Bobrick PureDri - Technology

The Science of the Pure Hygiene Product Line

A breakthrough combination of patent-pending technologies and FDA-recommended technologies together

The PureDri Sanitizing Hand Dryer is a restroom device that protects hands with a blast of super-concentrated ionized air following the drying cycle, while providing constant sanitization to the room itself. Combining photocatalytic disinfection, germicidal irradiation, and dual waveband UV, our best-in-class technology sanitizes both air and surface for the purest, freshest environment possible.

Our technology eliminates harmful microorganisms using:

Germicidal UV
Hydroxyl radicals
Superoxide ions

Studies have long shown that viruses and bacteria live on surfaces and in the air. Recent articles document workplace safety and restroom concerns. Learn more about the proven efficacy of our clinically backed plasma in our expert-sourced white paper.

1. GERMICIDAL UV

As air flows through the plasma chamber and over the UV lamp all micro-organisms in the air are killed/inactivated.

Germicidal UV light changes the viruses’ RNA destroying their ability to reproduce.

2. SUPEROXIDE IONS

As air flows through the chamber the UV light reacts with the titanium dioxide catalysts causing a release of free electrons, they bond with oxygen to form Superoxide ions.

Superoxide ions bond with airborne particles (including microorganisms) causing them to sink as they are heavier and become attracted to surfaces beneath.

3. HYDROXYL RADICALS

As air flows through the chamber the UV light reacts with the titanium dioxide catalysts causing water vapor to be converted to highly reactive hydroxyl radicals (OH).

Hydroxyl Radicals (very strong oxidizing agents) cause oxidative damage to the viral particle eventually converting to CO2 and water.

DESIGNED TO REDUCE

RISK AT EVERY STAGE

PureDri emits a highly efficacious sanitizing plasma that is formed of hydroxyl radicals, and super-oxide ions and is proven to eliminate 99.8% of airborne and surface micro-organisms and substantially reduce unpleasant odors.

Across the spectrum of infectious airborne pathogens, PureDri’s patented technologies render the following inert:
