Helps prevent the release of minerals (white dust) into the air.
The decalcification cartridge is easy to use. Simply screw the cartridge into the humidifier tank to help reduce the release of minerals (white dust) into the air.
How Often will I need to replace this cartridger? Approximately every 1000 hours of use or about 260 gallons of water depending on the condition of water you are using in the product.

I use my Guardian practically every other night. High attitude, low humidity area. A big help for my sinuses!! However, even with the filter, the water comes out white so it's hard to tell how well it works. My reading glasses have a white film on them in the a.m. so I don't know. But I keep using the filters.
Cartridge seems to work. Don't know how long it will be effective.
Works as advertised. Very satisfied with this product.
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.
This product is expensive and worth every penny! I live in Canada, so the shipping and exchange rate was crippling. The bottom line is...it works, no more white dust.

Works okay... but needs to be changed almost weekly.
Works well at first but after a week or so the mineral dust it's supposed to control gets progressively worse. Needs to be changed much more frequently than recommended in the directions.

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.

No more white dust!
I was using a water treatment for my humidifier and was still getting a white film all over my mirrors and furniture. I have not yet tried this filter on its own - without the water treatment - but with both I am not getting any more white dust. Sounds like lots of other reviewers are not having any success with this filter but I am glad that I gave it a shot because the white film is completely gone. I will update my review once I have tried it without the water treatment.

White dust not eliminated, but better.
While the white dust created by the humidifier isn't eliminated, it is drastically decreased. It now takes a week to make my furniture as white as it used to in one day.

Eliminates white dust build up and seems to push through the moisture easier. Fits perfectly within the lid. Well worth the money.
This filter is exactly the one I needed. The price was good and the service great. It works very well.

Stops white dust produced by humidifiers. White dust is produced from the minerals in water and is not good to breathe.
I really like this product, it has helped greatly with the issues that we were having with our water clogging the humidifier up.

These are good filters for our (filterless) humidifier. There is still a bit of white residue around in the morning but not nearly as much as before the filter. Thank you!

This filter is easy to install
This filter fits my Guardian humidifier easily and is reasonably priced. The combo of this filter and the humidifier is wonderful. No white dust anywhere.

Use of Puregaurdian FLTDC Humidifier Decalification Filter with Tap Water Results in Minimal Deposit Issues
I purchased this product for use in a Puregaurdian humidifier which has operated continuously using "hard" well water. This humidifier utilizes a vibrating disc to produce either warm or cool water vapor. Calcium buildup on both the functional disc and the internal surfaces of the tank and base of the unit has been minimal, being second only to the results obtained from using distilled water. Upon filling the unit, any deposits are easily washed away. As a result of using the filter, the cost of filling the unit is greatly reduced, and the effectiveness of the humidifier is maximized.

Does the job
I would not run a humidifier without one of these. Worked very well for about 9 months and then needed replacing. Very satisfied.
