 Install and Confirm

Most complete it in an afternoon; results confirmed by retest, not just observation.

Three Contaminants, One Source

Orange staining, metallic taste, and rotten-egg odor are usually three separate contaminants

1. Dissolved Iron
2. Manganese
3. Hydrogen Sulfide

Arriving together because they share one source: groundwater moving through iron-bearing rock.

That's why a single-mechanism filter typically underperforms here.

Air Injection Oxidation, and Why It Handles All Three

A maintained air pocket oxidizes iron and manganese on contact converting dissolved compounds into solid particles.
Katalox media captures them before they reach a fixture.

Documented range:

  1. Iron up to 30 ppm
  2. Manganese up to 7 ppm
  3. Hydrogen sulfide — eliminated
  4. Natural pH increase, no chemical input
  5. Automatic backwash, no manual step required

Every Component Specified in Advance

  1. Iron Master AIO tank (1.0 / 1.5 / 2.0 cu ft)
  2. Pre-loaded Katalox media
  3. 1" programmable valve, 4-line LCD
  4. Air injection integrated into the valve
  5. Installation guide + video walkthrough
  6. Direct access to well water support

Six Months, Because Results Take That Long to Confirm

Long enough to run the system through its seasonal range and retest — not just observe.

Why Iron Needs a Dedicated System

A softener is built for calcium and magnesium different chemistry than iron.


Untreated iron reaching a softener fouls its resin within months. Air Injection Oxidation uses compressed air, not chlorine or permanganate, as the oxidizer and the air pocket recharges every backwash, removing the chemical-dependency problem entirely.

What the Rated Capacity Specifically Delivers

  1. Rated to 30 ppm iron, no chemical dependency

  2. Staining typically resolves within days

  3. Sulfur odor addressed by the same mechanism

  4. Full pressure maintained through the 1" valve

  5. Compatible with any SoftPro softener

  6. Lower long-term maintenance cost than chemical dosing systems

Section Image

What Coverage Specifically Includes

Limited lifetime warranty on the tank and core components.

60-day guarantee tied to measurable results, not defects
No proof of failure required to qualify for a refund.

What the Installation Point Specifically Requires

Installs after the pressure tank

The placement required for whole-house coverage. No chemical feed equipment or secondary pump needed. Most installs run two to four hours.

  1. Drain connection required for backwash

  2. Minimum flow: 5 / 7 / 10 GPM by tank size

  3. Standard 120V outlet required

  4. Phone support available throughout

What Each Certification Specifically Verifies

IAPMO confirms plumbing safety standards.

WQA verifies removal claims against independent data, not self-reported figures.

NSF confirms drinking-water material safety.

ISO 9001
confirms audited manufacturing quality.

ANSI confirms engineering compliance.

Section Image

The One Input That Determines Performance

Tank size is set by well pump flow rate, not household size.

A distinction worth stating because it's the most common sizing error.

Undersized: pressure drop.

Oversized: backwash can't clean the media.

Confirm Your Number Before Ordering

Tank Size Min. GPM Best For
1.0 CUFT 5 Most 1–2 bath homes
1.5 CUFT 7 Larger homes, higher iron
2.0 CUFT 10 High-volume pumps, irrigation

What Happens at Each Stage

  • Order— Sized by measured flow rate, ships in 1–2 days.
  • Install— Pre-programmed valve, typically one afternoon.
  • Confirm— Staining and odor typically clear within days; retest to confirm fully.

Why No Chemical Input Is a Structural Advantage

Chemical systems depend on a supply chain run out, and the problem returns immediately, independent of the equipment's condition.

The Iron Master's air pocket recharges every backwash, removing that dependency.
Oxygen oxidizes iron, Katalox captures it, backwash removes it

What the Mechanism Specifically Delivers

  1. Up to 30 ppm iron removed — ferrous, ferric, colloidal

  2. Up to 7 ppm manganese removed

  3. Hydrogen sulfide odor eliminated at the source

  4. No cartridges, no chemical refills, no supply chain dependency

  5. Natural pH increase, reducing pipe corrosion

Why the Sequence Isn't Optional

Iron reaching softener resin untreated causes progressive fouling

A documented failure mode, not a general caution.
Iron Master first, softener second, prevents it.
SoftPro softeners install in sequence without compatibility issues.

What "Protected for Life" Means in Practice

Limited lifetime warranty on the tank and control valve.
The 60-day guarantee is tied to measurable water quality change, not mechanical failure.

The distinction that matters if you're deciding whether to trust the claim.

A Mechanism-by-Mechanism Comparison

Greensand requires ongoing chemical dosing.
Birm requires pH above 6.8, excluding many acidic wells.
Chemical chlorination leaves disinfection byproducts requiring a second filter.
Katalox with air injection avoids all three limitations.

Where the Documented Differences Are

  1. 1" valve maintains pressure competitors' smaller ports restrict

  2. Iron, manganese, and sulfur addressed by one mechanism, not three

  3. No chemical maintenance requirement

  4. Lifetime warranty vs. most competitors' 1–5 year cap

  5. 60-day guarantee — uncommon in this category
