TiO2 Photocatalytic Oxidation Technology

AIRBORNE Allergy Relief Lights will continue to decompose offending contaminants and VOCs without loss of effect.

There are no chemicals to be used up, no absorbents like activated charcoal to get saturated or filters that need replacement.


As a catalyst, a TiO2 catalyst will work tirelessly and continuously to help scrub the atmosphere in your Clinic, Factory, Food Processing plant, Hatchery, Private Home, Indoor, or Office area, Outdoor etc, etc, etc!

Natural light is both a source of life and destruction. The sun’s powerful ultraviolet rays continually cause chemical reactions - activating powerful redox reactions in which atoms are chemically changed. These reactions have been extensively studied for well over three decades as researchers look for ways to turn destruction into beneficial applications and are the bases of the Photocatalytic Oxidation (PCO) process.


A single nanoYo coated bulb or tube can eliminate contaminants for up to 200 cubic feet of space!

To be totally effective, the bulb only needs to be turned on and exposed to the air. It can not destroy all contaminants if enclosed within a fixture as this limits the Air Movement needed for PCO activity for applications where the light bulb is shielded an enclosed fixture.


Photocatalytic oxidation converts toxic compounds, even carbon monoxide and nitrous oxide, into benign constituents such as carbon dioxide, water and dilute mineral acids without wearing out or losing its effectiveness. Airborne Light technology uses photocatalytic oxidation (PCO) to eliminate a wide range of chemical and biological contaminants. Unlike adsorbents, photocatalysts chemically destroy these contaminants without producing harmful chemical residue, such as ozone.

Airborne lights uses one of the most popular photocatalystic materials - titanium dioxide (TiO2), which offers a combination of stability, photoactivity, relatively low-cost, and non-toxicity. Titanium dioxide is unaffected by acids, bases, or organic solvents, and stable up to several hundred degrees.

PCO takes place when light (sunlight or electrical) activates a semiconductor photocatalyst in the presence of oxygen and moisture. Activation of the catalyst generates hydroxyl radicals and super-oxide ions, powerful oxidising species that attack and break down organic compounds. In the photocatalytic process, this light can be supplied by ambient sunlight or electric lamps.

For industrial applications, UV back lights or arc lamps are used; however, ordinary indoor fluorescent lighting typical produce enough energy to activate the catalyst. Fluorescent lamps are ideal in indoor applications.  In outdoor applications, direct or diffuse sunlight is effective, thus the process functions on clear or cloudy days.

Photo activated reactions on a titanium dioxide particle. The TiO2 particles must be accessible at the surface of the Ultra-Thin-Film for contact with the air and adsorbed contaminants.

H o w I t W o r k s :

The titanium dioxide Ultra-Thin-Film on the surface creates a photocatalytic reaction when exposed to the fluorescent light produced by the bulb. This reaction releases electrons, or negatively charged particles. At the same time, a positively charged hole is formed in its place. This combination of negative and positive creates a very strong oxidizer called the hydroxide radical.

Odours that come into contact with the positively charged holes are broken down by these oxidisers into odourless compounds.D

iRandom Practical Test Results













Direct sunlight is really both a source of life and also it’s destruction. The sun’s powerful ultraviolet rays continually cause chemical reactions - activating powerful redox reactions in which atoms are chemically changed. These reactions have been studied for well over three decades as researchers look for ways to turn destruction into beneficial applications. Photocatalytic oxidation (PCO) is an emerging technology where water or air is purified by the chemical action of light.

Photocatalytic oxidation converts toxic compounds, even carbon monoxide and nitrous oxide, into benign constituents such as carbon dioxide, water and dilute mineral acids without wearing out or losing its effectiveness. The Airborne technology uses photocatalytic oxidation (PCO) that will eliminate a wide range of chemical and biological contaminants, and unlike adsorbents, photocatalysts chemically destroy these contaminants without producing harmful chemical residue...such as ozone.

The Airborne Allergy Free Lights will begin to clean the air after five - ten minutes from being switched on. The longer the lamp is left on the greater the absorption rate. Tests have shown that after 1.5 hours the Airborne PCO process consumed more than 95% of the odours in the air.
