I don't think this needs to be absolutes. Properly fitted N95 > N95 > Surgical > none.

If sick people work an average N95/KN95 mask off of Amazon (which is the 'good' I was referring to), it'd help. It's not perfect, and you can do better, and you can do worse. But it's a reasonable intersection of "easy to do" and "effective".

Other comments disagree with you. An N95 that isn’t absolutely perfect would seem to be worse than a piece of cloth, if whatever arbitrary study financed by some unknown group with unknown incentives referenced by said commenter is to be believed. Which it probably isn’t. But it’s as good as any of the other “research” of such heavily politicized topics.
