There are better ways to prevent infections

Reduce infections in occupied spaces

What is Far UV-C?

Simple yet intuitive

Discover the power of i222 – a proven solution for significantly reducing harmful air and surface pathogens.

With its safe operation in busy shared spaces such as hospitals, classrooms, offices, restaurants, and gyms, i222 can help lower the risk of infection in these areas, leading to fewer sick days and increased productivity.

Whether wall or ceiling-mounted, i222 can cover up to 300 sq ft. The built-in Ushio Care222 filtered lamp module ensures that only safe wavelengths of light are emitted into the air and onto surfaces.

Thanks to its motion sensors and LIDAR, i222 can accurately measure the distance to people and adjust UV-C dosage based on room occupancy. Additionally, i222 operates within ACGIH Threshold Limit Values (TLV), ensuring safe levels of UV light exposure at all times.

Safety built-in

The i222 lamp is available in two different lamp angle configurations – 60° and 100° – the 60° offers more focused Far UV-C light distribution, and 100° creates a broader footprint and a larger coverage area.

i222 eliminates human exposure to harmful wavelengths through Ushio’s Care222™ built-in patented optical band-pass filter. This means i222 is safer than other Far UV-C units which use krypton-chloride excimer lamps.

i222 carries a two-year/17,500-hour warranty and has zero ongoing maintenance costs. It can be hard-wired or supplied with a standard U.S plug fitting and consumes just 17 watts of electricity – 10 times less than many air purifiers – meaning lower lifecycle costs.  

2 year/17,500 hour warranty

Bespoke installation and design

Each i222 installation is designed from building floorplans to ensure that every open space and surface is best protected with lamps deployed in the most critical parts of a room.

i222 lamps can be programmed to be active during busy periods or disabled when buildings are vacant, such as schools during the holidays or restaurants and bars overnight.

i222 allows users to adjust settings for each lamp and warns when lights are nearing the end of their lifecycle.

Fast pathogen reduction

i222 incapacitates over 90% of upper aerosolised SARS-CoV-2 in 29 seconds; surfaces are treated to the same reduction level in just a few minutes.

222nm Far UV-C light has been proven in studies worldwide to reduce surface and air infection risk in seconds and be safe for human exposure in doses up to 500mJ/cm2. 

i222 is not just a solution to the pandemic. It will also help eradicate bacteria such as MRSA and C-Diff, mold and yeast and help incapacitate Influenza and the Common Cold.

What is Far UV-C?

UV light is broadly classed into three types: UV-A, UV-B and UV-C. Since it has the highest energy, UV-C is the most dangerous ultraviolet light to humans.

UV-C, known as “germicidal” UV, neutralise pathogens such as viruses by attacking their DNA and preventing them from replicating. However, 254nm UV-C can’t be used in occupied spaces.

Far-UVC has a shorter wavelength of 222nm and higher energy, which can effectively neutralise viruses. Dead layers of cells absorb their wavelength and are harmless to humans.

Why is 222nm light safe?

Did you know that, unlike traditional 254nm UVC light, which can potentially cause cataracts and lead to blurry vision, 222nm Far UVC light is much safer for the eyes as it does not penetrate the cornea, which is the eye’s outer layer?

It is important to note that UV light with a wavelength of 254 nm can penetrate deep into the skin and potentially lead to skin cancer. On the other hand, Far UVC light with a wavelength of 222nm does not penetrate the epidermis and is considered safe for exposure.
