(Advanced Filter System Replacement) - AO Smith Advanced Main Faucet Under Sink Replacement Filter for AO-MF-ADV System - NSF Certified - Claryum Filtration Reduces Up to 99% of 77 Harmful Contamin...

We are on a well and it's not the best water. Even though we have a whole house filter the water is still not great. This filter system took less than 10 minutes to install under our kitchen sink and our water quality improved significantly. The replacement filters are pricey but well worth the cost. We aren't getting the suggested six month life because of our water quality so we just change it when the flow volume is significantly reduced or taste deteriorates.

Love it. It is so easy to replace the water filter. We have well water and this filter gives us clean drinking water.

I want to have cold tap water with no clorene taste and filter out any other contaminants from the municipal water supply. Previously I used a different style filter where the filter sits in a screw on external housing. I got tired of fighting to unscrew that housing which seemed to get a little harder every time. This new style is more expensive to replace but far easier, just shut off the water supply to the filter, turn the housing and it releases. Put the new one in, turn until it snaps into place, turn the water back on and run for 5 minutes. That's it. It's good for 6 months. Highly recommend as an easy to use alternative.

We had this product attached to the cold water under our kitchen sink. It was really difficult to install, but my husband built a little wood platform for it and made it work. However, we recently moved and tried to buy another one for the new house. This filter is so big that we couldn't get it past our pipes to connect it anywhere under our sink. I suppose a proper plumber could make it work - but we had to send it back because of install difficulty.

We have been using these at our home, as well as our rental properties for several years. Even though we have well water, this bumps it up just enough to make the water excellent drinking. Changing it every six months is key. They are a little pricey, but well worth it. The alternative would be endless cases of bottled water, which we are not interested in.
