Reliable, lasts longer than advertised

This filter cartridge performs exactly as specified. Installed in my Texas home (where calcium-heavy water is a constant battle), it significantly reduces scale buildup and hardness, leaving water noticeably softer. The flow rate remains strong and consistent for about 7 months before needing replacement—no frustrating pressure drops at the sink. Taste and odor improvement is subtle but appreciated. Perfect for hard water woes; it’s saved my coffee machines from mineral havoc. Easy to install, durable, and worth every penny for its longevity and performance. A good contender if you’re looking for an under-sink water filter.

Good system for getting rid of metalic taste, plastic and other yucko stuff.

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.

Clogged up my Faucet!

I normally buy this filter from my local hardware store, but they stopped carrying it. So I bought it here on Amazon. After installing it and turning on the water, NOTHING comes out of the faucet! I turn off the water source under the sink and remove the new filter and get blasted by a massive deluge of water! I reinstalled my old filter and still no water out of the faucet. I put the new filter back on and tried again. No change. I also feed the water from this filter to my pot filler and refrigerator. The water flowed freely from the pot filler. While the water was coming out of the pot filler, I turned the sink back on and got a trickle of water. Over the next 10 minutes the sink finally achieved full functionality! The new filter had clogged the faucet with gunk!

Assures clean and safe water for cooking and drinking on village water system.

Two minute swap out and my water flows faster. Somewhat pricey filter cartridge but worth the confidence of having clean, clear water and no leaks.
