Review: Doesn't Smell Like Fish - I was reluctant to buy these filters beacuse of the reviews complaining that they smelled like fish. Apparently these people haven't smelled fish before because these filters smell nothing like fish to me and I grew up on a lake. There is a definite odor that I noticed when I first installed the filters, but it was more akin to an odor of a t-shirt that hadn't been washed before coming from wherever it was made. It's hard to explain, but it's sort of a sterile manufacturing type smell. Not off-putting at all and kind of faint, but certainly noticeable. That said, it's not an odor that bothers me in the least (it sort of notifies me that the humidifier is on) and I haven't seen any white powder since using the filters. The downside of course is the cost, but don't let the "fish odor" reviews deter you. Anyone that thinks these filters smell like fish are either full of fish or have never smelled a fish.
Review: Good add on - So glad they make these to go with the humidifier. We have very hard water and it will help to extend the life of the humidifier greatly. They are easy to pop in. Do not affect the output of the humidifier at all. They work great. A little expensive.

## Features

- Extraordinarily Efficient Purification: DREO's three-layer ion exchange resin filtration system ensures a larger contact area with water, helping to remove calcium and magnesium ions, fully purifying every drop of water, and bringing you healthier humidification.
- Ready for a Healthier Humidification Journey: By reducing water hardness and the formation of PM2.5 particles, the DREO cartridge helps you maintain a healthy pH balance of the skin during humidification and strengthens the skin's barrier against bacteria and infections, protecting every inch of your skin, while protecting your respiratory tract.
- Less White Dust, Less Cleaning to Make: The demineralization cartridge filters hard water, effectively preventing the generation of scale and white dust, avoiding the impact on your furniture, while making daily cleaning and maintenance easier.
- Optimize Your Humidifier: The demineralization cartridge allows the humidifier to work more efficiently and for longer, by slowing down limescale buildup on the base components and improving humidification efficiency and comfort.
- Save More Money, Live More: A single cartridge can purify up to 40 gallons of water, (about a month depending on the quality of your water), you can easily see the remaining cartridge life and receive smart cleaning reminders with the DREO app.

### ⭐⭐⭐⭐⭐ Doesn't Smell Like Fish
*by C***S on February 29, 2024*

I was reluctant to buy these filters beacuse of the reviews complaining that they smelled like fish. Apparently these people haven't smelled fish before because these filters smell nothing like fish to me and I grew up on a lake. There is a definite odor that I noticed when I first installed the filters, but it was more akin to an odor of a t-shirt that hadn't been washed before coming from wherever it was made.

### ⭐⭐⭐⭐⭐ Good add on
*by M***E on December 14, 2025*

So glad they make these to go with the humidifier. We have very hard water and it will help to extend the life of the humidifier greatly. They are easy to pop in. Do not affect the output of the humidifier at all. They work great. A little expensive.

### ⭐⭐⭐⭐ It works well with hard water.
*by T***T on January 22, 2026*

I have had big issues with using hard water. These helped to the point I don't need to buy distilled water any more. There is still some hard water residue in my humidifier, but the improvement is huge and there is no white dust in the room so far.
