The ≤ 1 μm fine aerosols from talking do not “fall” down to the ground …. They weigh less than 100 femtograms … so … They float & swirl & circulate for at least 4 – 5 hours … and they remain hazardous~infectious with 90% viral loads beyond 3 hours….
0.0000000000001 g = 100 femtograms… => an aerosol so fine, that it barely evaporates, even after hours of swirling around inside a room
These fine aerosols are so small & so-easily sucked deep into our throat & lungs by our normal breathing , that if you have any leaks or gaps around your mask (5% leakage for N95 masks and 40% leakage for cheap flat masks … and 70% leakage for home-made masks) , then these tiniest, invisible, most-infectious, highest-risk aerosols are swept around your mask … through your cheap mask … and DEEP into your throat & lungs…
Consider how we panic over just one 1 cough …. while a cough has just 60 of these fine aerosols…
While 5 min of normal-volume talking by a person without a mask … produces 104 coughs worth of these most infectious aerosols… 1500 Fine Aerosol Particulates for just 5 min of talking…
Our vibrating vocal cords are superb aerosol generators … and the Asymptomatic Spreader’s THROAT is putting-out peak amounts of virus during the 2 days before symptoms appear… dumping that throat virus-loaded mucous right onto our vocal cord fine-aerosol generators.
Note that these nastiest aerosols swirl & spread like mist … fog … slowly circulating out to 30 ft from the talker … CONTAMINATING a room for the next 4 – 5 hours…
Did anybody reading this notice that Social Distancing is DOES NOT WORK … not at all
… because these worst aerosols travel-swirl 20 – 30 feet from the talker … and the persist in a room … filling the room with contaminated infectious droplets …. circulating highly infectious for 4 – 5 hours … AND MOST MASKS DO NOT PROTECT AGAINST THEM…
Most masks leak too much … leaking in 4000 of the nastiest fine aerosols per 10,000 aerosols from an asymptomatic spreader – loud talker … who WAS IN THE ROOM 3 HOURS AGO…
Now, do we understand why compulsive hand washing, ~bleach spraying everything~ and “Social Distancing” are not working … They’re the wrong solution – that don’t work for this Coronavirus problem …. Instead,
Get a good mask!
The “95” in the N95 masks … means it leaks 500 of the worst nasty aerosols out of just 10,000 particulates …. INSTEAD A GOOD mask … made of surgical barrier cloth … like an N100 mask only leaks in 3 fine aerosols per 10,000 … and yes, our immune systems & respiratory mucous membranes EASILY HANDLE 3 fine aerosols…
So on a relative scale, your N95 mask is leaking 500 contaminated most-infectious aerosols, out of 10,000 ( 8 COVID-coughs worth ) … while a good surgical barrier cloth mask leaks only 3 particulates…
To protect your family & friends …
Open the attached diagrams … read them carefully… and consider ordering some masks

and yes… I did 3 yrs of aerosol science work … generating & wrangling & measuring these exact kinds of aerosol droplets – particulates… 😉
NEXT … Spend some time with the crude-but fun diagrams below … comparing the #’s of droplets, … how long they last (3 – 5 hrs – virulent) … How they threaten all our workers who work inside & medical personnel … to see why the CDC’s efforts have failed.

Talking Aloud for 5 minutes Creates Far Far More of the Highest Risk Aerosols:Soft talking for just 5 minutes => 750 fine aerosol droplets
…. equals => 12 mouth-uncovered coughsNormal talking for just 5 min. => 1500 fine aerosol droplets
… equals =>25 mouth-uncovered coughs
LOUD talking for 5 min. => 6,000 fine aerosol droplets
…equals => 100 uncovered coughs
The Super-Spreader people >= spew 15,000 fine aerosols
… equal to 250 uncovered-mouth coughs … in just 5 min of talking.
Those 750 or 1500 or 6000 fine aerosol droplets float around inside rooms … for over 3 hours … remaining highly infectious the whole 3 hrs.
