"These humidifier drops work really well, I was pleasantly surprised. Really help keep the humidifier clean. However out of no where the bottle clogged. I have stuck a sharp object down trying to unclog it to no avail. Not sure what happened but now half the bottle is wasted."

"This keeps your humidifier cleaner longer and the applicator is perfect for using only a few drops at a time. There is no staining. Must buy for my plant humidifiers"

"I barely leave reviews, but this product actually works well so I wanted to give a shout out. I put three drops into my daughter's humidifier every night and mold rarely forms. It went from mold being a daily problem to me maybe having to clean the humidifier further once a month or so. I'm also still on my first bottle so one bottle lasts months and months!"
