A complete well water filtration system cost $2,231.25 to $4,422 in equipment at our Sep 12, 2026 price readings: $2,231.25 for a standalone air-injection iron filter, $3,123.75 for an iron filter plus water softener package, and $4,422 for the full stack with UV disinfection. Professional installation adds $300 to $1,500 per softener-class unit per Angi, HomeGuide and Fixr 2026 guides, and a well stack is usually a multi-tank job.
That makes private wells the most expensive corner of home water treatment, and the one where quotes deserve the most scrutiny. Here is what each dollar actually buys, one stage at a time. The diagnosis that comes before the budget, which contaminant you actually have, lives in our well water treatment guide.
The short answer
as of Aug 28, 2026How much does a well water filtration system cost?
$2,231.25 to $4,422 in equipment at our Sep 12, 2026 readings, depending on how many problems your water test finds: $2,231.25 for a standalone air-injection iron filter, $3,123.75 for iron plus a salt-based softener, and $4,422 for the full stack with UV disinfection.
Installation runs $300 to $1,500 per softener-class unit, and a well stack is two or three units plus a brine tank, so budget $600 to $3,000 for the labor. Over ten years, an iron-filter-only setup stays near $2,500 installed because it consumes nothing, while the fully loaded stack with salt, UV bulbs and multi-tank labor lands roughly between $6,600 and $10,000, our arithmetic on the figures below.
Key takeaways
- Equipment is $2,231.25 to $4,422 depending on how many of iron, hardness and bacteria your test actually finds.
- The stage order is fixed: iron and sulfur first, softener second, UV last. Reversing it destroys resin.
- Consumables are cheap on a well and the equipment is expensive, which is the opposite of city-water filter economics.
- The SpringWell WS1 is rated 7 ppm iron, 1 ppm manganese and 8 ppm sulfur; past those numbers the whole budget changes.
- A state-certified lab test is the cheapest line in the budget and the only one that stops you buying tanks you do not need.

Why Is Well Water the Most Expensive Water to Treat?#
Because you are buying two or three systems, not one. City water shows up chlorinated, iron-free and regulated, so a single whole house filter usually covers it. A private well can serve up iron stains, rotten-egg sulfur smell, manganese, hardness and microbiological risk all at once, and no single tank treats all five.
The stack, in the order the water meets it
Sediment, if the well carries grit
A cheap cartridge ahead of expensive tanks. Sand and rust flakes chew pump seals and blind the media downstream.Air-injection oxidation, for iron, sulfur and manganese
The biggest line on the bill and the stage that protects everything after it. This is what turns dissolved iron into something a filter bed can catch.Ion-exchange softener, for hardness
Second, never first, with its resin now protected from iron fouling. Sizing follows the same grains-per-gallon arithmetic as any city install.UV purifier, for bacteria
Last, on water already clear enough for the light to reach through. It is the only stage with a recurring part, an annual bulb.
You can skip stages your water test says you do not need. You cannot reorder them without paying for it in resin and media life.
What Does Each Stage Cost?#
$2,231.25 for the iron and sulfur tank, roughly $892 more to add the softener as a package, and about $1,100 for a UV unit. Priced separately the stages add up faster than the combos, which is the one place the well market rewards buying a bundle.
What each stage is for
- SedimentA cheap cartridge ahead of expensive tanks. Well water carries grit that chews pump seals and blinds the media downstream.
- Iron + sulfurThe air-injection tank, and the biggest line on the bill. The SpringWell WS1 is rated 7 ppm iron, 1 ppm manganese and 8 ppm sulfur; above those numbers the stack needs a stronger AIO or Katalox Light setup.
- SoftenerIon exchange, and it goes after the iron filter, never before it. Iron reaching untreated resin is how a $1,600 softener dies young.
- UVreplace: one bulb a yearThe only stage with a recurring part. Everything upstream of it has to be clear, because UV cannot reach through iron or turbidity.

The SpringWell WS1 at $2,231.25 (as of Sep 12, 2026) is the reference chemical-free iron filter: one tank, no consumables, media rated 10+ years. Two honesty notes. First, the product page shows a $5,100 strikethrough that is a bundle comparison, not a real discount, so ignore it. Second, its ratings are 7 ppm iron, 1 ppm manganese and 8 ppm sulfur; a heavily loaded well above those numbers needs a stronger AIO or Katalox Light setup, which SpringWell does not sell. The alternatives at that point are ranked in our best iron filter for well water guide.
For the softener stage, the US Water Systems Matrixx ran $1,295.95 (as of Sep 28, 2026, during a sale) and is the open-valve, rebuildable option plumbers tend to respect; our best water softener for well water ranking covers the alternatives, and the SpringWell softener review covers the other half of the combo below. Size that stage on your own numbers before you buy anything: the sizing guide shows why iron inflates the effective hardness a softener has to handle.
SpringWell
SpringWell WSSS1 Well Water Filter + Salt Softener Combo

