Product review (1 stars): I hate these filters
I don't write a lot of reviews but felt it was absolutely necessary to WARN anyone about this filter.  First of all, it doesn't last.  It has started falling apart after 2 weeks in my humidifier.  MORE IMPORTANTLY, there is a VERY SHARP metal piece that goes all around the filter.  It is razor blade sharp.  Why it is there, I'm not sure, but I cut my finger badly on it.  I hate these filters!!!!!  I took the filter out of the box just to take this picture and cut myself AGAIN!!!!
