N95 seems to be a standard. Furnace filters and vaccum cleaner
bags claim to adhere to various standards. That study done with
5 subjects seems pretty hokey and un scientific.
With so much unknown about this virus there are only assumptions
we have to deal with currently.
1 It spreads fast.
2 It kills quickly.
3 Treatment seems to be attacking the symptoms and hoping for the best.
4 Most will survive.
5 Aquired immunity is uncertain.
6 The particle size has been estimated at 1 to 3 microns.
7 Whether the virus needs a live host has been debated.
8 Far to many people are ignoring all precautions.
9 Dr. Fretwells assesments may be correct but I'm not betting my
life on it.
We wear masks and gloves as appropriate
We wash hands a lot
We try not to touch our faces
We social distance and monitor people nearby for behavior
Anything we purchase gets disinfected with Lysol in the car and or
in the garage before bringing into the
house.
In general, we follow the latest advice from the heavy hitters.
