Product review (1 stars): Worthless ripoff
I am very disappointed with this filter. This was the first time I changed the filter. I measured the water for contaminents in ppm after the change and purging the system of 2 gallons of water. The measurement was 450 exactly the same as coming out of the tap. While any measurement below 500 is acceptable to drink, I do not see any value in using this filter, and I will not drink water with a 450 measurement. As a comparison, Poland Spring water measured at 50 ppm. I called GE who was clueless regarding ppm measurements, and did not say the filter was defective. Really?
