Product review (1 stars): BAD QUALITY
We found to be very poor quality compared to the genuine Idyllis filters we usually buy.  They were so brittle that one was already broken in half when we took it out of the box.  Maybe it was a fluke, but after looking at these, I'm back to the genuine filters for my brand.  Better to pay a little bit more and get something that holds up.  Only good thing was the Amazon return process was very easy.
