Below is a detailed contrast between the two approaches.

There is a growing demand for engineers to evaluate and design ventilation and filtration systems to improve indoor air quality as part of the reopening phase of the COVID-19 pandemic. School districts are currently developing plans for teachers and students to safely return to classrooms, and they will use the summer to upgrade facilities and to study the most impactful health and safety measures. A May 2021 report by the Johns Hopkins Center for Health Security has many useful answers.

By Rick Wood, Jennifer Marsh and Craig Barbee October 29, 2021 To test the feasibility and effectiveness of a duct-mounted ultraviolet system, Smith Seckman Reid commissioned a test where an aerosolized water solution of biosafety level 1 Staphylococcus epidermis bacterium was introduced into the ductwork airstream and evaporated into the airstream before passing each device, then samples were collected and incubated for seven to 10 days.
