These filters are great! I just installed my second one. There was nothing wrong with the first one, bit the plumbing has to be replaced after 5 years. Mine was pushing 6 years and I didn't want to risk broken lines. Installing it is really easy and takes about an hour depending on space and if you have basic plumbing skills. Filter replacement takes 5 minutes.

After more than twenty years of having 5 gallon bottles of spring water delivered, the water started to have a strange taste/odor, so I canceled my delivery service and started looking for alternatives and the New York Times Wirecutter review recommended this one for removal of chlorine, plastics, and metals at a low price. Installation was straightforward (although I wish the lettered parts were included in the numbered diagram) and immediately after the recommended 10 minute flush out period my tap water, which is not horrible but has a chlorine taste, tasted great. I plan to fill a 3 gallon glass water cooler bottle with this filtered water to use with my existing cooler so I always have cold and hot water available as usual. My yearly cost for drinking water will be reduced by about 70% once I factor in the cost of replacing the filters every six months. Highly recommend!

Excellent tasting filter. Easy to install. Wish the water flow was a little better but overall I am very happy to have it.

Fits good, works good, good price. Comes with battery, which was convenient and unexpected.

AO Smith Under Sink Water Filter... https://www.amazon.com/dp/B07NJ4P99G?ref=ppx_pop_mob_ap_share AO Smith filter was purchased after I read many positive reviews. I've been using it for about a month and so far it has been great with no leaks. I am looking forward to the savings I'll have because of the life and cost of these filters. Used with items below --> Straight Stop Valve, SUNGATOR... https://www.amazon.com/dp/B0CLY7K4LK?ref=ppx_pop_mob_ap_share Valve works great! 1 day after I received it I had a leak at a old tap made in my copper pipe mostly because I touched it after I added my water filter and I believe the seals inside were very old. So I cut the horrible mess of plumbing and added this valve inline and am happy to say no leaks and hopefully my copper pipes will be better with this setup and have a long leak free future. John Guest Speedfit 1/4 Inch... https://www.amazon.com/dp/B005S4NYI8?ref=ppx_pop_mob_ap_share JOHN GUEST 1/4" One Way Check... https://www.amazon.com/dp/B00AELC3MI?ref=ppx_pop_mob_ap_share John Guest fittings have a lot of positive reviews and customers said they are good quality. So far I have no reason to say they are not quality. Every John Guest fittings I have used so far has been leak free and just works. I do recommend these fittings over other questionable brands. John Guest 1/4 Inch x 25 Feet... https://www.amazon.com/dp/B00N4O434I?ref=ppx_pop_mob_ap_share The John Guest brand has a lot of positive reviews and customers said they are good quality. So far I have no reason to say they are not quality. This tubing looks nice and appears to be of quality material and works well for my needs for my refrigerator supply line. SUNGATOR End Cap, 1/2-Inch Push... https://www.amazon.com/dp/B082KXR42G?ref=ppx_pop_mob_ap_share I have confidence with these caps from my experience with the Sungator Straight Stop Valve. I purchased these in case of a emergency and if I need to temporarily cap a line before I can do a repair.
