Product review (1 stars): Filter became soggy and began to fall apart
I have used Aircare filters for 3 seasons, and even though we had a mild winter and I didn't have to use my humidifier as often as I did the previous years, the filter, as other reviewers have commented, became soggy and flopped over, making the humidifier do a poor job of improving the humidity in the room.  I also noticed that it was beginning to come apart with small pieces falling to the bottom of he humidifier.  Luckily, I had kept the previous year's filter and although part of it had become hard with lime, it still worked much better than my current one.

I don't know if I just got a bad filter, or if they aren't being made as well.  Very disappointed.
