Geekpure 5-Stage RO Replacement Filter Set — Full Year of Filters + 75 GPD Membrane! $59.83 CAD (25% Off)

💧 Geekpure 5-Stage RO Replacement Filter Set — A Full Year of Filters, One Box

If you run a reverse osmosis system under your sink, the annual filter swap is a cost you can't skip. OEM cartridges run well over a hundred dollars a set, so plenty of people put it off — and then wonder why the water flows slower and tastes off.

This Geekpure set bundles all five stages in one box: the PP sediment filter (stage 1, catches sand and rust), granular activated carbon (stage 2, removes chlorine and odour), carbon block (stage 3, mops up residuals), a 75 GPD RO membrane (stage 4, filters out arsenic, lead, fluoride, and heavy metals), and a post coconut carbon filter (stage 5, polishes the final taste). You also get two 1/4" quick fittings and a roll of Teflon seal tape, so there's nothing left to buy separately.

The sizing is the standard 10" × 2.5" used by most under-sink RO systems — iSpring, Watts, Premier, APEC, and more. That matters, because the biggest worry with aftermarket filters is fit, and standard sizing removes it.

The manufacturer is WQA (Water Quality Association) member and ISO9001 certified, with the membrane rated to remove up to 99% of contaminants. Right now the set is $59.83, down from $79.99 — a 25% saving. If your RO system is due for its annual change, this one box covers the whole year without multiple orders.
