Reverse Osmosis RO 800G & PCB Water Replacement Filters
New filters in torn clear wrapping - no box. Filters show some shelf storage wear. I do not know what system these are compatible with so please see the measurements in description and see the specifications in pics of canisters. The RO canister states 800g so I am assuming that means 800 gallons?
Approximately 15.5" long x 4.25" in diameter.
