ALT Q6. What are Corsi-Rosenthal boxes? There have been reports of people constructing Corsi-Rosenthal boxes in an effort to remove SARS-CoV- 2 virus sized particles and improve indoor air quality.24 Corsi-Rosenthal boxes are do-it-yourself (DIY) air cleaners that have purported benefits of being a low cost option with estimated performance ratings similar to commercially available portable air cleaners. The DIY Corsi-Rosenthal boxes (using MERV 13 filters) have been reported in non-peer-reviewed reports to achieve similar CADR estimates to commercial HEPA portable air cleaners.25,26 Some DIY air cleaners were able to achieve similar CADR estimates due to the greater air flow across the MERV 13 filters relative to the air flow of the portable HEPA unit used for comparison.26 Rosenthal states that filter efficiency (e.g., HEPA versus MERV 13) is only one component to determining air cleaner effectiveness – rather, it is a combination of filter efficiency, filter fit and air flow.26 The US E
