Your video claims that masks don’t work because they’ll leak vape smoke. However, masks aren’t meant to be airtight, but rather a barrier against droplets (like the kind expelled when you cough or sneeze). Droplets are what primarily carry the virus across long distances.

This says that the virus can be an aerosol and that this is what causes infection after long time periods after a spreader was in the area.

Can someone confirm if vape is an appropriate analog to aerosol virus in our breath? If so, the video is very convincing that masks are ineffective at preventing infection.

Aerosol covid viral particles are much, much smaller than the spaces between the fibers of a cloth mask, or an N95 mask, and anyways, you can see the vape going out the sides.

Yes, they work on droplets. Obviously you didn't watch the whole thing. No, droplets are not the only mode for delivering the virus.

This shows that masks aren't perfect, not that they don't help.

Right. After having Covid in April 2020 I developed what appears to be a hypersensitivity to Covid, where I get an allergic reaction when exposed within about 20-30 minutes. It's not pleasant, but I guess you could say I'm a human detector similar to what dogs have been trained for. I can assert that surgical, N-95, and KN95 are not completely effective in my experiences. P-100 masks however have been basically full proof so far. They have been a goto despite being expensive. They can be covered with cloth If you think they look dorky. Another antictode is that there are a lot of weak viral shedders with little or no symptoms out there. During some of the bad months I've inferred it must be around 1/5 to 1/10 people.
