Understanding COVID 19

[Old Mud]

As do some septic systems. These lights have high UV output, they're not the "Black Lights" we used to pull out and look at posters in our rooms in the early 70s while "inhaling". The ones on filters are there to kill bacteria and viruses that are trapped on the filter. Most HEPA filters remove 99.7% of particles 300 nm and larger, which covers bacteria and some viruses that can range from 250 - 500 nm.

The SARs corona virus was 19 nm in size so that one wouldn't be trapped in a "normal" HEPA filter. Right now I can't get through all the news on COVID-19 to get to actual size, but I'm guessing it's going to be close to the "old" SARS virus since it's a member of the same family

I heard a dr. on tv a few days ago say that "in the neighborhood of 20,000 would fit on a pin head."

They would go through a Hepa filter like gas through a funnel and eggs through a hen. Slicker than scum on a lousiana swamp.

I'm not a big fan of hearing about type A. I'm not only 80 and have a Bronchitis problem but i am type A+ ugh. Dam i might as well go out there and start licking shopping cart handles.

I think any virus that sees you immediately runs like hell!!!! They don't want to be associated with such an ornery and tough old codger!!
