Bests & Worsts Reviews from Amazon

I expected so much that this pitcher would replace bottled water. I measured TDS values of three different water, bottled water 1 gallon sized from Costco, tap water before filtering, and tap water after filtering with this pitcher. The value is 29, 681, and 611. The filtering effect is negligible and I'm so disappointed with the results, because the TDS value of drinkable water is 0 to 50. I've gotta return it.
