Recommended for this suburb

TDS in West Island Cocos (Keeling) Islands is 858 mg/L — above the 600 mg/L guideline. That's a lot of dissolved mineral passing your lips.

TDS is the total of every salt, metal and mineral dissolved in your water. At this level, water tastes flat or mildly salty, kettles descale constantly, and skin/hair feels rougher after a shower. Standard carbon filters won't move this number — they're designed for taste and chlorine, not dissolved solids. This is the one water issue where you genuinely need RO; no other consumer filter gets close.

RCC7AK 6-Stage Under-Sink RO (with Alkaline Re-min)

4.6 · 13,756 ratings on Amazon

Reverse osmosis pushes water through a sub-micron membrane that blocks 90–99% of dissolved solids. The water that comes out the other side reads 50–100 mg/L — drinking-water-plant territory. Installs under the sink, with its own tap above the bench.
