Why Invest in a Whole House Water Filter?
Colorado tap water can contain chlorine, chloramines, sediment, heavy metals, and other contaminants. A whole-house filter treats water at the point of entry, so every faucet, shower, and appliance receives clean, filtered water.
- Healthier drinking, cooking, and bathing water
- Protect appliances from sediment and mineral buildup
- Better-tasting water from every tap
- Reduce skin irritation from chlorine
- Extend the life of water heaters and plumbing
- One system treats the entire home

How much does a whole house water filter cost in Colorado?
A professionally installed whole-house water filter typically ranges from $1,800 to $3,500 depending on the system, your water conditions, and whether a softener is added. Pure Water Choices provides a free in-home water test and upfront quote with no hidden fees.
What does a whole house water filter remove?
A whole-house carbon filter removes chlorine, chloramines, sediment, VOCs, herbicides, and other organic contaminants from every tap in your home. For additional concerns like heavy metals or PFAS, we design a multi-stage system tailored to your water.
How long does installation take?
Most whole-house water filter installations are completed in a single day — typically 2–4 hours. Our licensed technicians work cleanly and test the system thoroughly before leaving.
Do I need a whole house filter if I already have a water softener?
Yes — a water softener only removes hardness minerals, not chlorine, sediment, or other contaminants. Many Colorado homeowners pair a whole-house carbon filter with a softener for complete water treatment.
How often do filters need to be replaced?
Most whole-house filter media lasts 3–5 years depending on water quality and usage. We monitor your system and notify you when service is due.
