Demineralization Cartridge 3-Pack for Humidifiers, Compatible with Dreo Humidifiers HM512S/713/713S, Prevent Mineral Build-up, Filter Hard Water, Eliminate White Dust

I had been using wicking filter humidifiers for years because I had the issue of the “white dust” film that these types of humidifiers leave. The dust was a pain because it doesn’t just quickly wipe off like normal dust but needs to be wiped off with effort. Winter came and I needed a new humidifier but the wicking filters are getting quite expensive. I ran the humidifier for about a week before these filters arrived and I had to clean the white dust off most everything in the room. I had my doubts to how much of a difference these filters would make but was impressed. I haven’t had any white dust even on the humidifier itself, yet anything else in the room. The price of 1 wicking filter is about equivalent to the 3-pack of these filters. I would highly recommend them for anyone who is having issues with the white dust and even someone using a wicking filter humidifier to change because the cost is 1/3. You get 3 months approximately for the approximate cost of 1 month for a wicking filter.

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.

Those filters prevent white dust from being spread around by the humidifier. There are very high quality and do not feel cheap at all.

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.
