TDS & WATER QUALITY: Heads up — TDS meters aren’t the be-all and end-all of water quality. Why? ‘Cause essential minerals like calcium, potassium, sodium, and magnesium are dissolved solids too. That means your TDS reading might not budge, and that’s actually a good thing! Our Waterdrop under-sink system keeps these beneficial minerals in your water while filtering out the nasty stuff you don’t want. Quick note: Our activated carbon is made from natural coconut shells. So if coconuts aren’t your thing, double-check before you get filtering!
