Product review (1 stars): Junk filter. Water unfit to drink.
This is the second time I have ordered and used this item, and it will definitely be the last. The suggested 4 gallons to flush this filter is a joke, as I'm seeing particles floating in the water despite running 20+ gallons through the new filter. I even retrieved the old filter from the trash and cut it open to have a look inside. Maybe the surrounding fiber material is to blame, I don't know. What I do know is that it is NOT air in my water. This stuff floats to the top very slowly and will form a layer of film that can be seen in good lighting. Granted I expect it to eventually clear up like the first one did, but why buy a new filter only to be forced to use 10% of it and waste so much water in the process. I also ran a clear glass of water out of my faucet and tossed in some ice made with this new filter. As the ice melts you can see this stuff being released into the water, making it glisten.

Update: It has been a couple days and even more water has been ran through this filter, yet it continues to be unfit to drink. I uploaded two more pictures. One is of the junk floating in the water after filling the glass, the other is after the glass has sat for a while and the junk has floated to the top. You can see it swirled at the top where I picked up the glass and turned to face the light.
