*by B***N on 3 November 2025*

This stuff really helps keep my humidifier from smelling funky. I just add a little each time I fill it, and it wroks well to stop any build-up or slime. The bactireostatic formula seems to do what it’s supposed to, and my water stays fresher longer. Just check out the image. I haven't seen it clean like this in a while. Only reason I gave 4 stars instead of 5 is because I wish the bottle had a smaller spout for easier pouring. Still, it’s been great overall andhelps my humidifier clean and run smoothly without much effort. Must add for a kids room to keep them healthy!
