AO Smith Basic Direct Connect Under Sink Replacement Filter For AO-MF System - Carbon Block Filter Reduces Up To 99% Of 9 Harmful Contaminants - AO-MF-R

I've heard of others complaining about the filter not lasting 6 months but this depends upon usage and other events such as one we had where our water supply was contaminated due to flooding. I feel the filter did its job though as we experienced no change in taste, which is good. FYI - my primary purpose for use is to make my coffee taste better by eliminating the metalic chlorine taste in our water, which this does. Out of caution, we triggered the new delivery of a filter from Amazon since we have a subscription. I'm pleased to see it (claims) to remove microplastics too. The unit itself was installed by a local plumber we trust quite a while ago. Replacing the filter is very easy, just turn off the water and have a bucket nearby in case of some water dripping out. One note of caution is you MUST use this exact filter or what you get will not fit! It will seem close but will be a bit wonky and will leak quite a bit. We tried to grab one that looked the same from Lowes which carries AO-Smith but was different as it turns out. So, be sure you have the correct filter, the AO-MF-ADV. Honestly, it's not easy to find this badging on the shelves at Lowes. They often don't have this in stock. I find this a very nice system to use. If you have young kids, you may want to give them water out of another tap than the one this is installed on since this probably eliminates much/all of the fluoride in the water. Keep those kids' teeth healthy! Though Amazon and other still sell these filters, can anyone tell me if AO Smith still sells these or manufactures these still or are they moving to other systems? I absolutely cannot find these filters on AO Smith's site.

I have bought several of these. They work as advertised. Arrived packaged well, no issues.

Easy to install, leak-free. We love our AO Smith water filtration system!

The AO Smith filter system has really improved the taste of my water and I feel better knowing “stuff” I don’t need/want is being removed. Replacement filters super easy to swap out.

We love this filter,it is the only one we purchase. Price was good. No problems with at all.

These filters work great but they cost way too much. The filter gets 5 stars but the price gets 1 star.

I have been using this filter system for a couple of years now since discovering it when our water smelled and tasted like lake water. It is simple to install. I had to do a bit of modifying to add a dedicated faucet. It has been my go to as my routine water bottle refill. The water is tasty from it and I replace every 6 months.

We've been using this system for over a year and are happy with the results.
