There has been a lot of confusion and debate over whether or not masks protect people from catching coronavirus.
People against the use of masks will point to a cloth mask and claim that it doesn’t actually filter out things as small as viral particles, therefore they’re useless.
First of all, those types of masks are meant to stop otherwise healthy people from passing the virus to others with no symptoms themselves. As the cloth contains a lot of the exhaled respiratory droplets that are filled with viral particles, they stop a considerable amount from passing through the fabric. Furthermore, there masks that work with a filtration efficiency of a HEPA filter. They don’t realize that many of us are ordering N-95s off the internet to protect ourselves from the ones that won’t wear any kind of mask. These masks are phenomenal at preventing the spread of the virus, it’s just that many don’t know what they are or where to buy them. I admit, I’m privileged to have a decent job where I can afford to order these premium masks off the internet. I’ve gone as far as buying special allergen filters for my central HVAC system that match the filtration abilities of HEPAs. They block particles as small as viral microbes from passing through the filter medium. If you have someone at your house who is asymptomatic, any viral shedding that gets into your indoor air will get removed whenever the air conditioner is running. Ideally, businesses and homeowners everywhere would be using filters like these to constantly clean their indoor air and prevent viral transmission.
