3M Aqua-Pure Under Sink Full Flow Replacement Cartridge AP Easy C-CS-FF, for use in AP Easy CS-FF System

Received before projected date. Easy to install.

I got this to to decrease unwanted flavors (mostly chlorine) in my tap water. This filter does it nicely. The water tastes great.I can confirm that this fits the same filter holder as Aquapure's C-CYST-FF. I've used both filters. Both work well. Both give OK flow rate, though the flow through the C-CS-FF is distinctly faster. I would use the C-CYST-FF if I wanted filtration tight enough to remove microbes. For my water this isn't too much of a concern, so I choose the higher flow rate I get with the C-CS-FF. It's nice to have a choice!The filter holder for both allows you to change the filter without shutting off the water. Just thread the old one out, about a quarter turn, and thread the new one in. Only a few drops of water dribble down, so a dish towel under the assembly is all you need. Nice touch.========Below contains Update as of 2016-11-05:I have used these to remove chlorine and other species that contribute "taste" to my city water. They have worked well, and significantly improve the water flavor, but now seem to becoming less available and at significantly increased prices compared to a year or more ago.I've replaced it the whole thing with a permanant filter holder (many options available, check something like HD4500BL34) that houses disposable "carbon block" media, in industry-standard size of nominal 10 inch length x 2.5 inch diameter.Compared to the Aquapure kit, you'll have to source your own plumbing adapters and holder. But it's well within the capability of the medium-handy homeowner. I'm really liking the expanded range of options for filter media now.

I recently replaced my under sink water filter with the 3M Aqua-Pure Full Flow Replacement, and I couldn't be happier with the results! This filter delivers reliable filtration, ensuring that my family has access to clean and great-tasting water every time.

This filter works and very easy to install. I have tried other lower cost filters and got less than 1/2 the life of this filter.I’ve used this filter for 6 years and have no problems. Only thing is that it cost more then the off brands. I’ll pay the extra $$$ for something I know works.

I use this in my RV. It is easy to install and remove, and seems to do it's job well. It's too bad they are so expensive though.

Bought for Winnebago. I’m in a place with a private well ( normal for Florida-lots of water here). Water is yellow with sulfur taste. The water filter allows me to drink the water out of the tap without qualms!

Very easy to change without even having to shut off water (though I did) due to base's integral check valve, in my setup anyway. Removes taste of chlorine very well which otherwise ruins the taste of coffee for me. Previous cartridge lasted 3 years only small utility sink I use mostly for coffee, drinking, icemaker and cooking water, not for washing, etc. Tap water here in Bend, Oregon is superb anyway, winning the 2012 "Best Tasting Municipal Water In Northwest" and in running for best in USA, to be determined. I just hate the taste of chlorine.

This is perfect for our 2015 Itasca Winnebago Ellipse Ultra water filter! Easy to install, thank you AMAZON.
