PureGuardianFLTDC20 Humidifier Demineralization Filter, Cartridge #2, 700 Hrs. Run Time, Prevents Release of Minerals Into Air, Fights White Dust, Easy Application to PureGuardian Humidifier

It works great. Easy to use.

seems to help cut down on the gunk that builds up in humidifiers

This filter costs about a quarter of what an entire humidifier costs. Definitely way too high.

I read reviews where people experienced white dust when using their ultrasonic humidifiers. This product offers a solution. I used it all winter, and experienced no additional dust.

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!

Works as expected, however still do get some whiteness 2the output, but not enough 2 leave residue on anything.

Peace of mind knowing the humidifier is producing clean mist inside for pets and me. Very happy with it.

This works decent to prevent the white dust the humidifier makes. The water in Phoenix is so hard that not much helps the water. This helped, but didn’t fully prevent the white dust.

On my instruction manual, it didn't have where to install this on my humidifier. Very frustrating. I sent an email to the company that makes the humidifier I purchased as it stated to use this filter. Before I received a response I found to put it at the bottom of the container not at the area where the water is filled

I haven't had this filter for even a month and already it started to create more white dust it doesn't work at all maybe for 2 and 1/2 weeks or so and then that's it just say I've been wiping the white dust everywhere it's ridiculous. Someone suggested soaking the filter in the salted water I don't know if that would work I might be willing to try it but if it if it's not that it's this is really not a very good product at all might have to look elsewhere for a new humidifier cuz I think I'm still under the warranty that I can return the humidifier

Awesome filters, we get our water from the mighty Bow River and water is hard enough to walk on! Soon as we notice a fine dust film on lower cabinets it’s time to change. Now with auto re-ordering we don’t have to wait for this to happen. Buy buy buy Dust!😂

Although there are other reviews that are not totally happy with this product - I am, TOTALLY happy with it. My furniture are all covered in professionally covered plastic - due to the fact that I have 3 feral cats, who I cannot trust not to pee or tear apart my upholstered furniture. I have found this product to be VERY effective in almost elimination the dreaded WHITE dust. Keep in mind, you cannot expect this product to work efficiently in a very large room. My room with the humidifier using this product is 15 long by 12 and 15 wide depending on whether you're measuring the room from the open concept dinning room or not. - I highly recommend this product. A TIP that I received from the makers of the humidifier: run the FLTDC20 under warm water before installing it in your humidifier. Works wonders!

Bought it for the first time, and I am really pleased with it. No white powder landing on furniture since we started using it which has been about a week and a half. Without it, the white powder was almost immediate.
