This is the order you place so you never have to place it again soon. Sixteen sealed carbon cartridges and sixteen pre-filter sponges work out to roughly eight months of two-week changes for one fountain — or a full season for a two-fountain, multi-pet household — and the per-filter price lands well under every smaller pack.
Veken also drops four cleaning brushes into the box, which is a small thing that changes behaviour: when the brush is sitting next to the spare filters, the pump actually gets cleaned on schedule, and a clean pump is the single biggest factor in how long a fountain stays quiet.
