Whole Home Water Filtration System
Professional whole-house water filtration customized for Colorado water. Remove chlorine, sediment, VOCs, and contaminants from every tap in your home.
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

Point-of-entry filtration treats water before it reaches fixtures. It can be appropriate when the same concern affects several taps, but the media must match the target substance. Start with your current utility report or laboratory results rather than selecting a filter solely because the water tastes different. Compare the exact model’s certified reduction claims, rated flow, and replacement requirements.
What this treatment does not replace
A sediment cartridge is not a substitute for a dissolved-contaminant filter. Carbon products also differ: a general taste-and-odor claim is not proof of chloramine, lead, or PFAS reduction. Removing a disinfectant from whole-home water changes how that water is protected inside plumbing. Maintenance and stagnation deserve attention, and filtration must not be treated as permission to ignore a boil-water advisory.
Prepare for an equipment assessment
Before discussing installation, locate the main shutoff and note pipe size, pressure problems, household occupancy, and simultaneous shower or appliance use. Take photos of the proposed equipment space and any existing bypass, softener, or filter. Ask which taps will be treated, whether a drain or electrical outlet is required, how service access will be maintained, and how performance will be checked after installation.
Compare scope and ongoing costs
A useful quotation separates equipment, plumbing modifications, consumables, and ongoing service. Higher flow requirements, unusual pipe access, pretreatment, or a combination system can change scope. Ask for model numbers and a written maintenance schedule before comparing quotes; no single advertised price describes every home.
Start with our overview of water treatment services. For more background, read chloramines and filter selection. When the primary problem is hardness scale rather than the substance a filter is rated to reduce, compare water softening.

Frequently Asked Questions
What determines the cost of a whole-house water filter?
Equipment, target contaminants, household flow, installation access, and ongoing media or cartridge replacement all affect cost. Request a site-specific written quote rather than relying on a general price range.
Will a whole-house filter remove chlorine or chloramines from Denver Metro water?
It depends on the filter and your water supply. Check your utility’s current water-quality report to identify the disinfectant, then match the specific model’s certified reduction claims to it. A chlorine taste-and-odor claim does not automatically establish chloramine reduction.
Is a filter the same as a water softener?
No. Conventional softeners target calcium and magnesium hardness. A filter targets the particles or substances its media is designed to reduce. One system does not automatically replace the other.
How often should filter media be replaced?
Follow the exact manufacturer’s instructions and account for water quality and usage. There is no universal service interval for all cartridges or media beds.
Can a filter make water safe during a boil-water advisory?
Do not assume it can. Follow the issuing utility or health department’s instructions, including any directions for flushing and replacing filters after the advisory.
