SCIENTIFICALLY PROVEN PRODUCTS. SPECIALISTS IN AIR AND SURFACE PURIFICATION
The air around us contains microorganisms, bacteria, viruses, moulds, fungi and volatile organic compounds. Some airborne microorganisms create offensive odours, other spread infections and others develop mouldy conditions.
In enclosed spaces airborne microorganisms are deposited on surfaces where they continue to grow creating odours and spreading infections. Standard room cleaning and disinfecting procedures offer temporary solutions, as soon as an area is cleaned/disinfected the microorganisms return and so do the smells and risks of infection. Many places use fragrances which only mask the odours and do not kill the source, the microorganisms, in the air and on surfaces.
SCIENTIFICALLY PROVEN TO REDUCE ODOURS AND CONTROL BOTH AIRBORNE AND SURFACE BACTERIA AND VIRUSES
Washrooms represent a major hygiene problem in public and private places, faecal coliform contains a lot of harmful microorganisms such as e.coli and bacteria which can cause ear infections, dysentery, typhoid fever, viral and bacterial gastroenteritis and hepatitis A. After using the facilities, many people do not wash their hands properly, compromising hygiene and spreading the problem inside and outside the washroom. Studies by the London School of Hygiene and Tropical Medicine showed that one in six mobile phones carried traces of faeces.
In September 2009, the Health Protection Agency's laboratories at Porton Down performed efficacy testing of the AIRsteril MP20 unit's ability to reduce aerosol and surface microbial contamination. The tests showed a reduction of airborne microorganisms of up to 98.11% within five minutes of exposure and a reduction of surface contamination up to 59.47% in one hour, the surface tests included MRSA. The full HPA report is available free of charge on request.
Ultraviolet light was discovered in the late 18th 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.
It was used commercially first in the USA in the 1920's to control TB outbreaks, then when antibiotics were developed it fell out of favour mainly because direct exposure to UV-C can be harmful and its use is subject to regulation. However, the effectiveness of antibiotics is being challenged by resistant pathogens so the interest in the use of UVGI has increased.
An AIRsteril air purifier utilises dual lamp ultraviolet light operating at the peak UVC wavelengths, creating germicidal irradiation, hydroxyl radicals, superoxide ions, plasma quatro and optional Ozone. This process freshens the air by killing airborne pathogens, viruses, bacteria, fungi, mould spores, dust mites, 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.
