Product review (2 stars): Smelly!
These filters start to smell quickly and don't last long if you want a clear filter. Every morning we open the humidifier, pull the filter out of the water to et it dry and then flip it to the other end when putting back in at night. It is too thick to dry so it starts to stink soon after putting in a new one. The original filter that was thinner and didn't have the metal was much better braise it would dry out quickly, but I can't find them anywhere.
