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

Works as expected. It has drastically reduced the frequency with which I need to clean my humidifier. It’s also super cute floating around in the tank. My humidifier opens from the top, so I had no issues placing the fish inside.

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!

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.

Help keep my humidifier water clean.

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!

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.

It seems the product has quality issue because it does not last as long as the ones purchased in the past. Hopefully the future products will improve in quality. Will be shopping around until then for a similar product.

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.
