DREO Demineralization Cartridge 3-Pack for Humidifiers, Compatible with Dreo Humidifiers HM311/311S/524/524S, Prevent Mineral Build-up, Filter Hard Water, Eliminate White Dust

I purchase a Dreo humidifier and I bought these demineralization cartridges to use along with it. The Dreo is great - so easy and efficient, but when you add these to it, it becomes a beast. They work! I am on 300+ hrs and these 100% prolong the cleaning and the life of the unit. I also purchased the water filter ones so that I can alternate. Definitely one of my best purchases - my machine is not slimy or yellow. No gunk. No scaling. Easy to replace - you push it in, that is all. I want the mist in my home to be healthy and I feel much better about it with one of these in my machine. They are definitely worth purchasing and I will keep them stocked.

Works well to use with hard water sources. I still noticed white dust, however. Easy to install with no tools. Filters last about a month. Not too costly.

Works perfectly. I use them filter my drinking and ironing water.

WARNING! DO NOT BUY THESE. For whatever reason, they breakdown after a few uses and the granules inside of them get stuck into the stopper, leaving it open, which causes the reservoir to overflow. It has flooded and damaged my furniture and my flooring twice. Since I bought the three pack, I decided that maybe just one of them was bad and installed the new one. That one lasted only one week before it caused the same problem. Inside of the reservoir once I remove this filter, you can see the pink granules that are all over and falling out out of the cartridge. These get stuck in the stopper. I am going to write to the manufacturer and demand a refund for this and for the humidifier. They are a pretty good company as far as replacement goes. But so far the quality control seems to be not that great as I also own one of their smart fans that has a screen that died shortly after use. They sent a replacement fan, but the other fan still works, I just use it with voice command and the app instead of the actual screen.

This has significantly cut down on white dust. I’ve tried others, but nothing else came close.

Fit and work perfectly... wish they were cheaper than store

Exactly as described by the seller.

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!

Die Dreo Entmineralisierungskartuschen im 3er-Pack erfüllen ihren Zweck absolut zuverlässig. Seit ich sie in meinem Luftbefeuchter verwende, hat sich das Problem mit weißem Staub deutlich reduziert. Gerade bei hartem Wasser merkt man den Unterschied schnell. Die Kartuschen lassen sich unkompliziert einsetzen und passen perfekt in die kompatiblen Dreo-Modelle. Es tropft nichts, alles sitzt fest und funktioniert sofort ohne zusätzliche Einstellungen. Auch in Bezug auf Mineralablagerungen im Gerät selbst habe ich eine Verbesserung festgestellt. Der Luftbefeuchter bleibt sauberer und wirkt insgesamt wartungsärmer. Das 3er-Pack ist praktisch, da man direkt Ersatz auf Vorrat hat. Fazit: Sehr sinnvolle Ergänzung für Dreo Luftbefeuchter, besonders bei hartem Wasser. Reduziert weißen Staub deutlich und sorgt für saubere Befeuchtung. Klare Kaufempfehlung.

Great filters making a visible change to using the humidifier! They remove the need to clean the device pretty much daily, which is an absolute relief! I’m still on the first one but I’m glad tracking the filter’s longevity in the app is a great convenience!

Lo he comprado para el humidificador ya que este filtro pide la app. Pero dentro del aparato no he encontrado ningún filtro
