Product review (1 stars): horrible filter
I'd give this filter 0 stars if that was an option.  I use a humidifier for health reasons.  It's a necessary part of my life to have at least 45 to 50% humidity.  This filter, which I installed just yesterday, is not generating more than 35 to 38%.  This filter is so cheaply made and thin that it's totally collapsed in the humidifier.  I couldn't be more displeased.  Now, I'll have to spend extra money to buy one locally.
