Filtration and softening are two different jobs, and mixing them up is the most expensive mistake in this industry. A softener removes hardness minerals. A filter removes chlorine, chloramine, taste, odor and particulate. Most Eastern Iowa homes want both, which is why our standard build bundles them at $2,500 — but filtration alone starts at $1,150. Every price we charge is below.
| What it is | Price | What it does |
|---|---|---|
| Carbon-only filtration tank | $1,150 | Whole-home chlorine, taste and odor. No softening — your water still tests hard |
| Carbon-only tank, catalytic media | $1,450 | The same, with catalytic carbon for chloramine and better performance on sulfur and odor |
| Softener + whole-home filtration | $2,500 | Both jobs, one system |
| Softener + filtration + reverse osmosis | $2,850 | The above plus drinking water at the kitchen tap — our most common install |
| Catalytic carbon upgrade on a whole-home system | +$150 standard · +$225 XL · +$300 dual-tank city | City water only |
| Reverse osmosis, tank style | $800 | Drinking water at one tap — dissolved solids, nitrate, taste |
| Reverse osmosis, tankless | $900 | Same, no storage tank. City water only — never on a well |
| Pre-sediment filter | $500 | Grit and particulate. Wells mostly — city water rarely needs one |
| UV disinfection | $700 | Bacteria. Well water only |
| Salt-free conditioner | $3,050 | Scale control without salt. City water only; not a softener |
| Annual service | $199/yr tank RO home · $249/yr tankless | All three RO filters, water test, system check |

Your supply is chloraminated. Ordinary activated carbon reduces chloramine, but not thoroughly — genuine chloramine removal takes a full catalytic carbon tank. That is why the catalytic upgrade exists (+$150 on a standard build) and why we bring it up in Cedar Rapids rather than quietly installing carbon that underperforms on this specific water. Marion and Hiawatha run plain chlorine, where standard activated carbon is fine.
An $800 reverse osmosis system at the kitchen sink is often the entire answer, and it is the cheapest thing we install. You do not need whole-home filtration to stop your coffee tasting like a swimming pool. See why tap water tastes like chlorine.
That is hardness, and no filter fixes it. Carbon does not remove calcium and magnesium. You need a softener. This is the single most common mis-sale in the industry — a filtration system sold to someone whose actual problem is 18-grain water.
Filtration alone is rarely the right answer. Well water usually brings hardness, often iron, sometimes sulfur — which is why our well build is a dual-tank system at $3,450, with catalytic carbon already inside it. See well water treatment cost.
West Liberty and Atkins both operate municipal RO plants. In those towns whole-home filtration is usually unnecessary and an $800 final-barrier RO at the sink is the honest recommendation — sometimes nothing at all is.
We publish these numbers because almost nobody in this industry does — the national dealer networks route pricing through an in-home visit, so you cannot compare without booking appointments. See brands compared, Culligan cost in Iowa, or the full Eastern Iowa cost breakdown.

A carbon-only whole-home filtration tank is $1,150, or $1,450 with catalytic media. Bundled with a softener it is $2,500, or $2,850 with reverse osmosis added. Every price is all-in with installation by a licensed plumbing professional, taxes and a lifetime parts warranty.
A softener removes calcium and magnesium — the minerals that cause spots, film and soap that will not lather. A filter removes chlorine, chloramine, taste, odor and particulate. They are different jobs. If your complaint is spotted glassware, no filter will fix it; you need a softener.
Likely yes if chloramine matters to you. Cedar Rapids-supplied water is chloraminated, and ordinary activated carbon reduces chloramine but not thoroughly — genuine removal takes a full catalytic carbon tank. The upgrade is +$150 on a standard system. Marion and Hiawatha run plain chlorine, where standard activated carbon is fine.
For taste, odor, dissolved solids and nitrate at one tap, often yes — and it is the cheapest thing we install. It treats the kitchen tap, not the shower or the ice maker unless plumbed there. If your problem is hardness throughout the house, RO will not address it.
No. Iowa State University extension materials list reverse osmosis, distillation and anion exchange as the technologies that remove nitrate — carbon is not among them. The CDC notes that boiling does not remove chemical contaminants either; with nitrate, boiling concentrates it as water evaporates.
