Advanced Oxidation Technology
Photohydroionization and REME HALO, explained.
Our products mimic Mother Nature's cleaning process by releasing hydrogen-peroxides into the air. Advanced Oxidation Technology (AOT) was developed over 20 years ago, and since then, more than one million AOT cells have been in use all around the globe.
The patented Photohydroionization® PHI-Cell® and the patent-pending REME Halo® both produce hydro-peroxides to actively cleanse the air. Both technologies below are manufactured by RGF Environmental Group Inc. and sit inside the nine units on our products page.

PHI-Cell® technology
Four stages inside a PHI-Cell.
PHI-Cell® technology has been used globally for over 20 years with a perfect safety record.
It is the cell inside units like the CML Commercial PHI Unit, the one Fisher Brothers tested for 18 months in its own building.
01
UV light meets the catalyst
A broad-spectrum, high-intensity UV light is targeted on a hydrated quad-metallic catalyst surface. The surface is covered with a proprietary quad-metallic and hydrophilic coating.
02
Plasma forms
The UV light reacts with the catalyst and moisture to produce an advanced oxidation plasma of hydro-peroxides, superoxide ions and hydroxide ions.
03
The pollutant is eliminated
These friendly oxidizers come into contact with the pollutant and eliminate it.
04
They revert
Once they have done that, the oxidizers revert back to oxygen and hydrogen.

REME HALO® technology
The cell that works inside the duct.
The REME HALO® is RGF's in-duct HVAC unit. This hydrogen peroxide vapor is excellent at killing germs, reducing volatile organic compounds, and eliminating unwanted odors, and it has the added benefit of reducing airborne dust and particles.
- The cell
- An electromagnetic energy cell creates the plasma.
- The plasma
- Ionized hydro-peroxides (H2O2), a friendly oxidizer made from oxygen and humidity.
- The dust
- Bi-polar ionization makes particles clump into larger, heavier ones that drop out of the air or are caught by your filter.
See the REME HALO® and its spec sheet on the products page.

Norovirus and MRSA protection plans
These AOT cells have been specified in the Norovirus and MRSA protection plan of America's largest restaurant chains, hotel chains, theme parks, cruise lines, public schools, hospitals.
More than 50% of all major office buildings have contaminated heating, ventilation, and air conditioning systems (HVAC).
That is the problem an assessment starts with: an engineer reads your fan schedule and your HVAC before any unit is chosen.
