Nobana Replacement A8 RO

Replacement RO membrane cartridge for the NOBANA A8 600/800 GPD tankless system. This is the second of the two cartridges — the actual reverse osmosis membrane that removes 95%+ of dissolved solids and gives the A8 its drinking-water quality.

Why we sell it — when the A8 starts dispensing water that tastes harder than usual or your TDS meter shows the output climbing, the RO membrane is the part to swap. We hold A8 RO membranes at Sannat. If you're not sure when yours was last changed, drop in with your unit and we'll TDS-test it for free.
