Protec Humidifier Cleaning Fish, Tank Cleaner, Fights Slime & Odor, Lasts 30 ...

These are the best things I have ever found to keep our humidifiers clean all winter long! They are easy to use, just drop in water. We change them out once a month to keep it clean and very pleased with them. No more orange or green growing gunk! Just tap water and one fish and we keep the house from being too dry and prevent nose bleeds during the winter. The grandkids love to watch them. Wish they were a little cheaper but you do get what you pay for. Tried the cheaper ones and they did not hold up as these did. Will keep using every winter in every room!

I was tickled to find these as I use my humidifier nightly. Wow, these really work!!! The steam from the humidifier has a fresher smell. My humidifier does not require the degree of cleaning before I started using these. It doesn’t get as dirty. I’m so glad I found these and I highly recommend.

It helps keep odors out of the water. Its very effective. Hasn't leaked anything since buying it. Doesnt leave any residue. Very easy to use. Plus its cute.

Help a lot; easy to use and replace; keeps the tank from getting slimy as quickly. Good quality and cheap!

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 thing is amazing. Really works. Needed to clean the humidifier MUCH less frequently.

I couldn’t tell if they work or not.

Works great

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.
