UVC LED Air Disinfection Devices

With an increased concern on the transmission of airborne viruses, Olympia’s LED UVC air disinfection devices are here to reduce risk and bring peace of mind. For quite some time people have relied on ultraviolet radiation to inactivate viruses, and now with the spread of COVID-19, this kind of virus protection is especially important.

What Is Airborne Transmission?

When people infected with viruses breathe, talk or sneeze they expel droplets that contain that virus. This happens with common colds, flu, and COVID-19. These are also called “aerosols.” It’s been discovered that COVID-19 can also travel in airborne particles, which are likely to be more persistent. They, along with smaller droplets, can travel distances of more than six feet and remain in the air for hours.

What Combats Airborne Virus Transmission?

By now everyone knows about the CDC recommendations to combat the spread of COVID-19. They include distances of at least six feet, masks when indoors with strangers, refraining from large gatherings, handwashing, and surface disinfection. Another measure is UVC air disinfection, especially in air purification and ventilation systems. Recent research shows that an air disinfection system with shortwave UVC germicidal irradiation can inactivate the COVID-19 virus. Also, an EPA study showed that ultraviolet germicidal irradiation (UVGI) combats the spread of airborne diseases.

How Do Disinfection Devices Help?

The ultraviolet spectrum consists of four wavelength groupings: UVA, UVB, UVC, and UV Vacuum. The UVC band is from 200 to 280 nm (nanometers), and that’s the range where UV light is most effective against viruses. Electromagnetic radiation in these wavelengths can keep microorganisms from reproducing by inducing photochemical changes in their nucleic acids.

Lamps that emit this radiation are called UVC lamps or germicidal lamps. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends that UVC emitting devices be installed in air handling units.

What Disinfection Devices Does Olympia Offer?

Olympia offers both standing lamps and devices that mount on a wall or ceiling. Mounted devices include:

– The UVC Air Purifier Lay-in Troffer is a ceiling device with a low profile suitable for standard dropped ceilings. There are adjustable power and dimmer, and you can turn the light off while keeping the UVC LED active.

– The UVC Air Purifier Wall Unit hangs on the wall typically at a height of about seven feet. It adds a 405 nm light for bacterial decontamination.

Safe and Effective

A UVC LED air purifier, such as these UVC air purification devices, creates an inhospitable environment for viruses and bacteria. Air is circulated through these fixtures, and invisible UV light destroys germs, viruses, bacteria, mold, and other pathogens. They operate at an optimal germicidal wavelength of 265 nm and irradiate at 1,500 microwatts/cm2. They protect people and their pets from direct radiation exposure. The LED source is hidden to eliminate the possibility of eye damage. Third-party testing has confirmed these product claims.

Olympia also provides free-standing germicidal LED disinfection lamps suitable for enclosed fixtures. The lamps have additional UVA light to fight bacteria as well as UVC for viruses. The lamps provide both air and surface disinfection.


– Airborne transmission of viruses has always been a concern, and it’s a bigger one in the era of COVID-19.

– Along with hygiene and social distancing practices, another recommended tool to combat airborne virus transmission is the use of germicidal UVC lighting.

– Olympia Lighting offers UVC LED germicidal devices that meet recommended irradiation levels while maintaining safety for humans and animals.
