coronavirus vs air filter

Post by brandy » Sun Mar 08, 2020 10:57 am

The manufacturer of my air filter says it “Removes 99.97% of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns.”
Wikipedia article authors say “The genome size of coronaviruses ranges from approximately 27 to 34 kilobases, the largest among known RNA viruses”.

Will my air filter capture those viruses?

It should work if you can just get everybody to breathe directly into the filter...

Before this gets locked I'll say the real risk is direct contact. Someone with the virus touches a doorknob, then you touch it then rub your eyes. Or they sneeze on you. You're not getting it sitting in your house with or without a filter.

If the virus is in your home, you're likely infected irrespective of if your filter does remove the airborne contaminant.

There IS that. I planned to get a new filter for it in the fall--Oct or Nov, but thought if it would help, I'd get it now, instead.
From the link above: “The filter itself is .3 microns and the virus itself is roughly .1 microns.”

VS Removes 99.97% of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns. So...

My understanding is that unless someone coughs on you, the spread is by physical contact, with the person, or with something that they coughed on. Sadly, an air filter isn’t much help for that.

I wish it were, we have a contractor and his guys crawling all over our house right now. We’ve resorted to washing our hands like we’re obsessive compulsive, and wiping everything down with Clorox wipes the second they leave for the day. We’re running our air filter full time, but that’s mostly about the dust they’re kicking up.
Yes, I’m really that pedantic.

Thanks for the reminder. Yes, that's what I've heard/read, too. I just forgot. :oops:
I self isolate, due to multiple chemical sensitivity/environmental illness, and now severe COPD, I should be /probably will be okay.
