Product review (1 stars): Switched from manufacturer filter and I can tell!
I've tried 2 of the 3 filters from the 3 pack, but they leave my water tasting like hose water.  As the water warms up after sitting in my glass, the hose taste becomes even more pronounced.  My long past expiration manufacturer filter left the water tasting much better than what I've experienced with these. I'm switching back to filters from the manufacturer.
