Protec Humidifier Cleaning Fish, 30-Day Tank Cleaner, Single

The film that builds up inside a humidifier tank is the reason the mist starts to smell after a few weeks. This is the simplest fix there is: a small plastic fish that you drop in the water and leave there.

It releases a treatment that stops slime forming on the tank walls, and one lasts about 30 days. There is nothing to measure, no chemicals to handle, and it works in most cool mist, warm mist and ultrasonic machines as well as steam vaporizers.

This keeps the tank clean between washes. It does not remove mineral scale that has already formed — for chalky white buildup you want a descaler.
