Product review (2 stars): Holds up but really doesn't work
I live in Colorado and the weather is very dry here (2nd to Arizona).  At first it seemed okay.  However, after a few months I realized it doesn't seem to wick well in my Sunbeam humidifier.  With the original filter, I used to fill my reservoir every other day.  With this one I can go a week.  I often flip the filter over to get better wicking for that night but even then the top of the filter (more than 50%) is dry the next morning.  I wake up with a dry mouth now.
