Visium™ in Healthcare.

Visium™ allows healthcare employees to work with peace of mind.

Visium™ Technology

UVC Sanitization.

Healthcare facility owners must balance the health and well-being of both staff and patients. With growing concerns of HAI (hospital acquired infections) and the constant challenge of staff shortages, indoor health has become a key concern amongst owners. Increases in manual cleaning and upgrades to HVAC and traditional UVC can be costly and come with inherent flaws. 

Lit Thinking’s™ sanitization devices utilize human-safe Far-UVC technology. This can be the ideal solution to sanitize air in high-touch, high-traffic areas in medical and senior care facilities.

Work With

Peace of Mind.

Unhealthy indoor air environments impact everyone. Investing in indoor health is investing in our students, our employees, and our communities. Government, educational institutions, healthcare, businesses, and building owners now recognize the critical importance of indoor air quality. While upgrades to the HVAC systems may help, additional measures, such as adding Far-UVC solutions, may be required to improve our indoor air environment.

Lit Thinking’s™ utilization of human-safe Far-UVC is the perfect investment. Research shows dramatic improvements in the sanitization of spaces with insufficient ventilation and high traffic areas when Far-UVC is deployed.

The Importance Of

Air Changes.

Air changes per hour (or ACH) is how many times the volume of air in a room is replaced through ventilation per hour. This is a common way to determine how healthy a room is or how clean the air is within an enclosed space. Homes typically have 1-2 ACH, commercial offices 2-3 ACH, schools 5-6 ACH, and hospitals requiring 6-20 ACH. 

American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) recently updated the Standard 62.1 (Ventilation for Acceptable Indoor Air Quality) in 2022, which focuses on ventilation rates in terms of cubic feet per minute (CFM) per person rather than Air Changes per Hour (ACH). 

Both the CDC and EPA support these enhanced recommendations from ASHRAE, recognizing the necessity for improved ventilation strategies to foster safer and healthier indoor environments, surpassing what was previously deemed as merely acceptable.


Modern Cleaning Methods without Far-UVC

Effective use of air changes removes particles from the air and replaces it with clean air so that only a fraction remains after an hour. For example, if a person sneezes in a room that uses 5 ACH before leaving and shutting the door behind them, in 5 minutes 66% of their sneeze will remain; in 30 minutes 8.2% of their sneeze will remain; in an hour 0.66% of their sneeze will remain.

In areas of insufficient ventilation, not enough air is changed to effectively remove airborne contaminants and pathogens. Additionally, in high traffic areas, infectious particles are constantly introduced into the air. In these instances, adding filtration or UV lights increases air cleaning rates. Because these methods do not necessarily change the flow of air into the room, the cleaning efficiency of these methods are often quantified using equivalent air changes per hour (eACH). 

The addition of Lit Thinking’s™ Far-UVC sanitization solution provides 184 eACH, cleaning even the most populated rooms or least ventilated rooms.

The addition of a Far-UVC sanitization solution can provide up to 184 eACH in a full-size room. (Eadie et al, 2022)

A New Way to Clean.

Clean Air at Light Speed.

Visium™ uses 222nm Far-UVC technology to sanitize your buildings continuously while the Lit Thinking™ app provides you with real-time updates on the sanitization and IAQ status of individual rooms where Visium™ technology is deployed.

Continuously Sanitizing up to 99.9% of Pathogens.

Fully automated, safe, and simple, Visium™ provides constant air and surface sanitization where ever it is deployed.
