I’ve used these for a few weeks now. No more mineral dust or build up in the humidifier. I was going nuts dusting every two days. I can dust about every two weeks now. I suggest to first thoroughly clean the humidifier before using these. I plan to change out every 30 days because I run humidifiers 24/7 365 days in this very dry state. Read more

These are good to use, however, I still get residue on my vaporizer even when I use purified water. I’m sure it does take some of the mineral deposit out, but I still get quite a bit of white coated you know deposits on the top where the water comes out. It’s supposed to reduce that, but it looks like I’m in the north Pole! It’s hard to get that off even with vinegar! Read more

I've used these demineralization cartridges in two different brands of humidifiers with good results. They help prevent scale buildup and white dust from hard water. Read more

These made absolutely no difference in the white dusty film that accumulates on everything overnight. Especially noticeable on glasses and flat surfaces. I added up to 4 cartridges in the tank and still no difference. Tried water from house without softwater and still, no difference. Tried leaving cartridges in water for full day before turning on at night. Still no difference. I was hopeful but nothing worked. For me, waste of money. Read more
