TL;DR: Reverse osmosis gives Utah County homes bottled-quality drinking water at the kitchen tap: $300–$1,500 installed for under-sink systems based on industry estimates, with filter changes yearly and membranes every 2–5 years. Call Utah Service Pros at 801-874-8479.
What does reverse osmosis remove?
RO forces water through a semipermeable membrane that rejects dissolved solids — typically reducing total dissolved solids (TDS) by 90%+ along with lead, nitrates, arsenic, and the mineral taste Utah County water carries. Sediment and carbon prefilters protect the membrane; a final carbon polish sharpens taste at the faucet.
Under-sink or whole-home RO?
Under-sink wins for nearly every home: you drink and cook with a few gallons a day, and treating only those gallons keeps cost and water use sensible. Whole-home RO exists for specific contaminant cases but wastes capacity on showers and irrigation — usually whole-home filtration plus under-sink RO is the right stack.
Does RO work with a water softener?
They are partners: the softener protects the RO membrane from hardness scaling and the RO strips the trace sodium softening adds — softened, RO-finished water is the standard premium setup here. Remineralization stages are available if you prefer mineral taste back. Start with water testing to see what your tap actually carries, or visit the softener page.
