2026 Well Water Treatment System Pricing: Complete Table

Every system listed below ships free to your door and includes the tank, valve (where applicable), media, bypass valve, and fittings. No hidden fees. Prices are current as of March 2026.

1. Acid Neutralizer Cost (pH Correction)

An acid neutralizer raises your water's pH by passing it through calcite (calcium carbonate) media. If your water tests below 7.0 pH, this is the system that protects your pipes, fittings, and appliances from corrosion damage. For a complete explanation, see our full Acid Neutralizer Cost Guide.

Current Pricing by Size and Type

What's Included

• Vortech tank with built-in distributor plate
• Clack or Fleck valve (depending on type)
• Calcite media (pre-loaded)
• Bypass valve and fittings
• Free shipping to your door

Ongoing Costs

Calcite refills: $145 per 50-lb bag. Most homes use 1 to 3 bags per year depending on pH level and water usage. A home with pH of 6.5 and average usage will typically go through about 1.5 bags annually ($200 to $220 per year). Very acidic water (below 5.5) may also need FloMag ($225 per 50-lb bag) blended with the calcite for additional pH correction.

5-Year and 10-Year Total Cost

For a typical 2.5 CF non-backwashing unit at $1,495 with ~$200/year in calcite:

• 5-year total: $2,495
• 10-year total: $3,495

2. Iron/Sulfur Filter Cost

An iron filter removes dissolved iron, hydrogen sulfide (rotten egg smell), and manganese from your well water. The system uses air injection oxidation (AIO) with Katalox Light media, requires zero chemicals, and backwashes automatically. For the full pricing breakdown, see our Iron Filter Cost Guide.

Current Pricing by Size

What's Included

• Vortech tank (no gravel underbed needed)
• Fleck 2510AIO air injection valve
• Katalox Light media (pre-loaded)
• Bypass valve and fittings
• Free shipping

Ongoing Costs

This is where the iron filter stands apart from every other treatment method. Annual maintenance cost: $0. The system backwashes itself automatically every few days using your home's water pressure. There are no chemicals to buy, no cartridges to replace, and no salt to refill. The Katalox Light media typically lasts 6 to 8 years before needing replacement.

When media replacement time does come (around year 7), expect to pay approximately $300 per cubic foot for Katalox Light.

5-Year and 10-Year Total Cost

For a typical 2.0 CF system at $1,995:

• 5-year total: $1,995 (no ongoing costs)
• 10-year total: $2,595 (one media replacement at ~$600)

3. Water Softener Cost

A water softener uses ion exchange resin to remove calcium and magnesium (hardness minerals) from your water. If your water tests above 7 grains per gallon (gpg) hardness, a softener will eliminate scale buildup on fixtures, extend appliance life, and improve soap performance. For the full breakdown, see our Water Softener Cost Guide.

Current Pricing

What's Included

• Resin tank with 10% crosslink resin (lasts longer than the standard 8% most competitors use)
• Fleck digital metered valve
• Brine tank with safety float
• Bypass valve and fittings
• Free shipping

Ongoing Costs

Salt: A 40-lb bag of softener salt costs approximately $6 to $8 at any hardware store. Most homes use 1 to 2 bags per month, putting annual salt cost at roughly $100 to $150 per year.

Resin: The 10% crosslink resin in MAW softeners lasts 10 to 15 years with proper maintenance. Standard 8% resin (used by most competitors) typically lasts only 7 to 10 years. When resin replacement is eventually needed, expect $250 to $350.

5-Year and 10-Year Total Cost

For the Fleck 5600SXT at $1,895 with ~$125/year in salt:

• 5-year total: $2,520
• 10-year total: $3,145

4. Carbon Filter Cost

A whole-house carbon filter removes chlorine, chloramines, volatile organic compounds (VOCs), pesticides, and taste or odor issues. If your water has a chemical taste, earthy smell, or elevated tannins, a carbon filter addresses it at the point of entry. For a deep dive, see our Complete Carbon Filter Guide.

Current Pricing

Ongoing Costs

Non-backwashing: Carbon media typically lasts 3 to 5 years before needing replacement (~$150 to $250 per cubic foot).

Backwashing: The automatic backwash extends media life to 5 to 7 years by preventing channeling and keeping the carbon bed fresh.

5-Year and 10-Year Total Cost

For a typical 1.5 CF backwashing system at $1,895:

• 5-year total: $1,895 (media may not need replacement yet)
• 10-year total: $2,345 (one media change at ~$450)

5. UV Disinfection System Cost

A UV system kills 99.99% of bacteria, viruses, and other microorganisms by exposing water to ultraviolet light. Every home on well water should have one, according to the EPA. If your water has ever tested positive for coliform bacteria, a UV system is not optional. For the full pricing analysis, see our UV Water Treatment System Cost Guide.

