PIONEER®OX is the first of its kind non-backwashing whole-house filtration solution that targets and improves the taste and odor of the water for peak flow rates up to 15 gpm, eliminating rotten egg smell, color/organics/tannins, Iron, Manganese and other heavy metals and water contaminants. 

PIONEER® OX features ENPRESS ATOMUS® MD1 inside technology, a proprietary filtration media solution for the water treatment industry specifically designed to simultaneously oxidize and adsorb organic and inorganic contaminants along with heavy metals that could be present in water. This patented and proprietary chemistry creates a unique oxidative media that does not add residuals to the water stream or create harmful disinfectant byproducts. Unlike typical oxidation agents, such as ozone, chlorine, peroxide, citric acid, or bromine, ATOMUS® MD1 is a “solid state” oxidizing agent. Overall system simplification is paramount in the usage of ATOMUS® MD1, eliminating an Airdraw or standard control valve head, the use of salt, or oxidation agents for regeneration.

With fast kinetics and EBCT (empty bed contact time) from 1–5 minutes depending on the agent that requires oxidation, PIONEER® OX can eliminate from water many difficult contaminants, including but not limited to:

  • Hydrogen Sulfide 
  • Color/Tannin/Organics 
  • Total Organic Carbon (TOC) 
  • Iron and Manganese 

And the further removal of:

Radium • Phosphate Silica Lead Uranium • Chromium Copper Zinc ArsenicLegionella Iron bacteria Fluoride

NSF/ANSI 61 certified and tested to USEPA TCLP and California Wet Tests, to provide maximum removal capacity and improved stability against pH upset preventing possible desorption of bound contaminants during use and in landfill conditions. This innovative POE (Point-of-Entry) filtration system provides FILTRATION EVERYWHERE TECHNOLOGY®.
