Guardian Technologies GGHS15 Aquastick Antimicrobial Humidifier Treatment, 2-Pack, Pure Guardian Humidifiers, Evaporative Humidifier Water Tanks

This product is brilliant. It keeps my humidifier clean for a very long time. No odours and no issues with the product either. Very user friendly.

Works, but I could see pink slime bacteria starting after I didn't wash the humidifier as soon as I should have. Probably would have been worse without this, though, so I'll keep buying them.

These work! I have purchased other products like this that did not work. This product does!

Bought for my husbands humidifier. I am always looking for a good option for keeping the tank and rest of the machine as clean as possible. Helps make it easier to clean and of course the much larger bonus - safe and healthy! he uses his humidifier daily.

I tell you I have not had any mold in my humidifier since I've been using one of these for the season. I used to have a problem with black mold in my humidifier cause we use a Woodstove one of these are season and I have had no black mold, kind of speaks for itself.