Current Pricing

Ongoing Costs

UV bulb replacement: The bulb needs to be replaced annually. The VH200 replacement bulb (S810RL) is $145. The VH410 replacement bulb is $160. This is the only annual cost.

Quartz sleeve: The protective sleeve should be replaced every 2 to 3 years, costing approximately $50 to $70.

5-Year and 10-Year Total Cost

For the VH200 at $895 with ~$150/year in bulbs and sleeves:

• 5-year total: $1,645
• 10-year total: $2,395

6. Sediment Filter Cost

A sediment filter traps sand, silt, rust particles, and other physical debris before water enters your home. It protects downstream equipment (iron filters, softeners, UV systems) and prevents clogged faucet aerators and showerheads. For more details, see our Complete Sediment Filter Guide.

Current Pricing

Ongoing Costs

Cartridge replacement: Big Blue cartridges run $15 to $25 each and need replacement every 3 to 6 months depending on sediment levels. Annual cost: approximately $40 to $80. The Rusco spin-down filter has a reusable screen that just needs periodic cleaning.

5-Year and 10-Year Total Cost

For the 20" Big Blue at $195 with ~$60/year in cartridges:

• 5-year total: $495
• 10-year total: $795

7. Well Pressure Tank Cost

A pressure tank stores pressurized water so your well pump does not have to run every time you open a faucet. If your pump is short cycling (turning on and off rapidly), your tank's bladder has likely failed. Replacing it reduces pump wear, stabilizes pressure, and can lower your electricity bill. For the full pricing breakdown, see our Pressure Tank Cost Guide.

Current Pricing

Ongoing Costs

$0 per year. Pressure tanks have no media, no consumables, and no moving parts. A quality bladder tank lasts 10 to 15 years or longer. The only maintenance is checking the air charge annually with a tire gauge (takes about 30 seconds).

8. Reverse Osmosis (Drinking Water) Cost

A reverse osmosis (RO) system is an under-sink unit that produces purified drinking water by forcing water through a semi-permeable membrane. It removes virtually all dissolved contaminants including nitrates, arsenic, lead, fluoride, and total dissolved solids (TDS). RO is specifically for your kitchen faucet, not a whole-house solution. For homes with elevated arsenic, see our complete guide to arsenic in well water for whole-house and point-of-use treatment options.

Current Pricing

Ongoing Costs

Pre-filters: Replace every 6 to 12 months, approximately $30 to $50 per set.

RO membrane: Replace every 2 to 3 years, approximately $80 to $100.

Estimated annual cost: $50 to $80.

5-Year and 10-Year Total Cost

• 5-year total: ~$945
• 10-year total: ~$1,295

9. Package Deals and Bundle Pricing

Most homes need more than one system. If your water test shows low pH plus hard water, for example, you need both an acid neutralizer and a water softener. Buying them together saves money compared to purchasing separately.

Current Package Pricing

Additional package configurations are available. If you need a combination not listed here, call Aidan at 800-460-5810 for a custom quote. Aidan will review your water test results and recommend exactly what you need, nothing more.

10. Common Scenarios: What Will YOUR System Cost?

Most homeowners do not need every system listed above. Your water test determines what you need. Here are the four most common well water treatment scenarios with real cost estimates.

MAW Direct Pricing vs. Dealer and Plumber Pricing

The water treatment industry has a significant markup problem. Local dealers (Culligan, RainSoft, EcoWater, Kinetico) and plumbing companies typically charge 2x to 4x what the equipment actually costs. That price includes commissioned salespeople, showroom overhead, truck rolls, and installation labor, whether you need it or not.

Mid Atlantic Water cuts out every middleman. We ship the same professional-grade equipment directly to your door at wholesale pricing. Here is what that looks like in practice:

The savings come from MAW's direct-to-consumer model: no showrooms, no commissioned sales team, no truck fleet, no installation crews. That overhead gets passed to the customer at traditional dealers. MAW's model eliminates it entirely, putting those savings back in your pocket.

10-Year Total Cost of Ownership: Every System

Upfront price is only part of the picture. Some systems cost almost nothing to maintain over their lifetime, while others have meaningful annual expenses. This table shows the true long-term cost of each system.

The Cost of NOT Treating Your Well Water

It is tempting to put off water treatment because of the upfront cost. But untreated well water causes progressive damage that costs far more in the long run:

A $1,495 acid neutralizer prevents $10,000+ in pipe damage. A $1,995 iron filter eliminates hundreds of dollars per year in staining costs. A $1,695 pressure tank prevents a $3,000+ pump replacement. In nearly every case, the treatment system pays for itself within the first few years by preventing damage that would otherwise be inevitable.
