To make your filter last as long as possible, at maximum efficiency, we advise that your filter is soaked once a month. These handy canisters are slim and easy to store and come with a lid which will keep the filter from floating up so that the whole filter is submerged in the solution.
Monthly:
Rinse filter with a hose pipe.
Soak overnight in dissolved Filter White, in the canister.
Rinse off thoroughly with a hose pipe the next day.
Leave to dry thoroughly (So that the paper fibres can fuse back together properly).
