Residential Water Purification in Colorado

A purification system removes contaminants from your home's water supply, improves taste and odor, protects your family's health, and can save you money over time compared with bottled water.

Consider your water quality, budget, system size, maintenance requirements, and energy consumption. A water quality test is the best starting point — and our water treatment specialists help you match the technology to what's actually in your water.

Some systems can be installed yourself, but we generally recommend professional installation. Proper installation makes sure the system works safely and at full effectiveness — and we stand behind our work.

In general, filters should be replaced at least once a year. Carbon filters typically last 6–12 months, UV lamps need annual replacement, and RO membranes last 2–5 years. We keep the replacement schedule on file and remind you when service is due.

A drop in water pressure, or a strange taste or odor returning to your water, are the usual signs it's time for service. A TDS meter can also verify that a reverse osmosis system is still performing — if the reading creeps up, the membrane may need replacing.

Purification removes contaminants that affect health and taste — chlorine, lead, nitrates, pesticides. Softening removes hardness minerals (calcium and magnesium) that cause scale and soap scum. Many homes need both — a softener for the whole house and a purification system for drinking water.

Colorado's municipal water is treated and disinfected before it reaches your home, but the treatment process itself adds chlorine and creates disinfection byproducts. The CDPHE monitors these under the state's surface water treatment rules — but the byproducts still flow to your tap, and older homes can add lead from plumbing along the way. A purification system gives you a final barrier.

It depends on the technology — a point-of-use carbon filter starts around $300–$600 installed, while a reverse osmosis system runs $800–$1,800. Whole-house purification systems cost more because they treat every tap. The only honest answer comes after a water test — we'll explain exactly what you're paying for and why.

Point-of-use (POU) systems treat water at a single tap — usually the kitchen — and are the most common residential setup. Whole-house (point-of-entry, or POE) systems install at the main line and treat every tap, shower, and appliance. POU is more affordable and targeted; POE is more thorough but costs more and requires more maintenance.

When chlorine disinfects water, it reacts with organic matter to form byproducts like trihalomethanes (TTHMs) and haloacetic acids (HAA5). The EPA regulates TTHMs at 0.080 mg/L and HAA5 at 0.060 mg/L because long-term exposure is linked to cancer risk. These compounds form in the distribution main overnight — your water utility may be in compliance, but the levels at your tap can vary. A carbon filter or RO system reduces them.
