What actually fixes it

your free test confirms the right fit

Carbon / pitcher filter

Cuts chlorine taste & some byproducts. A good first step — misses nitrate, chromium-6 & PFAS.

Reverse Osmosis (RO)

Under-sink drinking-water system — removes the widest range: byproducts, nitrate, chromium-6 & PFAS.

Whole-home + RO

Softener / carbon for every tap, plus RO at the kitchen for what whole-home can’t catch.
