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

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!

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.

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

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 need these 2-step filters for the drinking fountain attached to my kitchen sink. These for my system perfectly as expected and are easy enough to install (the hardest part is that the area under my sink is hard to reach). They seem to last a long time (4-6 months), just as long as my refrigerator water filter. They seem to do the job well and the water tastes good, after the initial rinse through. This 2 pack is the best value I've been able to find.

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.

The system it self is excellent and changing it when necessary is simple enough...... there is a tray which holds a lithium battery and I accidentally broke it.... I inquired through chat and asked if the replacement for the filter came with a tray...I was told yes, but it wasn't included... I called the company and was told the battery holder isn't for sale as an accessory, and it wasn't necessary for the filter to work..... I took his advice and the system works really well... tray or not. Just don't break the tray:-)
