➡️ The best mask is an N95, but all masks work
➡️ Double masking or overmasking
➡️ FAQs are:
❓ Does it make a difference?
❓ Which mask should go on top, the cloth mask or the medical mask?
❓ What about two cloth masks?
❓ Or two medical masks?

Meta-analysis:
➡ Physical interventions to interrupt or reduce the spread of respiratory viruses
https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD006207.pub6/full
> The pooled results of RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks. There were no clear differences between the use of medical/surgical masks compared with N95/P2 respirators in healthcare workers when used in routine care to reduce respiratory viral infection.
Research study:
➡ Respiratory Performance Offered by N95 Respirators and Surgical Masks: Human Subject Evaluation with NaCl Aerosol Representing Bacterial and Viral Particle Size Range
https://academic.oup.com/annweh/article/52/3/177/312528?login=false
>Most of the tested N95 respirators and surgical masks in this study were observed to perform at their worst against particles approximately between 0.04 and 0.2 μm, which includes the sizes of coronavirus and influenza virus.
➡ The Foegen effect
A mechanism by which facemasks contribute to the COVID-19 case fatality rate
> This study revealed that wearing facemasks might impose a great risk on individuals, which would not be mitigated by a reduction in the infection rate. The use of facemasks, therefore, might be unfit, if not contraindicated, as an epidemiologic intervention against COVID-19.

➡ Do We Need Mask Mandates?
The science suggests that more states should consider rescinding them.
