3M Aqua-Pure Under Sink Reverse Osmosis Replacement Membrane Cartridge AP5500RM, for use with AP-RO5500 System

Works rerally good and easy to install

Works good for us... but what a pain to replace. The directions should be written by someone who has had to get their old body inside and up-under the kitchen sink and had to actually find the correct connections to take off. After hours of moaning, groaning and swearing trying to take the white connectors off just to find out you need to be working on the gray ones (with the same success)... then all of a sudden one just pops off... how did I do that...? Another half hour and shazam another one slips right off. You finally find the nack (and the right round nosed needle nose) that makes the job just a pain instead of a nightmare.I'm glad it's over and hope I slip away (die) after a Thanksgiving Dinner (and after dessert) with all my family ... before this thing ever needs changing again!Until then the water tastes great... clean and clear! ...100% happy with the way it works.

Direct replacement. I had to unscrew 3 ends, and use my original ones due to design change. Still took me less than 10 minutes, and our water flow was back to full stream. Marked the date on all filters, and will change every 2-3 years moving forward. Great deal!!

This is the 3rd one I ordered and all 3 have been cracked and leaked everywhere. And now I missed the return window on this one by 1 lousy day so now I have wasted way too much money on this terrible product. I want my money back.

Exact match for original OEM filters. Easy install. Be sure to mark the date you installed on each filter. I usually base changing filters on output of water. I'll be purchasing them again next timel

expensive

this filter has worked well for us over the years. Generally lasts about two years. I do have a plumber install it, however.

The filter is leaking with in 6 months, Is there any warranty on this?
