Product review (5 stars): Humidifier bacteriostst solution by Sunbeam
The ingredients is the same as the more expensive brand I'd been using. Cleaning my unit is much easier when using the solution, even the small unit that doesn't have the wick filter. I feel more comfortable cleaning the unit weekly instead of daily when I can't always get to it. There isn't any scent or odor that I can detect. A little goes a long way.
