Introducing the Safe Air Score: Enhancing Indoor Air Quality and Safety

In today’s world, ensuring the safety and cleanliness of indoor environments has never been more critical. With the emergence of new threats to public health, such as airborne pathogens, maintaining optimal indoor air quality is paramount. That’s why Lit Thinking is proud to introduce the Safe Air Score – a revolutionary tool designed to provide real-time insights into the sanitization level of your environment, ensuring not just healthy, but also safe indoor air.

At the heart of the Safe Air Score is Lit Thinking’s cutting-edge Visium technology, which utilizes filtered far-UVC light to sanitize the air in occupied spaces. By continuously monitoring room occupancy and analyzing indoor air quality, the Safe Air Score offers a comprehensive assessment of the sanitization level in any given area.

The development of the Safe Air Score algorithm draws upon research by Eadie et al., which establishes a methodology based on the assumption of a constant influx of pathogens indicative of a sick individual’s presence. This innovative approach allows for the estimation of a steady state of pathogen reduction, effectively indicating the potential effectiveness of Visium devices in reducing the pathogen load in the air.

Several critical factors influence the Safe Air Score, including the size of the room, the existing ventilation, the number of Visium devices installed, and whether the room is currently occupied. In rooms recently vacated, the absence of an assumed continuous pathogen source enables the Safe Air Score to rise, reflecting the cumulative sanitization efforts of both the far-UVC devices and the HVAC system. This upward trend in the score signifies the room’s return to optimal air sanitization levels.

Moreover, the Safe Air Score contributes to improved energy efficiency and bulb life in the ‘Occupancy’ operating mode. Once the score reaches 99, indicating maximum sanitization, the Visium devices automatically shut off to conserve lamp life, reactivating only when occupancy is detected. This intelligent feature not only enhances energy conservation but also prolongs the longevity of the devices, ensuring sustained effectiveness over time.

The Safe Air Score represents a significant advancement in indoor air quality monitoring and management. By providing real-time insights, optimizing energy usage, and offering flexible operating modes, the Safe Air Score ensures that indoor environments remain safe, clean, and conducive to health and well-being. With Lit Thinking’s Visium technology and the Safe Air Score, you can breathe easy knowing that your indoor air is in safe hands.

*An important reminder – even perfect, pathogen-free environments do not eliminate the risk of infection from close-contact human-to-human pathogen transmission. We always recommend sensible precautions, including frequent hand washing, maintaining appropriate distances, and, if the situation requires, the use of facemasks or suitable personal protective equipment.
