EC4 OxyTech™
A fully automatic, chemical-free whole-house filter that eliminates the odors and stains caused by iron, sulfur, and manganese in your water — using nothing but oxygen.
EC4 OxyTech™ — how it works.
The EC4 OxyTech tackles rotten-egg odor and rust stains without any added chemicals. Incoming water is charged with oxygen, which transforms dissolved minerals and gases into filterable particles that are then trapped and flushed away automatically.
Compressed aeration
Water enters an aeration chamber and becomes highly oxygenated as it passes through.
Oxidation
The oxygen converts dissolved iron, manganese and hydrogen sulfide into physical particles.
Filter & backwash
A multimedia bed traps the particles, then the system backwashes itself at set intervals.
