DREO Clean Mist Cartridge 3-Pack for Humidifiers, Compatible with Dreo Humidifiers HM311/311S/524/524S/306, Reduce Contaminants Build-up, Healthier Mist, Easier Cleaning

I am beyond impressed with the Dreo Demineralization Cartridge 3-Pack! These cartridges work wonders in preventing mineral build-up and eliminating white dust, making my humidifier run more efficiently and keeping the air in my home fresh and clean. The three-layer filtration system ensures that hard water contaminants are filtered out, resulting in a healthier mist—perfect for those with sensitive sinuses or respiratory concerns. Installation was effortless, and I love that each cartridge lasts up to 150 liters of water, meaning fewer replacements and more convenience. The Dreo app integration is a fantastic bonus, allowing me to monitor the cartridge lifespan with ease. If you're looking to extend the life of your humidifier and improve air quality, this is an absolute game-changer! Highly recommend!

Fit my humidifier perfectly and I have not seen any mineral dust since I installed it.

When I initially bought the dreo room humidifier it was mentioned that I could use a demineralization cartridge or a clean air one because I have soft water I went with the clean Air filter when I initially got the unit it had like a little lid {see pix} where the cartridges pops in the place it actually works better without these in my own opinion... My water is different I have soft water my room's different probably than most people I do recommend that you get these for safe measure but I don't know why you would want to sell a demineralization cartridge if it blows out white powder according to what others have said in their reviews that it blows white dust everywhere that did not happen to me because I did not pick the demineralization one I couldn't make no sense of it so I called the actual company but I purchased them off Amazon three days of using the filter my machine had orange gunk in it prior to that I could run it for days with no gunk using regular soft tap water & no filter now I don't know if I wasted my money or if I'm best just to put the little cap that it came with back on after I going to give these filters a second chance after a full clean of the unit because if it's a filter mold got to it quick... For me it ran better with jus the little cap that came with it you don't have to clean these cartridges but on the initial install I was told by the company when I registered with them to make sure you rinse them well before you put them in your machine So the ease of cleaning those was pretty easy the fit went very well jus pops in the unit itself is top shelf quality I run mine on level 3 to get the most of the humidity due to my lung issues it makes the temperature of my room a little bit cooler & much easier to breathe with lung conditions the humidity level the smart part of the machine the base unit lets me know by digital readout how the humidity level is fairing make sure to read the directions at the moment I can't tell you how long these filters last but I do remember it was a good amount of time I don't think I will buy these anymore I will come back to update if the orange mold keeps showing up then I may not use these ever again and just use the cap... I was cleaning it ever 3 days as it runs nonstop in my room so I don't know if these are good idea or not many consumers has stated in reviews on the unit that one cartridge of certain flavor/demineralization will put white residue all over the area my experience with these filters is after 3 days I had to tear it down which is no easy task & clean out the gunk so I'm not breathing that orange mold let alone the ick but if you have hard water it speaks & acts different as in said above 3 for $18 is not bad it's the same price thru dreo or dreo store on Amazon

Seems to work as advertised. Not sure what difference is between the cartridges listed for "clean mist" and the other cartridges (that look identical) that are described as "demineralization". Is there really any difference?

I bought these clean mist filters to go with my DREO humidifier. They are easy to install and since each filer lasts 3-4 months, this one box should last almost a year, so they are very economical.

For its price, I expected this to work and last longer. It worked for a few days but after that, white dusts everywhere. Before buying, you have to know that it only lasts for a total of 12 hours of use. You need to replace it after that and with us having 3 humidity at home, that's extremely pricey. If you are someone planning to use your humidifier everyday, I would suggest looking elsewhere.

This humidifier filter works perfectly! It absorbs water evenly and keeps the air clean and fresh. My humidifier runs smoother and the mist quality is much better. Great replacement filter—totally worth it.”

Product is as advertised. Easy to install in our humidifier. Works great with and without essential oils. With the filter you can use regular tap water instead of filtered water
