Filter Aid is diatomaceous earth pulverized to a white white powder. Filter acts as an attractant to the mineral particles in maple syrup. The Filter Aid sticks to the minerals and increases their size. The increase in size is what allows the filter papers to catch all particles in maple syrup. Filter Aid should only be used with Filter Presses.
We sell Food Grade Filter Aid ONLY. You are advised NOT to use swimming pool grade for maple syrup even though it is much less expensive.
