Why Use RGF’s REME-HALO®Zero?

The REME HALO® Zero utilises RGF’s proprietary aGHP-Cell™ technology to recreate nature’s process of purifying the air and is verified Zero Ozone to UL 2998.

When installed into the existing air conditioning or heating system air ducts, the REME HALO® Zero produces low level airborne Hydrogen Peroxide that is distributed through the HVAC system and into the conditioned space.

Unlike passive air technologies, which need pollutants to pass through the unit for purification or filtration, the REME HALO® Zero uses active cleaning technology that directly targets pollutants.

Every time a hydrogen peroxide molecule comes into contact with bacteria, viruses, mould spores, and odours it quickly breaks them down, reducing air quality contaminants at the source. The system also passes a charge off to all the dust, dander, pollen, and allergens in the air, which causes them to stick together. The increase in size will make your existing filter equipment more efficient at capturing these airborne particles.

It operates silently and continuously, so once it’s installed, the only thing you’ll notice is how fresh your home smells – and how comforting it is to help protect everyone around you.
