Protec Humidifier Cleaning Fish, Tank Cleaner, Fights Slime & Odor, Lasts 30 Days, 1 Count, Color May Vary

This little guy is so cute. I’ve named him Oscar. I didn’t realize till I read the instructions a few days after I started using it that you weren’t supposed to touch him (which I did, but I’m still here), have to wrap it in newspaper (haven’t seen any of those in a while) to discard it, etc. This scared me that it might not be safe to inhale the mist but I looked it up and apparently it is perfectly safe and does appear to keep the humidifier tank clean as a whistle though you are still supposed to clean it regularly. I definitely recommend it even though it’s a little pricey to replace each month which is recommended.

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!

This works great! Purchased in November and it lasted until January with consistent use. The fish is super easy to use, you just drop right into the humidifier and it does its thing. It keeps it clean, with no smells and is safe to use. I definitely got my money's worth from this and will be purchasing more!

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.

My humidifier has never smelled nicer, no more moldy smell. And the water is always clear. I'm off to buy another one.

We have had a standing water problem with our humidifiers with a build up of brown slime. Since we started to use Protec Cleaning Fish this problem has disappeared. It has done the job!!

Keeps the water clean but doesnt protect against mold, fyi

Oh my! I bought a humidifier and even though I keep it clean it gets a smell. I saw this and decided to try it. Oh Wow! The smell is gone! I will keep on purchasing this cute lil fish! I highly recommend this little guy!!!!!

Mantiene limpio el tanque por ser un veneno que mata bacteria y mohos. He comprobado objetivamente (con un medidor de contaminación del aire) y subjetivamente (me arde la garganta si lo tenga cercas) que contamina al aire, lo cual invalida la idea de utilizar un humidificador para mejorar la calidad del aire. Mi humidificador es en frío, quizás con un humidificador de vapor el veneno no sale, eso no lo he comprobado. Sí queda limpio el tanque, en ese sentido cumple, por eso le doy dos estrellas.
