AO Smith Under Sink Water Filter System - Reduces PFAS, Lead, & Chlorine in Drinking Water - Under Counter Claryum Filtration for Kitchen - 2-Stage - AO-US-200

Ordered this after our 3rd Brita canister cracked. Install was easy enough that a bacon salesman (me) could be the install tech. Small, compact, and very solidly built system that now gives us great filtered water without the hassle of cracked canisters and refilling every day or so. Turn the tap and drink the water. The filters are easy to access and replace. Love it!

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!

Product works just as expected. Flow rate is good. Installation was fairly simple other than reaching behind the sink to install the filter faucet. I experienced no leaks but I did use plumbers tape on all the connections. HIGHLY RECOMMEND! Makes my water taste so much better but I have to say its not Poland Spring.

This was easy to hook up but runs extremely slow. It claims it runs at about 0.5 gallon per minute, but I'm timing this at 3.5min to fill half a gallon. UPDATE-I temporarily bypassed the filters and found that the faucet flow increased significantly. I contacted the company, but they said they could only help with issues related to the equipment itself, not the filters. I explained that the unit ran slow from day one and was less than two months old. I was told the main office would call me back, but I never received a call. I threw this unit away and purchased a two stage Waterdrop filter system. The new system fills my water bottle in just 37 seconds, compared to the 3.5 minutes it took with the AO Smith unit.

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.

I purchased these in case of a emergency and if I need to temporarily cap a line before I can do a repair.

Installed and the water tastes great. I threw away the battery pack that comes with it you do not need that. Not sure why it needs to be there. It's useless

I have just finished installing my unit this morning and cannot yet attest to its longevity, but I can say it looks nice and was relatively simple to install. IMPORTANTLY for anyone considering this product but concerned about reviews mentioning leaks upon installation, I want to suggest everyone to spend a few more dollars on some plumber’s thread tape. This is a thin plastic, not truly a tape as it has no adhesive, but will attach to itself. You wrap it around the threading 2-3 times at each connection point and this should prevent any leaks. When I first installed the unit, I had leaks from the brass t-connector as well as the connection from the white pipe to the faucet, but once I added this tape there were no more leaks. Save yourself a headache and just get the plumbers tape and use it from the start. I bought this tape years ago to replace my shower valves and it has proven useful numerous times. Bought mine from Home Depot. Another note: my product came with only one white tube, though the instructions listed two. Mine was long enough to simply cut in half to use for both ends of the filter. Just be sure to use a sharp knife, scissors or snips to cut and avoid over-crimping the tube. I used the cut ends for inserting into the filter and it works just fine.

Great product. Couldn’t find just the cartridges only the whole kit
