What actually fixes it

pick by what’s flagged above

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.

Complete system

Softener and carbon for every tap, plus Reverse Osmosis (RO) at the kitchen for what whole-home can’t catch.

$99 · normally $199

Next, start with your water heater

Hard water leaves sediment in a tank water heater and scale in a tankless. A $99 flush clears it, plumbing safety check included. Tankless descaling $300, regularly $350.
