How should I store my Phoenix Gravity New Millennium Edition™ filter elements and how long do they last?

In theory, Phoenix Gravity New Millennium Edition™ filter elements have an unlimited shelf life. If you have already used your filter elements, the following applies: for long-term storage, we recommend that you dry the filter elements completely first. Make sure they are bone dry (no more moisture) before storing them for an extended period. Shake excess water off the elements and then let them air dry by placing them on a windowsill or other sunny spot for 3-4 days until they are completely dry. Once the elements are bone dry (no more moisture), store them in a sealable plastic bag (of at least 4 litres) - this will prevent the filter elements from absorbing odours. When you want to reuse your filter elements, clean them by scrubbing the outside with a hard brush or a (Scotch-Brite) scouring pad under cold running water. Then prime the filter elements again before replacing them in your water filter.
