Product review (4 stars): It's a filter, I assume my water is cleaner.
This is a generic substitute for a far more expensive name brand product. To date I've purchased about 3 of these. My refrigerator came with 2 name brand filters but I refuse to pay that much for the name. I've used these since my 2 freebies ran out and I can't tell the difference. That being said, there could be a difference but I just want my water to be generally clean. If I wanted it perfect I'd have a $1000 home filtration system.
