The 5 Best Water Filter wrenches (2023 reviews)

It’s a simple metal wrench, and there is not much to say, except that it does the job perfectly. This wrench, although thinner than the plastic one, is much sturdier. The key here is that this product is metal with strength in the horizontal direction where you apply torque. The handle is rubberized and longer than a standard filter wrench which gives you extra leverage, along with the word "loosen" and an arrow imprinted to ensure proper removal of the housing unit.

In addition to being metal, the handle is also nearly twice as long as the handle on the plastic wrench, giving you more leverage. The metal wrench is a must.
