I got these for my river home. Due to the dampness of being near a body of water and being closed up for periods of time, mildew in closets were an issue. After getting these , even the smell in house improved. I would recommend these for anyone that has moisture in places that shouldn't be. The picture is actually in my closet at regular home and you can see they is moisture there as well. Fantastic for freshness of any enclosed area. They last several months. It really depends on how much moisture there is. I will not be without them!
