๐ง Geekpure 5-Stage RO Replacement Filter Set (5-Pack) โ One-Stop Swap with NSF-Certified Membrane
If you have an under-sink reverse osmosis system, you know filters need replacing on schedule โ and buying each stage separately is a hassle. This Geekpure 5-pack bundles everything: PP sediment, granular activated carbon, carbon block, a 50 GPD RO membrane, and a post coconut carbon filter. It's $56.98 CAD right now, down from $75.99 โ 25% off.

The filters are standard 10-inch size, so they fit most 5/6-stage under-sink RO systems without measuring. The RO membrane is NSF-certified and removes arsenic, lead, mercury, fluoride and dissolved solids. Each filter is individually sealed to stay fresh on the shelf.
Two things to know before swapping: flush the new membrane for 30 minutes first, and lifespan depends on usage and feed water quality โ the sediment and carbon stages last 6-12 months, the membrane 15-24 months. The kit also includes 2 quick-connect fittings and Teflon tape, so no extra parts needed for the post filter.
Geekpure has been making water filtration products for 20+ years and offers 24/7 tech support. If your RO system is due for new filters, this all-in-one set is easier and cheaper than buying individually.
