Product review (1 stars): Water through these filters made us sick. Literally.
I bought this 3-pack thinking it would be a good deal. However, each of these filters caused a bad taste with the refrigerator water, and made everyone in my family who drank the water sick to their stomach, on multiple occasions. We went through all three of these filters, each of them caused the same issue.  We even tried running several gallons through to "flush it out" between filter changes; it still made us nauseous.

I replaced the filter with a bypass plug; the water immediately tasted great and no longer upsets our stomach.

Someone else posted something similar as a review for these filters, so it doesn't sound like I'm alone.
