Product review (4 stars): Works Great. Hate the price. Beware low grade filters! This is NSF-53 certified.
There is nothing wrong with this filter. I flushed it four gallons as stated on the instructions. That's a lot but, ok, I'll do it. Water tastes fine with no odor. Note that this filter is rated NSF-53 for contaminants including lead. The cheaper filters are only NSF-42 which is just taste and odor. Don't be fooled. Those filters are not the same. You can't be sure those filters are removing lead and pcbs from your water. I just hate that it's $20 more than the previous filter from PUR which was also rated NSF-53. It can't be that much more to produce so this is just greed.
