Hfunmo Demineralization Cartridge for Humidifier, Filter Replacement Compatible with HoMedics Ultrasonic Humidifier

There have been no issues with these and they work as advertised. Can’t go wrong for the price.

Easy to use to help with minerals in the humidifier. Our house gets very dry in winter and we use 2 humidifiers We haven't noticed an excessive amount of the white powder this says to help with, but one of our units had a demineralization cartridge included, but after a lot of use, probably time for a replacement. We also use a liquid additive in the water to reduce buildup, so this is a little extra precaution to keep everything running smoothly and cleanly.

Unfortunately this product has not made a difference in the white dust everywhere. Bummed it does not work.

These demineralization cartridges seems to be working pretty well so far. I've added them to all 3 of our home's humidifiers, and the amount of mineral build-up that we typically see seems to be reduced. Using them is very simple, just drop them in the humidifier's water tank and let them go to work. They seem a little pricey for what they are, but if they help to extend the life of our humidifiers, and/or the humidifier filters, then they'll easily pay for themselves in their first year of use. I like that you receive a pack of 20, so they should last us for at least a few years.Recommended.
