Filter Combo Packs & Replacement Cartridge Bundles
Buying your filters as a set is cheaper and simpler than tracking down each cartridge on its own schedule. These combo and bundle packages match the exact filter sets for popular RO systems, whole-house units and under-sink setups — Culligan, GE, Hydrotech, Aqua-Flo and universal 4-stage kits — so one order covers a full service interval.
How to choose a bundle
Buy by system. Kits are assembled for a specific unit (Culligan AC-30, GE GXWH04F, Hydrotech) — match your system and every cartridge is the right one.
Membrane in or out? Some RO kits include the membrane, some are pre/post filters only — check the listing so you don't double-buy.
Set your schedule. Most under-sink pre/post filters change every 6–12 months; the membrane lasts longer. A yearly bundle keeps it simple.
Universal fits, too. Don't see your brand? Universal 10" sediment/carbon kits fit standard housings across most systems.
Give us your system and we'll confirm the exact set — or build you one. Get matched.
