Air Steril
Our French site will be coming soon.


The air all around us contain microorganisms - bacteria, viruses, moulds, fungi and volatile organic compounds. Some airborne microorganisms create offensive odours, other spread infections and others develop mouldy conditions. They can grow at a rapid rate. One bacteria can grow to 17 million in 8 hours. To appreciate this take a clean cloth, wet it, fold it 2 or 3 times, wait 30 minutes and it becomes smelly. In enclosed spaces airborne microorganisms are deposited on surfaces where they continue to grow creating odours and spreading infections. In such a way airborne and surface microorganisms develop unhygienic conditions which need to be freshened, cleaned and disinfection.
Standard room cleaning and disinfecting procedures offer just 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 their source - the microorganisms in the air and on the surfaces. By their nature washrooms represent the major hygiene problem in public and private places. Faecal coliform contains a great deal of harmful microorganisms such as E-coli, ear infections, dysentery, typhoid fever, viral and bacterial gastroenteritis and hepatitis A. After using the facilities, many people do not wash their hands compromising the hygiene and spreading the problem inside and outside the washroom. Studies by the London School of Hygiene and Tropical Medicine showed that one is six mobile phones carried traces of faeces.
AirSteril offers a permanent 24/7 system which guarantees to eliminate odours and control infections in any enclosed space. 
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.

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.
It was first used commercially 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.
An AirSteril unit uses five independent mechanisms. Each mechanism can be individually controlled to create tailor-made solutions to meet specific air purification requirements.
The five technologies are:
  • Germicidal irradiation (UV light)
  • Heterogeneous catalysis
  • Triatomic oxygen sterilization (ozone)
  • Plasma quatro
  • Super oxide ion generation
Germicidal irradiation kills micro-organisms by disrupting their DNA and preventing reproduction.
Dual waveband UV technology transforms oxygen into a reactive state. Superoxide ions and hydroxyl radicals produced in this process are some of the strongest oxidisers known, stronger even than ozone. The negatively charged superoxide ions work by electrically charging air contaminates as small as 0.01 microns and causing them to form clusters, thus assisting removal from the air and aiding the other processes.
Triatomic oxygen (ozone) produced via a catalyst in the lamp (quartz) eliminates bacteria, viruses, fungi and VOCs in the air as it passes through the AirSteril unit.
The air leaving the unit holds plasma quatro which consists of a mixture of activated oxygen, triatomic oxygen and superoxide ions. These interact with each other supplying a very efficient purification of the air and all exposed surfaces close by. This unique, ground breaking AirSteril process is many times more efficient than ozone or UV light working alone.
