Excelitas Kepri™ UV LED Upper-Air Disinfection System
The Excelitas LED-based Kepri™ UVC Upper-Air Disinfection System provides safe, effective, real-time disinfection of upper-level room air regardless of room occupancy. Kepri’s potent UVC energy is effective against a wide range of pathogens including bacteria, mold and viruses such as those that cause COVID-19. With a truly unique design, our Kepri UVC Upper-Air Disinfection System allows for safe and effective room air disinfection without emitting any harmful or environmentally unfriendly ozone gas.
The Upper-Air Concept
As pathogens pass through the active UVC disinfection zone, the UVC light damages the pathogens’ DNA/RNA, preventing its ability to replicate and effectively inactivating its ability to infect and spread. This continuous disinfection offers higher levels of effectiveness when compared to other traditional UV lamp-based air germicidal treatments at lower power.
The compact Kepri UVC Upper Air-Disinfection System is easy to install in a wide variety of spaces. Featuring low noise operation and a dust free optical chamber, this low-profile design minimizes maintenance requirements and ensures maximum UVC emission.
As safety is critical in UVC disinfection, Excelitas sets the industry standard with a three-tiered sensor monitoring system to ensure safe operation, even in fully occupied rooms:
- Tilt Sensor: a safety feature to ensure no harmful UVC energy is emitted into the lower part of the room.
- Presence Sensor: detects anyone in the UVC central emission field (i.e. changing a lightbulb on a ladder) and immediately turns off the UVC emission until the emission field is clear.
- Motion-Activated Occupancy Sensor and Switch: detects movement in the room and allows the user to select their individual operating preference using a three position selectable switch.
Excelitas meets a stringent UL-8802 standard which limits the amount of UVC energy into the lower part of the room, assuring safe operation.
Effective Pathogen Elimination
Third-party testing shows that Kepri reduces the airborne viral load by 99% in as little as 20 minutes. No matter if it is bacteria, mold, or virus, Kepri effectively reduces airborne pathogens. Click here to view our Efficacy Test Report.
1.Effective air exchanges per hour (ACH) for a room with a 10ft (3.0m) ceiling.
2.Values are extrapolated from Intertek test data dated Dec 17, 2021- available on our website. Original single point test measured a 99.9% reduction of Coliphage φX174 (typical single stranded virus) in 20 minutes. Effective air exchanges for other pathogens will differ.
3.The times given assume perfect air mixing within the space (i.e. mixing factor = 1). Disinfection rates are dependent on air mixing. The following effective air exchange (ACH) data should only be used as a best-case guideline.

Interested in learning more on the effectiveness of upper room disinfection for cleaning our indoor air? Read this latest article:
Dr. Edward Nardell, a Professor in the Departments of Environmental Health and Immunology and Infectious Diseases from Harvard Medical School, has written a detailed article on the best ways to clean indoor properly to avoid spreading viruses. As he states in the article, viruses like SARS-CoV-2 (COVID-19) and their variants will certainly cause future problems and pandemics over time. As a society, we need to plan scientifically how to reduce virus spread when masks are not as common. Dr. Nardell states, there are “three established and proven air disinfection technologies: mechanical ventilation, upper room GUV, and portable room air cleaners. Of these, upper room UV is the most cost-effective and is demonstrably safe and readily available to deploy today to reduce COVID-19 and other respiratory virus transmission."
