Product review (1 stars): 2 out of 3 were cracked
I bought these through Woot.com and found 2 of the 3 filters had cracks.  Had appliance man over to change what we thought was a bad filter base but it was the 2 new filters that were bad which he confirmed.  They have been sitting in a cabinet for a year as they are changed only every 6 months, not sure what my recourse would be.
