The fact that Covid is dangerous is at odds with how most people live. So they pretend it’s not, because it’s too hard to do anything about. It would be more convenient for it to not be true. But it is true. So what can the average person do to mitigate in a realistic way? 1/

Again, let me be clear. I wish people masked all the time. But if you’re currently a person who masks NONE of the time, it’s better for you to mask at least sometimes. 10/

Thanks for asking! We now have a little zine that answers those questions!

I know it looks a little silly, but for those with hearing disabilities these Savewo Smile mask could be game changers. Hard to tell in pic, but I just had this in the freezer, breathing on it and no fogging. This get the mask nerd nod of approval. Breathability is still good!

N95? KN95? KF94? The best is whichever fits you. I have high cheekbones & most N95s leak at my upper face. All Kf94s & most KN95s fit me perfectly, though, & I tie knots in ear loops to tighten just right. @masknerd has a great video: Fit, Fit, Fit!!!

N95 or KN95 masks offer best protection, real-world study shows
"In a real-world study of face masks conducted before the omicron surge, people who reported wearing N95 or KN95 respirators in public indoor spaces were 83% less likely to test positive for SARS-CoV-2 than people who never wore a mask."

Today's a great day to remember that, if you need a doctor's note to wear a mask at work:

  1. The CDC has helpfully provided a list of high risk conditions which can necessitate masking in order to protect yourself or a loved one, and...

  2. Many of them are very, very common.

I've been trying to explain this for two years now. N95s were designed primarily for male caucasian faces. KN95 and KF94 standards came about not because we wanted a knockoff mask standard, but because Asian faces could not pass fit tests with N95 masks.

Faces come in different shapes. (For example, most well-rated N95s leak at my nose and don't fit my cheekbones. Oft-maligned ear loop Kf94s fit me perfectly, and pass fit tests.) How to fit test masks at home:

Thread So all this BS about there being no RCTs proving mask effectiveness are lies.

A) A proper RCT is impossible, and B) an RCT that tested "being forced to wear a respirator, but only at work" vs "up to you" showed respirators meaningfully reduced infection.
