There are several types of aeration systems.
Two good examples of air injection are the SoftPro Iron Master and the IronBreaker III.
With all aeration systems, air is injected into the water, counting on the fact that air is made up of 21% oxygen. 
Oxidizing the water reduces dissolved minerals such as iron and manganese and removes sulfur. It does not kill any bacteria.
Aeration systems reduce but do not eliminate the contaminants, in contrast to pure ozone and pure oxygen systems that are 100% effective. 

SoftPro Iron Master

The SoftPro® Iron Master AIO Water Filtration System uses Air Injection for optimal performance.

Removes iron up to 30 ppm, manganese up to 7 ppm, sulfur up to 5 ppm, zinc and copper, with filtration down to 3 microns

Long service life
Reliable performance

This filter works by supplementing oxygen to incoming water via a bubble of compressed air. The oxygenated water then passes through a specialized filter bed. As water passes through this AIO designed iron the oxygen is depleted, the media attracts iron, sulfur and manganese. The system will then automatically start the regeneration process to backwash out the iron trapped in the media bed and replenish the oxygen supply.

Engineered with unique MnO2 coating technique on ZEOSORB®, this Katalox technology far exceeds the performance of Birm, Greensand Plus, and Manganese Greensand. It is the highest coating of Mn02 in the industry (10%) and creates the most effective oxidation and co-precipitation of contaminants.


Both the SoftPro Iron Master and the Iron Breaker III are single-tank systems.

Iron Breaker III

The IronBreaker III is good for cabins, single residents, or situations with minimal water usage. Aeration systems can remove iron and sulfur smell, but cannot kill iron bacteria. If your water has the sulfur odor of “rotten eggs”, if there are iron stains on your sinks and bathtubs, if you use large amounts of soap to clean dishes, wash your hair or suffer the “orange hair” effect sometimes caused by iron water, you probably have water that can be successfully treated with an IronBreaker III iron and Hydrogen Sulfide (H2S) removal system. Left untreated, these minerals will cause yellow/brown stains on fixtures and clothing, clogged pipes and appliances, shortened service lives for dishwashers, washing machines and water heaters, all adding to the cost of maintaining appliances while increasing the amount of energy consumed in your home. Whether it’s rust stains in your sinks and laundry, or the “rotten egg” smell of H?S when you turn on a tap, your water problems can cause you and your family more than embarrassment and frustration. Iron and H?S can damage your fixtures and plumbing, discolor your laundry or create unpleasant odors in drinking water and showers.

Until recently, the most common solution for problem iron and H2S water involved the use of harsh chemicals and complicated equipment, requiring regular care and service by the homeowner or water treatment professional. The IronBreaker III now offers the “natural” solution for removing iron and H?S. A proven patented technology that uses natures own oxidation process to eliminate iron and H?S without chemicals, without air compressors, without aerators and without external ventures’. Using natures own oxidation process, leaving you with fresh, clean, odor free water throughout your home.

All of your water using appliances will lead longer lives. Dishwashers, automatic washers and, of course, your water heater will benefit from having reduced iron and H?S, adding years to the life of major appliances and postponing expensive repair and replacement. Hot water heaters, washing machines and dishwashers using iron laden, hard water can wear out 30% faster, while consuming more energy than an appliance using iron free, H?S free, soft water. In the bathroom there will be no more iron stains or rotten egg odor. Soap and shampoo will lather better. Hair and skin will feel noticeably cleaner. And when used with a water softener, your iron free, odor free water will be soap scum free, without mineral deposits to clean off sinks, showers, tubs and toilets. In the laundry, without iron or H?S in the water, clothes will be whiter and brighter. Plus, they will last longer. Add a water softener and increase the life of clothing, towels and linens by up to 33% and add even longer service life to your appliances. In the kitchen, there will be no iron stains on the sink, no objectionable odor while running water for cooking, cleaning or drinking. Dishes will clean more easily and, by adding a water softening unit, your dishes will be spot free without the film glasses get when etched by mineral-laden water.

How the IronBreaker III Works

The IronBreaker III stores a “bubble” of air, compressed by your well pressure, within the media tank. As your water passes thru the air, the iron or H?S is converted to a particle which is then trapped by the catalytic filter media in the tank while the air “bubble” is gradually consumed by the passing water.

For regeneration, the unit first “backwashes” itself, removing any iron particles it has trapped. The system then replenishes the “air bubble” by drawing in atmosphere, temporarily emptying the tank of all water and transferring oxygen molecules into and on the surface of the media bed where all oxidation occurs. The system then returns to the “service” position, again filtering your water. Add the ozone generator option and the IronBreaker III system is automatically sanitized during the regeneration process.

Benefits of the IronBreaker III System

The IronBreaker III controls the iron and H?S is your homes water and:


  • Low cost
  • Simple single-tank system
  • Significantly reduces color, flavor, odor, staining


  • Reduces, but does not fully eliminate contaminants
  • Will not treat hardness, calcium, or arsenic
  •  Does not kill bacteria
