I use this wrench to remove three carbon/particulate filters on my APEC RO unit. It's amazing and works flawlessly. Very well built, very durable and lots of torque! This great tool is MUCH easier to use than the flimsy plastic devices that come with reverse osmosis kits. I would consider this a must have for any reverse osmosis system owner. BREAK! DON'T THINK ABOUT IT ANY MORE! GET IT NOW!
