Air Sanitization Performance

Pathogen: Aerosolized SARS-CoV-2 The inactivation constant for SARS-CoV-2 in air was taken directly from Welch et al (2022) “Inactivation Rates for Airborne Human Coronavirus by Low Doses of 222 nm Far-UVC Radiation “. Viruses. https://pubmed.ncbi.nlm.nih.gov/35458414/

eACH Far-UVC: eACH Equivalent Air Changes per Hour (eACH) - Pathogen inactivation rate equivalent to the number of air changes in a room per hour.


eCADR: cfm Equivalent Clean Air Delivery Rate (eCADR) - Pathogen inactivation rate equivalent to providing clean air in cubic feet per minute (CFM) in a room.

50% Inactivation Time: minutes

90% Inactivation Time: minutes

The values shown are based on the assumptions of uniform Far-UVC distribution and well-mixed air.

The values shown by this calculator are estimates of the potential eACH and pathogen inactivation performance from installing Visium Far-UV devices in the specified space. These estimates are based on various studies, included the reference below, and the inputs provided. Actual performance may differ due to factors such as specific installation parameters, operating conditions, HVAC system performance, specific site architecture, furnishings, materials used, and changes in layout.
