Helps the white dust issue, but doesn’t solve it....
GermanTranslator—February 23, 2021
Prior to getting this filter we had fine white dust everywhere in our house, including a white film on the windows. Then we decided to try this filter for our humidifier, and it has helped, but we still have a thinner coat of dust on the furniture and tile floors, and a thinner film on all the windows. Can’t wait until we don’t need a humidifier anymore! Read more

Seems to be working -- no apparent mineral snow
Paige Bucherschrank—November 9, 2019
The cartridge seems to be working good considering that I am using tap water that has so many minerals that it leaves deposits that look like sidewalk salt on drinking glasses and such. The humidifier (we have the H1250) was used constantly all winter with no problem. But I am planning to get a new cartridge for this winter. Read more

It doesn't last very long and I don't like the humidifier
fishyks—March 28, 2016
I think it doesn't the filter doesn't last very long. Our city water is very hard and the humidifier coats the whole office with white crystal stuff. I was hoping that this filter would last, but no my office is full of that white stuff again. It even goes all the way into to the copy machine, you can pull out a cartridge and even that has the white crystals on it. Read more

Zero dust from my humidifier

Good but not essential
WW—April 4, 2018
This is a good product if you have hard water. It lasts for a year if you don't refill your humidifier every night. I did take a star off simply because there's still white powder in my daughter's room. I didn't have any trouble installing it and it does last for a very long time. Read more
