While hospitals and healthcare facilities may have HVAC systems with components like high-efficiency filters and UVGI that can effectively eliminate viruses, simple steps may help prevent or reduce infections in the workplace and include: While human transmission of the SARS-CoV-2 virus is new, some of the science around ventilation and infection control is decades old. Learn the best way to handle an employee’s refusal to wear a mask and your company’s best course of action in response. Filtration is specific to each select group of containments. The Minimum Efficiency Reporting Value (MERV) must be stated with the air velocity at which the filter was tested.
