Below are the three whole-house chemical-free technologies available for oxidizing dissolved minerals and treating water on Whidbey.
The oxygen system is salt-free and eliminates iron, manganese, sulfur, hardness, and even arsenic — all the problems we have here on the island — for the lowest long-term price and the least maintenance.

Three Effective Water Treatment Options

             There are several ways to remove iron and other undesirable elements from water. Details are available at

  • Green sand and straight filtration methods are semi-effective, but do not remove everything 100%, and they will not kill iron bacteria.
  • Chlorine and other forms of chemical injection work, but involve the use, handling and purchase of toxic chemicals.
  • Aeration alone can be effective, but the percentage of oxygen in air is small. Aeration with the addition of ozone is significantly more effective; this is the method used with the iron breaker.
  • Ozone is highly effective, and a pure ozone system will remove chemicals, minerals, sulfur smells, and will kill iron bacteria. (Additional systems cost extra, such as treatment for tannin, hardness, pH, arsenic, silica, etc.)
  • Oxygen systems are by far the most effective; the EcoSmarte oxygen system will remove everything at the lowest long-term cost and with the least amount of on-going maintenance. (Any additional systems required are included at no extra cost.)
