Geekpure 5-Stage RO Filter Set — 5 Filters + 75 GPD Membrane! $62.98 CAD (21% Off)

Amazon.ca has the Geekpure universal 5-stage RO replacement filter set (with 75 GPD membrane) for $62.98 CAD (list $79.99, 21% off). Prime members ship free; non-Prime orders over $35 CAD ship free.

If you have an under-sink reverse osmosis system, filters are a yearly consumable. This set covers all five stages at once: PP sediment, granular activated carbon, carbon block, a 75 GPD RO membrane, and a post inline coconut carbon filter. Two 1/4" quick fittings and a roll of Teflon tape come with it.

Everything is standard 10" sizing (the three pre-filters are 2.5" x 10", the membrane is 1.8" x 12", the post filter is 2" x 10"), and Geekpure says it fits standard-size systems from iSpring, Watts, Premier, Flowmatic, APEC and others. Measure your cartridges first — standard sizes work, non-standard won't.

The membrane is rated to remove up to 99% of contaminants including arsenic, lead, fluoride and heavy metals. The manufacturer is ISO9001-certified and a member of the Water Quality Association, and every filter is individually sealed.

Buying five filters separately usually runs $80-90, so $62.98 is a decent time to stock a set. It's currently #8 in Replacement Water Filters.
