SteriLumen UT-225 UVC Air sterilizing unit
STERILUMEN UT-225 is an air sterilization device that uses advanced UVC technology to neutralize the bacterial and viral charge of the air in indoor areas.
The powerful UVC radiation is completely isolated inside the device ensuring the safety of people nearby and therefore safely allows human presence in the room.
Its innovative design provides fast and effective sterilization of any space.
Recent studies show and that UVC is also effective on SARS-CoV-2 (virus which causes COVID-19), in doses lower than SteriLumen provides.
For the deactivation of the 99.9% of the virus a dose of 6.6 mJ/cm2 is required. UT-225 at the fastest sterilizing rate provides 16.5mJ/cm2 ,and at lowest speed provides 110.5 mJ/cm2 ,enough to deactivate the 99.999% of the virus.

HOW DOES IT WORK? STERILUMEN UT-225 uses a powerful fan to pull in the air and channel it to a series of chambers that contain the high radiation UVC bulbs. The air remains in the chambers long enough for the viruses and other micro-organisms to be neutralized. The clean air is redistributed into the room free of any infectious organisms.

HOW IS IT SO EFFECTIVE?
The effectiveness of the STERILUMEN UT-225 is a combination of the high radiation UVC light, the small space in the chambers and the time that any microorganism stays in the chambers. UVC radiation loses its efficiency geometrically with distance. The small chambers assure us that the microorganisms will pass adjacent to the UVC light and receive enough radiation. Moreover, the geometry of the device is such to cause the infected air to be exposed to the UVC radiation long enough to achieve the neutralization of the microorganisms and viruses
SAFE TO USE
STERILUMEN UT-225 prevents UVC radiation spill completely through an automatic sensor that shuts off the device in case someone opens it while in operation - much in the same way microwave ovens switch off if opened while in use.
WHY TEST THE STERILUMEN UT-225 IN THE LABORATORY?;
Even though the UVC radiation is being used since the 1800’s as a germicide, we wanted to test whether the STERILUMEN UT-225 can neutralize the viruses in the air in a live office. The presence of people in the room causes the air to maintain a microbial load at all times, making it more difficult to clean. The laboratory results have shown that the UT-225 can kill 93.2% of all microbes within the first hour (the tested space was 100sq. meters). This result supplements CDC recommendations for UVGI, which they consider as an effective method in reducing the transmission of the airborne bacterial and viral infections.
WHAT TYPES OF GERMS AND MICROORGANISMS IS IT MOST EFFECTIVE AGAINST?
STERILUMEN UT-225 is very effective in targeting many types of viruses and microorganisms that causes infections and allergies, including algae, yeast, fungus and airborne viruses.
WHY STERILUMEN UT-225 IS BETTER THAN OTHER SOLUTIONS
Α. STERILUMEN is 100% safe to be used while people are present in the room as the UV radiation is hermetically trapped inside the machine. Other devices that can be found in the market use open UVC light that can be harmful to people and should only be used while wearing protective equipment for the skin and the eyes. Moreover, the lamps that STERILUMEN uses come with a filter that prevents the production of Ozone, unlike other devices in the market.
Β. STERILUMEN has been designed in a way that the radiation that hits the air is so strong that it completely neutralizes the microbial load.
ARE THERE OTHER SOLUTIONS IN THE MARKET? WHAT ARE THEIR DISADVANTAGES?
1. Open type UVC devices.. For safety reasons, these devices cannot be used while people are present in the room. The UVC bulbs only sterilize the air that passes next to them (mm) and cannot be effective at a distance.
2. Ceiling mounted UVC luminaires with indirect lighting (towards the ceiling)., These devices need to be placed in high ceiling and away from reflective surfaces in order to avoid being harmful to people. They only sterilize the air in close vicinity. Therefore, the sterilization takes much longer.
3. Closed type UVC devices like STERILUMEN., The devices currently available in the market are either too weak to neutralize the virus or the air remains in the machine for too little making them completely inefficient.
4. UVC devices for HVAC.. The UVC dose that hits the incoming air is not enough for sterilizing the air. Moreover, the installation of such devices inside the A/C ducts, causes pressure drop and reduces the efficiency of the A/C unit.
5. Air Ionisers. They are not very efficient on bacteria and viruses.
UVGI (UltraViolet Germicidal Irradiation) is a is a method of disinfectation that uses short-wavelength ultraviolet UV-C light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. Over the last 40 years, UVGI has been used for disinfecting drinking water, air, wastewater, pharmaceutical products and surfaces against human pathogens. Viruses and bacteria are highly responsive to UV disinfection at appropriate doses. Published studies show that UV-C completely inactivates the other corona viruses (SARS-CoV-1 and MERS-CoV.) Recent studies show and that UVC is also effective on SARS-CoV-2 (virus which causes COVID-19), in doses lower than SteriLumen provides.. There are no known micro-organisms which are resistant to UVC radiation. The UV-C radiation break down the DNA and RNA of bacteria, viruses and spores, making them harmless. Hospitals and governmental buildings have used UV-C technology safely and effectively. UVC lamps are safe when used properly. If exposed to UVC lighting, there is risk of burning skin or superficial tissue damage of eye. It is important that lamps are always shielded and out of sight/touch.
