Product review (2 stars): They're ok but I won't 'Buy Again'
Perhaps I bought the wrong filters. They don't seem to standup as well as prior ones that I bought. The filters aren't rigid enough when wet to keep their shape when placed in the humidifier and after a few refills of the water tank, the filters turn yellow and brittle so not a lot of water is wicked through them. I might as well just have a fan blow over a bowl of water. I'll use these up and look for another replacement filter.
