interesting,

somebody who works for Home Depot does a post on HEPA filters, (which work for Covid and can be purchased from HD) and they are an expert on pharmaceutical and medical laminar air systems.

which are controlled by state licensing agencies, each of which has different air flow rates and filter requirements for every medical user,

and each user must keep logs showing replacement and hrs. of use. which is audited by inspectors.

and are different for sterile preps. vs. oncological preps. vs compounding


And then a disagreement as to the mechanism face masks perform their function, when the only real question is if they work at all. (don't confuse persons per sq. foot densities with mask effectiveness)

and then a diversion into aerosols, from someone who doesn't know the differences in physics between colloids and aerosols if they were smacked in the head with a lugey

person walks into hospital with 3 stents, 100 lbs overweight Covid positive dies and someone things its caused by Covid (they don't know or care about the difference between causality and correlation)

and if you haven't heard the CDC has quietly removed the 10 day quarantine .


Most people don't have what it takes to get old
