HISTORY OF OUR TECHNOLOGY

Ultraviolet light was discovered in the late 19th century. There are several types of UV, UV-A and UV-B occur naturally from the sun's rays, AIRsteril technology generates UV-C otherwise known as ultraviolet germicidal irradiation (UVGI). UGVI is effective in destroying the nucleic acids in microorganisms so that their DNA is disrupted by the UV radiation, leaving them unable to perform vital cellular functions.

UVGI was first commercially used in the USA in the 1920's to control TB outbreaks, then it fell out favour when antibiotics were developed. However, the effectiveness of antibiotics is being challenged by resistant pathogens so the interest in the use of UVGI has recently increased worldwide.

Ozone is highly reactive, breaking down the cell walls of bacteria and other microorganisms, then reverting to oxygen. Ozone gas was discovered in 1840 by Christian Schonebein, one of the first uses was in water disinfection, with ozone generators developed for medical use through the 20th century. Ozone can be generated by multiple methods, and it is essential that levels are precisely controlled.

An AIRsteril air purifier utilizes a combination of the most effective and refined air and surface purification technologies to produce the best possible results. Every element of our process is adjusted across our product range to ensure the best results with varied chamber size, catalyst area and position, lamp output, dwell time and flow rate for each specific environment. In each unit, our dual ultraviolet light lamps operate at the peak UVC wavelengths in the presence of Ti02 catalyst plates enclosed within our reflective internal cleaning and purification chamber creating germicidal irradiation, PCO – photocatalytic oxidation, hydroxyl radicals, superoxide ions, optional ozone with air leaving the unit as plasma quatro. This process freshens the air by killing airborne pathogens, viruses, bacteria, fungi, mould spores, allergens and by decomposing odours and harmful gases.

HOW TECHNOLOGY WORKS

A combination of technologies work together

Internal:

• Germicidal Irradiation
• PCO – Photocatalytic Oxidation
• Dual waveband UV

Transmitted Technology (Plasma Quatro):

• Superoxide Ions
• Targeted Ozone
• Purified Air

Internal

• Germicidal Irradiation by dual UV light (Ultraviolet) kills microorganisms (bacteria, viruses and mould) by disrupting their DNA and removing their reproductive capabilities.
• PCO – Photocatalytic Oxidation, UV reacts with our Catalyst (Ti02) to form highly reactive but short-lived oxidising Hydroxyl Radicals (OH) which break down Volatile Organic Compounds (VOCs).
• Interaction of the dual UV wavebands with the TiO2 heterogeneous catalyst both creates and breaks down Oxygen molecules transforming Oxygen into a highly reactive state of Ozone and Superoxide Ions which leave the unit as “Plasma Quatro”.

Transmitted Technology

• The negatively charged Superoxide Ions charge airborne contaminants causing them to cluster together and fall from the air as they become too heavy, aiding all other processes. This can remove airborne particulates down to 0.0001 microns, that’s better than any HEPA filter.
• Targeted Ozone produced via the specialist lamp gets the hardest to the hardest to reach areas breaking down contamination in the air and on exposed surfaces. Ozone damages the cell wall of microorganisms stopping reproduction and destroying the cell.
