Yesterday, I posted the video of the hot girl with the colorful dust on her.
Island was kind enough to take a screen shot of a "concern" of regular mask, including surgical mask- ill fitting margins which let in unfiltered air from the sides/bottom. The mask I use has a lower adjustable strap, so it's good, but many others dont have it.
At work today, I wondered "how hard would it be to fix?" I'd seen patient's solutions.
Took a cheapo surgical mask, removed the aluminium nose strap, cut an access into another mask on the lower edge, and fed in a lower strap.
Took 45 seconds.
Here's the aluminum strip taken out of el cheapo mask-
Here's a slit in another mask on the lower edge to accept the aluminum strip-
Here is an el cheapo mask which fits better than numerous kn95's I've used- I think- it fits as well as n95 for normal tidal volume breathing and talking.
45 seconds.
