They work amazing, keeps my humidifier clean and easy to maintain! They were also very responsive when I had an issue with my order and quick to send me a new one, I just called them up on the phone and it was all addressed very efficiently. Highly recommend, they care about their customers.

This stuff works! Now, I will say that I started using these drops at the same time as I got the fish with the balls in them, BUUUUUUUUT the funky smell in my humidifier is gone!! I had just deep cleaned my humidifier and within a few days it was smelly again. I put these drops and the fish in, and the smell is gone!!! I’m so happy I found this!!

I notice a lack of slime in my humidifier when I use this item, but it doesn't cut down the Calcium in my water. Maybe it's not supposed to? I notice that the tiny hole where the liquid comes out gets clogged or something, so I've had to actually cut the end off after some use.

I live in a part of the country where the water is very high in minerals. I have to use bottled water for drinking and also for my humidifier. Using these drops in the water completes the process and I feel like the water is clean. There is no residue on the inside of the humidifier, although it still needs regular cleaning on occasion. I'm very pleased with this product and think it is a good value for the money.

This stuff works amazingly. My apartment’s tap water is nasty and even after filtering it, it doesn’t take long to start growing a pink slime mold in my humidifier. I used to have to clean the humidifier every couple of days.Once I started using these drops, no mold ever grew. I was able to let it go a couple of weeks before cleaning it and even then it didn’t seem like it needed it. There was no mold and no smell. I still clean it every couple of weeks just to be safe but this stuff really keeps mold from growing.The most amazing part is in Minnesota we’ve been having a usually warm winter and my humidity has actually been staying pretty high so I haven’t used my humidifier in over a month at this point. I just remembered that the water has been sitting in it for probably six weeks now and I was scared of what I would find growing in it. Nothing. Perfectly clear, the sides were perfectly white and no smell. It’s so nice to know that I can forget about it and not have a nasty science experiment growing.

I’ve been using these for a few weeks now. There is a sediment in the mature that makes it impossible to get the drops out after time. I have tried shaking it and nothing works. 3 stars since I think the solution is actually pretty good at keeping the humidifier clean! Just wish it was easier to get out of the bottle

Only got to use for a short time because it got hot too early, but seems to work well

Does it's job, but pricey
