I definitely got my money's worth from this and will be purchasing more!
Review: Keeps My Humidifier Fresh, Clean, and Odor-Free! - The Protec Humidifier Cleaning Fish is a small but mighty helper for keeping my humidifier in perfect condition. I’ve been using these for over a year now, and they make a huge difference — no more slime, buildup, or musty odor in the tank! I simply drop one fish into the water tank, and it works continuously for about a month, keeping everything cleaner between deep washes. It’s especially helpful for ultrasonic and cool mist humidifiers, which can develop residue quickly. The fish keeps the water clear and fresh, and I’ve noticed less mineral buildup and fewer cleaning sessions needed. It doesn’t affect mist quality or smell, and it’s safe to use around kids and pets, which gives me peace of mind. The best part is the convenience — just replace it every 30 days, and your humidifier stays in great shape. It’s also fun that the fish comes in different colors, which makes it easy to spot in the tank. For such a low cost, this little product saves me a ton of time and keeps my humidifier performing like new. Highly recommend for anyone who uses a humidifier regularly!

## Questions & Answers

**Q: How do you clean this little fish? Do you soak in vinegar and bleach like the rest of the humidifier? Or will that damage it?**
A: Per the instructions of the user manual you only need to clean and sanitize once a week and never the fish EVER . U are not to use soap or any detergents. Just vinegar swish and wipe let sit for 20 minutes and rinse with clean water to get smell out let dry. THEN BLEACH . never together. Always always keep the manuals to products you buy and store them in a accordion folder to always refer to. The manual tells you all this and how much to use . 2 cups of vinegar solely for the scale buildup . And 1/2 tbs bleach to 1/2 of water . Never mix bleach and vinegar. You don't mix a base with an acid

**Q: What is it made out of? Is it chemical?**
A: Chris is trolling. The term he used—dihydrogen monoxide—means, literally, water. 
di (meaning two) hydrogen molecules + mono (meaning one) oxide (meaning oxygen) molecule = H2O, which is the chemical shorthand for water, which most of us are familiar with. 
“Dihydrogen monoxide parody” 
“ The dihydrogen monoxide parody involves calling water by an unfamiliar chemical name, most often "dihydrogen monoxide", and listing some of water's properties in a particularly alarming manner, such as accelerating corrosion and causing suffocation.” Wikipedia 

Don’t try to breathe the water in a humidifier (or drink it, for that matter), and you’ll be okay

**Q: Does this fish clink or make any noise if it hits the side of the tank and disturb light sleepers?**
A: The fish hardly moves unless you shake the tank, I don’t think it would make a sound louder than the blowing of the humidifier.

**Q: Can you put this in a dehumidifier? They get so scummy!**
A: That's what I was coming here to ask.  I would think it would work the same way. I can't see how it would be any different.

### ⭐⭐⭐⭐ Please improve the size!
*by D***D on January 31, 2026*

Unfortunately this doesn't fit in many humidifier tank openings (even though it would fit in the tank itself) due to the fins of the fish. I would appreciate a thinner cylinder so it was more versatile.
