I have been very happy with these filters over the past few months. Flows faster than original OEM PUR filters, fits and works flawlessly. My only concern is that these filters don't actually have data to prove how well they filter, unlike pure OEM filters. I notice the difference in taste and am happy with it. Bottom line: I would only recommend these filters if your local tap water is already potable. I only use these filters as an extra precaution, they also improve the taste.
