How to Achieve 99% Airborne Virus Reduction with Far-UVC Technology

In the blog post, we will share some thoughts on how to Eliminate Airborne Viruses in Occupied Rooms Using Far-UVC Technology

A recent study published in Scientific Reports shows the real-world effectiveness of Far-UVC light, bridging the gap between laboratory studies and practical applications. This research demonstrates how Far-UVC technology can almost eliminate airborne viruses in occupied rooms.

Significant Reduction in Airborne Viruses

The study by Buonanno et al. at Columbia University aimed to measure the reduction of airborne viruses using Far-UVC light at 222 nm installed in a ceiling within an occupied work environment. The findings were impressive: Far-UVC light reduced airborne infectious viruses by more than 99%. This substantial reduction aligns with previous studies conducted in room-sized bioaerosol chambers, suggesting that Far-UVC light may be even more effective in larger, real-world settings.

Far-UVC Effective Against Influenza and Coronavirus

The researchers used a conservative surrogate virus harder to inactivate with Far-UVC than more dangerous airborne viruses. This choice highlights the effectiveness of Far-UVC in safeguarding people from airborne threats such as influenza and coronavirus.

Superior Air Purification Compared to Traditional Methods

The study calculated the equivalent air changes per hour (eACH) to compare Far-UVC to conventional ventilation systems. The result was 1480 eACH, showing that Far-UVC offers significantly better protection against airborne viruses than any ventilation system could achieve.

Far-UVC is absorbed by proteins in the outermost skin and eyes, making it safe for human exposure. Critics often claim that Far-UVC light sources have lower power output than conventional UVC lamps. However, scientific studies demonstrate that Far-UVC can combine both human safety and germicidal efficacy.

The Impact of Air Hygiene

Reducing airborne viruses in occupied spaces has significant public health benefits. Far-UVC technology can be used in high-traffic indoor areas like hospitals, offices, and public transportation systems. Far-UVC technology can help prevent disease spread by continuously neutralizing airborne pathogens, complementing traditional methods like vaccination and mechanical cleaning. This continuous disinfection offers a consistent and reliable layer of protection, ensuring that air quality remains high throughout the day, regardless of foot traffic or activity levels.

Implementing Far-UVC technology in these settings can drastically reduce the transmission of airborne diseases, protecting both the public and the workforce. The implications for public health are vast; this technology can help control the spread of common illnesses like the flu and more severe threats like coronaviruses. Far-UVC can play a critical role in mitigating the impact of future epidemics or pandemics by providing an effective, ongoing solution for air hygiene. Additionally, improving air quality in these environments can enhance overall well-being, reduce absenteeism due to illness, and create safer, healthier public spaces.
