Ratings & Reviews+

PureGuardian® FLTDC Humidifier Demineralization Cartridge is rated 4.3 out of 5 by 6.
Rated 4 out of 5 by from I'd give it a B+ It hasn't totally eliminated the white residue but it's probably 80% improved. It takes a few days to notice the difference, since I think the filter needs some priming. Definitely glad I got it and if it lasts at least 6 months, it's well worth the price.

Rated 5 out of 5 by from Perfect Fit - Easy to use This filter was very easy to install. On first use, I filled tank and placed back on unit and did not turn back on until the water filled filter. You can tell it's filled when air bubbles stop.

Rated 5 out of 5 by from white dust problem solved I love this humidifier. White dust is a problem with ultrasonic humidifiers, this filter does a great job on white dust. I go through 2-3 a season. I also fill the unit with Brita filtered water from the tap..

Rated 2 out of 5 by from Doesn't seem to do much I've only run a couple of tanks of water through the humidifier since adding this filter, but I can't tell much of a difference. The white dust is still appearing on the furniture and I can see a haze in the air when the sunlight comes through the window. I can only hope that it is doing some good, but it is not eliminating the white dust problem.

Rated 5 out of 5 by from Interesting Seems to work great! I wanted a decalcification tablet. Can't seem to get one. I have no idea what's going to happen when the calcium builds up around the heater.

Rated 5 out of 5 by from Does the job that it is supposed to do. I had white mineral dust all over my furniture while using my Pureguardian humidifier until I installed this filter. The filter removed much of the high mineral deposits from my well water reducing the dust significantly. I am also now using rain water, when I am able to collect it, which eliminates all the white mineral dust. The filter is expensive adding a great deal to the operating cost but I had no choice in using it. The filter has a limited life.
