Product review (1 stars): same rating on my water tester as the tap water.
I just bought a new home with an order refrigerator that came with it. I was hoping to use the water from the fridge for drinking rather than the zero water filter I have on the counter top. It is obviously more convenient to use water out of the refrigerator.

I ran 10 gallons of water through the filter just to be safe the water was clean and I was very disappointed when my water tester detected 026ppm contaminants in the water coming from the brand new filter. This is exactly the same rating as the water straight from my tap water. I have not used any other filter with this fridge and I don't know if the GE filters are better but I will say that the $40 Zero water filter on my counter top always test 000ppm with a new filter. It takes roughly 4months for it to detect 001ppm and id say roughly at 6 months I change it when it reads 005ppm.

I am greatly disappointed with these results.
