Geekpure 5-Stage RO Replacement Filter Set — Complete Kit with 75 GPD Membrane, NSF Certified! $59.83 CAD (25% Off)

💧 Geekpure 5-Stage RO Replacement Filter Set — Complete with 75 GPD Membrane, NSF Certified

If you've got an under-sink reverse osmosis system, you know the annoying part isn't installation — it's finding replacement filters that actually fit. Geekpure's 5-filter set uses the industry-standard 10-inch size (2.5" OD x 10" prefilters, 1.8" x 12" membrane), so it swaps straight into most mainstream RO systems from iSpring, Watts, Premier, APEC, Crystal Quest and more.

The box includes all five stages: PP sediment filter, granular activated carbon, carbon block, a 75 GPD reverse osmosis membrane, and a post inline coconut carbon filter. The membrane rejects up to 99% of contaminants including arsenic, lead, fluoride and heavy metals, and the set is NSF-certified from an ISO9001 manufacturer and WQA member.

Right now it's $59.83 CAD, down from $79.99 — you save $20. With typical use, the prefilters last 6-12 months and the membrane 15-24 months, so this kit covers a year and a half or more. Each filter is individually sealed for longer shelf life, and two 1/4" quick fittings plus a roll of Teflon tape are included — a DIY swap takes about half an hour.

Just double-check your current filters are the standard 10-inch size before ordering. Replacement filters rarely go on sale, so 25% off is a good time to stock up.
