AO Smith 2-Stage Under Sink Clean Water Faucet Filter - Carbon Block Drinking Water Filtration System - AO-US-200

Very good value for the money. We replaced our RO system with this, takes up very little space, easy to install, water tastes great and changing the cartridges is a breeze.

i think its wrong to have to through so much when the product has issues to get a replacement

Not a lot of space is needed to install under sink. Turns stinky Florida well water into the best tasting drinking water you have ever tasted.One hole through the granite countertop was necessary. All parts to install are included for a complete hookup.

Great product. I had to drill a .5" hole thru my stainless sink and that went well. It is an awkward reach from under the sink attaching the nuts and hose connector. A design like most of the newer faucets where the connection point hangs down about 12" would be much better. Unit is well built and opening the two canisters was easy and replacing them into the base is easy also. Water tastes great and flow rate is pretty good. I bought a set of replacement filters and they seem kind of pricey to me. Plan onlooking around and see if there are 3rd party that will work. Took about 2 hours to install and i'm pretty handy. I'm 67 and can see where it might be tough for an older person to install and you might want to hire it out.

We had previously purchased an under the sink water filtration system by aquatrue that was three times as expensive and about 75 times harder to install. We ended up returning that system because it leaked from every angle and purchased this system. let me tell you, it was super easy to install and the water tastes amazing. We had a little bit of leaking at the input for the faucet, but that was simply because we didn’t tighten it enough. Once we tighten it all the way (our faucet hole is in a very hard place to tighten) it was perfect. Instructions were clear and I love how little space it takes up since it does not have a reservoir tank.
