This filter housing wrench is a perfect fit for most standard filter housings, including the H2 and H3 housings we sell on the Alkaline Water Plus website. It is used to tighten or loosen the housings when you need to change your filters. We suggest you store this tool right with your housings, so as to always have it handy when you need it.
- This is not an AOK filter housing wrench. If you need that filter wrench please contact us and we'll help you.
- The C3 and PureEasy systems do not have or require filter wrenches.
