Product review (2 stars): Water purity readings came back high
Is this product brand new, or refurbished? The package wasn't exactly sealed, but I don't know what the original package is supposed to look like. When I opened the sticky cover to the head of the filter, small white pieces of what looks like plastic could be seen.

When I plugged in the filter, and ran 4 gallons through as instructed, I tested the water purity with the HM Digital TDS-4 water tester meter. The reading came back 174 (high is bad, low is good).

I checked the water on the old filter, which came with the fridge, which had been used for about 6 months. That water (which I was also drinking out of), came back at a reading of 145.

My tap water for reference is 183.

Not sure if other people have run these tests on this specific product on Amazon. Not sure if I should be finding this in a store somewhere instead, or buying directly from their website.
