Iron Filter Cost for Well Water (2026 Price Guide)

If you have iron in your well water, you have likely asked yourself: "What is this really going to cost me to fix?" Here is the straight answer. Our air injection iron filters with Katalox Light (the filter media that catches the iron) are $2,495 to $3,495 with free shipping to the lower 48 states. Add about $800 for a plumber to put one in, and the installed total comes to about $3,300 to $4,300.

Prices as of October 23, 2026. Every size takes out up to 30 ppm of iron; the size comes from your household and your well.

Why are prices all over the board?

Four things set the price: the tank, the control valve, the media inside, and the company you buy from. A cheaper filter usually saves its money on the first three, the parts you cannot see.

• The tank. Ours are Vortech tanks made in Ohio. We tried cheaper tanks from Mexico once, and they sprang pinhole leaks within 2 to 3 months.
• The control valve. The valve on top runs the cleaning cycle. The better the valve, the more it costs. Ours is the Fleck 2510 AiQ, a digital air injection valve; a basic filter often has a mechanical one.
• The media. A basic filter with Birm in it does a pretty good job for a while. Here in Maryland, where we have some of the worst iron well water in the country, we tried greensand, Birm and carbon. When Katalox Light came along, it blew everything else away. It costs a little more.

A cheap filter sold online

Search online and you will find iron filters from around $895 for a 1 cubic foot unit, which is very small. That might work for one person who uses very little water. A family of 4 to 8 people needs a much larger tank, like our 2.5 cubic foot (a 13 by 54 inch tank), and yes, it costs more. The other difference is who answers the phone: we are open 7 days a week, and you talk to me.

The high-end local dealer

Call a company like Culligan, RainSoft or EcoWater, and the quotes run from $5,000 to $10,000. The person who comes to your house is usually a commissioned salesperson, and he usually gets 20% of what he sells. If a dealer quoted you a name brand, see what an Iron Curtain costs and what an IronBreaker costs.

Buying direct at wholesale prices

We are a wholesale distributor, and we sell to homeowners at wholesale prices. That is how the same kind of filter comes in at $2,495 to $3,495, and under the low end of a dealer quote even after a plumber's $800.

I talk through iron filter prices in the video.

The prices I give for our filter on camera ($1,995 and $2,195) were the prices when the video went up in February 2026. Today's prices are in the table at the top of this page.

What the price includes

Every size ships complete, with free freight to the lower 48 states; orders to Alaska and Hawaii pay extra shipping. It arrives on a pallet by liftgate truck.

What ships:

• The Vortech mineral tank, empty
• The Fleck 2510 AiQ control valve with its stainless bypass valve
• A fill funnel
• The Katalox Light, in separate bags, loaded into the tank at install

Drain tubing is not included; your plumber sizes the drain line for the backwash flow and the length of the run. The tank ships empty because a full tank is too heavy to ship without damage. The 2.5 tank weighs about 30 pounds, and the media runs about 50 to 60 pounds per cubic foot. The valve carries Pentair's 5-year warranty, and the tank a 10-year warranty.

What installation costs with a plumber

A plumber puts one in for about $800, and it takes about 2 to 3 hours. Plumbing it in means connecting an inlet and an outlet. The drain line is the part that takes planning. It runs to a floor drain, standpipe or utility sink, with an air gap. The valve also needs a standard outlet nearby.

I recommend having a plumber put it in, and I'm a phone call away for your plumber. If you'd rather do it yourself, text me with any questions. The box has little install guidance, because manufacturers expect a plumber or a dealer to install it; the steps are in how to install an iron filter.

I also recommend a 20 inch Big Blue sediment filter with it, $195, so add that to the plumber's list.

What the filter costs to own

After install, the only cost is new Katalox Light every 6 to 8 years. There is no salt, no chemicals and no yearly service. The filter cleans itself with an automatic backwash. When the media is spent, the tank is dumped out and refilled with fresh Katalox Light, and the tank stays in service.

The media prices are today's, from our 1 cubic foot bags at $325 and 1/2 cubic foot bags at $225. Media can last longer with light use; some people call me in the 10th year to order more. The media change itself is in iron filter maintenance.

When your water needs more equipment

A rotten egg smell or manganese adds nothing to the price. A low pH, hard water, very high iron or iron bacteria can add equipment. Here is what each one adds.

When a neutralizer goes in, a softener usually follows, because the neutralizer's limestone adds hardness to the water. That is why the low pH package has all three, and buying them together saves a few hundred dollars. A neutralizer on its own is priced in acid neutralizer cost.

Can a softener remove the iron instead?

A softener takes out low levels of iron, but the iron wears out its resin. For iron, I recommend the iron filter. A softener costs less up front, but you carry salt home for as long as you own it; with the iron filter there is no salt. If your water is also hard, the softener goes after the iron filter, so it gets water with the iron already out.

The full side by side is in iron filter vs water softener, and every way to get iron out, with what each costs over 10 years, is in how to remove iron from well water.

Match the filter size to your water

Your water and the people in your house set the size. The square footage does not. A 2,000 square foot house and a 20,000 square foot house can need the same filter. What I look at:

• Iron and pH. Iron comes out best at a pH around 8. Wells can have anywhere from 0.3 ppm to 50 ppm of iron.
• People and bathrooms. More people running more water at once need a bigger tank.
• Your well's flow. The bigger tanks need more flow from the well to clean themselves. On a weaker well, I can lengthen the backwash.

If you don't have a lab report yet, our certified well water test is $199 and shows iron, manganese, pH and hardness from one sample. Size by size, the numbers are in the iron filter sizing guide.
