I want to say at the start that I know there are some people who cannot wear masks or it is very hard for them. This is by no means about you. So our governor ( Texas) made it a requirement the most everyone had to wear masks in public. I was checking out Facebook and one of my friends posted something about this. Well I started reading the comments ( you would think I would know better than by now but ... nooo.. ) anyway there was the typical comments about liberty being taken away, I wanted to ask .so is it ok if the person making your hamburger doesn't wash his hands because that is his right?, but I was good. Anyway what I came here to ask is some people said the did not work they filtered 1.33% of particles. I know they are not perfect but does anyone have more info on how good they really are?
