Should I Wear a Mask?


"As soon as your body notices an infection, it immediately tries to grow a response while the virus tries to grow itself. From then on, it is a race to see which can grow biggest fastest. And the virus gets a big advantage in this race if its initial dose of infecting virus is larger. This effect is widely known and acknowledged by experts, and it is one of the main rationales given for wearing masks, gloves etc. That’s not just to cut the chance of an infection, but also to cut the initial dose."

Written in 2008 and not specifically about COVID-19. From the abstract: "Any type of general mask use is likely to decrease viral exposure and infection risk on a population level, in spite of imperfect fit and imperfect adherence, personal respirators providing most protection."


Discusses a study which household materials protect best against bacterial and viral particles. Though some materials protect much better than others, even the least effective materials captured 50% or more virus particles.

Smoke/Gas Mask Respirator by mussy (3D Printed)- I thought this mask’s filters were interesting since they were feasible to make with scavenged materials. You need cotton pads and activated charcoal (or perhaps cotton pads soaked in salt instead) which could be made, but more easily sourced. Altogether, though, I’m not sure how safe and effective it would be if tested. With activated charcoal though, it could be better than the previous three.
