Reverse Osmosis Drinking Water for St. Louis Homes

The cleanest drinking water you can get at the tap. Tankless under-sink RO with its own dedicated faucet, included in the whole-home bundle or available as a stand-alone add-on.

Why RO matters in St. Louis

Your softener does not handle everything at the tap.

Whole-home softening and carbon filtration treat the water reaching your fixtures. Reverse osmosis adds a second line of defense specifically at your drinking water source, targeting contaminants that slip past other treatment stages.

Chloramine removal

Missouri American Water uses chloramines for disinfection. Carbon filtration reduces them at the whole-home level; RO removes what remains at the tap, producing drinking water with no chemical taste or odor.

Heavy metals and lead

Many St. Louis homes, especially those in older south city neighborhoods, have lead service lines or lead solder in interior plumbing. RO at the drinking tap is the most reliable at-home defense.

PFAS and dissolved solids

The RO membrane removes dissolved solids, PFAS compounds, nitrates, and other contaminants that pass through standard carbon and sediment filters.

Tankless design

No storage tank to harbor bacteria. Water is produced on demand, keeping the system compact under your sink and eliminating the maintenance headaches of traditional tank-based systems.

Dedicated faucet

A separate RO faucet goes right next to your existing kitchen tap. Fill glasses, cook, and make coffee from the same spot without switching anything.

Quality RO membrane

A high-performance membrane and pre-filters remove dissolved contaminants including chloramines, PFAS, and heavy metals. Installed by a local professional.

Included in the flagship bundle. Most customers add RO as part of the whole-home softening and filtration package. It is also available as a stand-alone add-on if you already have a softener in place.
