the role of humidifier filters and demineralization cartridges is critical to keeping your humidifier running smoothly and effectively for your own personal care.
Depending on the specific model of your ultrasonic humidifier and the water quality in your area, you may need to use a filter or a demineralization cartridge to reduce mineral buildup and improve air quality.
Ultrasonic humidifiers, which use high-frequency vibrations to disperse a cool mist, may require more filters than other humidifier products. However, some models do still offer optional or built-in filtration systems.
