Whole House Water Filtration in Denver, CO
Chlorine taste, sediment in the aerators, or simply unsure what is in the supply? Filtration only works when the media matches the contaminant, which is why testing comes before any recommendation rather than after.
Quick answer
What does whole house filtration actually remove in Denver?
Whole house filtration in Denver typically targets chlorine or chloramine taste, sediment from distribution work, and where present, lead picked up from older service lines. It does not soften water, because hardness is dissolved mineral that requires ion exchange rather than filtration.

What this work actually covers
Filtration and softening solve different problems and are frequently confused, which leads to households buying the wrong equipment. A filter removes particles and certain dissolved chemicals by passing water through media. A softener exchanges hardness minerals on a resin bed. Neither does the other one's job.
Denver Water supplies treated water that meets standards at the point it leaves the system. What arrives at a tap can still differ, because distribution mains disturb sediment, disinfectant residual carries a taste, and older service lines can contribute material of their own.
The right specification therefore begins with a test rather than a catalogue. A sediment problem needs different media than a chlorine taste, and a lead concern needs certified media rather than a general purpose cartridge.
Budgeting
What moves the price up or down
Media type and housing size
Sediment cartridges sit well below backwashing carbon systems in cost.
Flow rate required
Larger households need larger housings to avoid pressure loss.
Whether prefiltration is needed
High particulate loads need a sediment stage ahead of carbon.
Point of entry plumbing
Where the supply enters determines how much pipework the install requires.
Ongoing cartridge replacement
A real recurring cost that belongs in the comparison from the start.
Handling it yourself against calling us
| Factor | Doing it yourself | Calling us |
|---|---|---|
| Choosing equipment | Buying a filter and hoping | Water tested so the media matches the contaminant |
| Sizing | Rating on household size | Peak simultaneous demand and pressure drop calculated |
| Chloramine | Standard carbon that handles it poorly | Catalytic carbon where the test result calls for it |
| Hardness | Expecting a filter to soften water | Softening addressed separately, because it is ion exchange |
| Lead service lines | Treating a filter as the permanent answer | Filtration as interim while replacement is planned |
What a filtration installation covers
- Water testing to establish what is actually present
- Peak simultaneous demand calculated for correct sizing
- Media selected against the test result rather than a catalogue
- Housing and bypass fitted at the point of entry
- Pressure drop verified under real flow conditions
- Sediment prefilter fitted where particulate load warrants it
- Cartridge change intervals set from measured load
- Post installation testing confirming the result
The detail that matters
What actually goes wrong, and why here
Flow rate is the specification people most often get wrong, and the consequence is immediate. Every filter creates resistance, and a unit sized for a small household chokes the supply when two showers and a dishwasher run together. Sizing is done on peak simultaneous demand rather than average daily use, and the pressure drop rating matters more than the headline capacity.
Media selection follows the test result. Sediment filters are rated in microns and catch particulate, with pleated cartridges suiting moderate loads and larger backwashing units suiting heavy ones. Activated carbon addresses chlorine, taste, and odor, and where the utility uses chloramine rather than free chlorine a catalytic carbon is needed because standard carbon handles it poorly.
Lead deserves separate treatment because the answer is not really a filter. Where an older Denver property still has a lead service line, certified filtration reduces exposure at the tap while the real solution is replacing the line. Presenting a filter as a permanent answer to a lead service line would be misleading, and it is worth saying so plainly.
Unsure what is actually in your water?
Testing costs very little and it is the difference between buying the right equipment and buying equipment.

What you get
What changes after the visit
The media matches the actual problem
Testing first means paying for filtration that addresses what is present.
Sediment is caught before appliances
Whole house placement protects every fixture and appliance downstream.
Taste and odor improve at every tap
Carbon media addresses disinfectant residual throughout the house.
Flow rate is protected
Correct sizing avoids the pressure drop that undersized filters create.
Cartridge intervals are realistic
Change frequency is set from measured load rather than optimism.
Denver rules and local conditions that apply
Denver Water publishes annual water quality reporting, and that data is a sensible starting point before any property specific testing is done.
Where a property still has a lead service line, filtration certified for lead reduction is an interim measure. Line replacement is the actual remedy and should be planned rather than deferred indefinitely.
What happens after you call
Your water gets tested
What is actually present drives everything that follows.
Demand and pressure are calculated
Peak simultaneous use sets the housing size and acceptable pressure drop.
Media is selected against the result
Sediment, carbon, catalytic carbon, or certified media as the test indicates.
Installation at the point of entry
Housing, bypass, and any prefilter stage fitted where supply enters.
Flow tested and intervals set
Pressure under real load is verified and change intervals put in writing.
How long the work takes
A single stage whole house filter at an accessible point of entry generally installs in two to four hours. Multi stage systems with prefiltration and backwashing units run longer.
Water testing is done ahead of the installation so the specification is settled before anything is ordered, rather than fitting equipment and finding out afterward.
Warning signs
Signs the problem is already under way
A persistent chlorine or chemical taste
Disinfectant residual, which carbon media addresses effectively.
Grit in aerators or appliance screens
Sediment entering from distribution work or from corroding pipe.
Cloudy water that clears from the bottom
Fine particulate rather than the air bubbles that clear from the top.
Discoloration after a main is worked on
Disturbed sediment in the distribution system reaching the property.
A known or suspected lead service line
Certified filtration is the interim measure while replacement is planned.
Appliance screens blocking repeatedly
Particulate load high enough to warrant whole house sediment removal.

Common questions
Questions we field on this work
No. Hardness is dissolved mineral and needs ion exchange, which is what a softener does. They are different systems solving different problems.
It depends what your test shows. Denver supply meets standards, but taste, sediment, and older service lines all produce property specific issues.
Not if it is sized on peak simultaneous demand. Undersized filters are the usual cause of pressure complaints after installation.
It depends on measured load. Intervals are set from your actual conditions and put in writing rather than guessed.
Chloramine is a more stable disinfectant and standard carbon handles it poorly. Catalytic carbon is needed where it is present.
Certified media reduces it, but a lead service line should be replaced rather than filtered indefinitely.
For drinking water, often yes. Whole house filtration additionally protects appliances and every fixture from sediment.
Sometimes. They address different problems, and the test result shows whether both are justified.
Yes, and it happens before any recommendation so the equipment matches what is actually present.
Test first, then specify the filtration
Media matched to the result and sized so pressure holds.
