We got this 2 weeks ago, it was easy to install, you can see as the filter gets used up, my water now has a better taste, and actually you can physically see a cleaner water. Removes over 70 different contaminants, including 99 percent of lead, 96 percent of mercury , and alot of pesticides,  all of this combined gives me a sense of relief knowing all my grandchildren drink our water, works up to 3 months without filter change
