Reverse Osmosis

Bottled-quality water,
straight from your tap.

CASA reverse osmosis systems filter your Utah water through 5–7 stages and remineralize it for great taste — pure drinking and cooking water on demand, no plastic bottles.

Why RO

Cleaner water, less waste

🔬

5–7 stage filtration

Removes chlorine, lead, PFAS, dissolved solids, and the stuff that makes water taste "off."

Remineralized

An alkaline stage restores healthy minerals after filtration, for balanced, great-tasting water.

Stop buying bottled

Endless clean water from your tap — no hauling, no plastic, no recurring cost.

Free Tool

Size your RO & whole-home system

Match capacity to how your household actually uses water.

The Math

See how fast it pays for itself

Most homeowners spend more on bottled water than a system costs to run.

Utah Water Sources & Quality

Where Utah’s water comes from — and how clean it is at the source

Every Utah source carries something different: dissolved solids, sediment, hardness, algae or salinity. Bigger circles are larger supplies; greener is cleaner at the source, redder needs more treatment. Reverse osmosis removes what the source brings with it.

Scores are CASA estimates of raw source-water quality, compiled from Utah water-provider data. Nearly every Utah source benefits from filtration; high-TDS and surface sources benefit most from reverse osmosis.