- Iron rating
- 7 ppm
- Sulfur (H2S) rating
- 8 ppm

- AIO iron filter first, then softener (protects the resin)
The WSSS1 combo at $3,123.75 ($3,123.75 to $3,570 depending on size, as of Sep 12, 2026) pairs the WS iron filter with the SS salt softener in the correct treatment order. Adding UV on top brings the packaged ULTRA system to $4,422 at the same reading. A standalone SpringWell UV unit listed at $1,036 on the shop page that day, though SpringWell showed different UV prices on different pages the same day, so verify the live number before you budget it. UV also carries the stack's one recurring part: an annual bulb replacement around $130 per SpringWell's replacements category.
How Much Does Installation Add?#
$600 to $3,000, our framing on the published per-unit range, because a well stack is two or three tanks rather than one. The published 2026 figure for installing a softener-class unit is $300 to $1,500 (Angi, HomeGuide, Fixr, plus SpringWell's own FAQ), and a stack multiplies it.
Each tank needs its own connections, the softener and the backwashing iron filter each need a drain line, the brine tank needs floor space, and the UV system needs an outlet. There is no honest single national number for the whole job, so get the quote itemized per stage and sanity-check each line against that $300 to $1,500 unit range. That is the same discipline we apply to dealer quotes in the quote decoder, where an iron filtration add-on is priced at $1,000 to $2,500 inside a package.
What Does a Well System Cost Over 10 Years?#
Roughly $6,600 to $10,000 for a fully loaded stack, and near $2,500 installed for an iron filter on its own. The spread is almost entirely equipment and labor, because a well stack consumes very little once it is running.

Our arithmetic from dated readings and attributed 2026 ranges. The string rows are not summed; adding them puts this fully loaded stack roughly between $6,600 and $10,000 over 10 years.
The structural point: consumables are cheap on a well stack, and the equipment is what you pay for. That is the opposite of the cartridge-filter economics that dominate city-water systems, and it is why a well budget should be judged on the purchase rather than the yearly line. Compare it against a city-water softener budget in our water softener cost breakdown.
When Does the Budget Go Higher?#
When the lab report finds something these ranges do not cover. Three results push the price past this page: iron above 7 ppm, heavy hydrogen sulfide, and bacterial contamination.
Iron above 7 ppm calls for a stronger AIO or Katalox Light media; heavy sulfur calls for peroxide injection; bacteria makes UV mandatory rather than optional. None of those have honest fixed prices without a water test in hand, which is why any dealer quoting a five-figure number before seeing your lab results is quoting their margin, not your water.
Before you buy a single tank
7 itemsOnce the test tells you which problem you actually have, pick the hardware from the iron filter rankings and the softener picks built for wells. Whatever you install, the salt-side upkeep is the same as any city system: our maintenance checklist covers it.
What to Budget, by Problem#
$2,231.25 if your well only has an iron and sulfur problem, $3,124 for iron plus hardness, and $4,422 for the full stack with UV, at Sep 12, 2026 readings, plus $600 to $3,000 of labor. Over ten years, an iron-filter-only setup stays near $2,500 installed because it consumes nothing, while the fully loaded stack lands roughly between $6,600 and $10,000 by our arithmetic.
Get the state-certified water test first. It is the cheapest line in the whole budget and the only one that stops you from buying tanks you do not need.
Frequently asked questions
How much does a well water filtration system cost installed?
Equipment for a full private-well stack ran $2,231.25 to $4,422 at our Sep 12, 2026 readings, from a standalone iron filter to an iron + softener + UV package. Installation adds $300 to $1,500 per softener-class unit in Angi, HomeGuide and Fixr 2026 guides, and a multi-tank well stack is a bigger job than a single softener, so plan the upper half of that range or more.
Why does well water treatment cost more than city water treatment?
City water arrives disinfected and iron-free, so one filter usually does the job. Well water can carry iron, manganese, hydrogen sulfide, hardness and bacteria at the same time, and each problem needs its own stage: an air-injection iron filter, an ion-exchange softener, and a UV purifier. You are buying two to three systems, not one.
What order should well water equipment be installed in?
Iron and sulfur filtration comes first, then the softener, then UV last. The iron filter protects the softener resin from fouling, and UV works best on water that is already clear. Packaged combos like the SpringWell WSSS1 ship in this order by design.
Do I need a water test before buying a well system?
Yes, and sellers increasingly enforce it: SpringWell's own shipping policy, read Aug 30, 2026, holds well-water orders until a recent water test confirms the system matches the water. Private wells are not covered by EPA rules or city water reports, so a state-certified lab test is the only real picture of your iron, manganese, sulfur and hardness numbers.
