A surgical mask only traps 44% of airborne covid 19. A cloth mask only catches 4%. A bandana? 0.0% It's nothing more than decoration. I spent 35 years keeping people safe from hazardous materials, got a lot of training. Want to eliminate 100%? Charcoal filters or a Scott Pack- and then only if they are properly fitted. Dontcha love those people protecting you protecting me who only cover their mouths? Covid 19 leaves a bitter aftertaste. Every single Doctor like Fauci? Who said no one needs to wear a mask so medical people can wear them, then said everyone should wear a mask, then said the N-95 that have an exhaust port spread the virus then (golly what will he contradict himself on next). Look up cross contamination. You touch it, you contaminate it, wear it once and trow it away and it still doesn't catch the micron sized coronavirus. Feeling the burn yet duped sock puppet?
