I want to see what the science community comes up with.

I was thinking motorcycle helmet with filtered air supply to keep a positive pressure inside like a space helmet.
Air pump, I come up with an idea yet. Ideas welcome.
"Wear an N95 respirator mask, which filters 95 percent of particles > 0.3 microns in diameter."
The typical filtration size of a coffee filter is approximately 20 microns.
High-efficiency particulate arrestance (HEPA) filters: These are the true high end of filtration and are able to filter out 0.3 micron particles.
HEPA filters drastically restrict airflow and should only be matched to a compatible system.

Just stop with any personal hygiene. That will keep other people away, eliminating exposure.

RZ masks are nice, I have their neoprene one. They claim "RZ Mask filters 99.9% of all particulates to a size of 0.1 micron".
I'd been meaning to post about the mask here, here is an excerpt from their FAQ:

Benzene is the only thing I know enough to care about, when dealing with mineral spirits products outside a fume hood (e.g. paint, leukemia runs in my
family). I don't know about many of these others but I thought it may interest someone here.
I'm not sure how a mask would be able to filter out viruses though. I think helmet based ventilation would be the way to go. I guess you could DIY one
like this, by vacuum thermoforming. Or just buy a full face scuba mask and such. Then compress your own air supply away from civilization and carry a tank? Then
again I expect a group somewhere will find a way to vaccinate against the virus.

Get an air system filter (MERV 15 or 16 is equal to N95 or better). Use some Tyvek (USPS mailers priority or express mail envelopes if you don't want
to buy rolls) and cut out 2 sides of a mask and glue them together (hot glue works, lower temp is better). Cut an 1 - 1.5" square of filter and glue
the filter on the edges, then cut an X on the back side and the air will come through, just make sure the X stays inside the filter. This will act
kind of like a one way check valve.
Just look online for mask designs, it's not hard to make them and this setup does work, I tried it and it worked as well as the mask's I've tried
before.

Realistically, it's hardly worth it - in particular, unless you can get the face fit checked, any mask is useless (except that it stops you picking
your nose).
However the idea of " my life may depend on this so I will make it from envelopes and hot melt glue" is still interesting.
Do you plan a DIY parachute too?

Don't forget the need to cover your eyes as well. Virus laden droplets can get in that way too.
Masks are better used for preventing sick people releasing virus into the air in the first place.

No BS analysis from a medical doctor regarding the covid-19 "bio-threat" and associated *security issues* generally counter-measured by the present US
Bio-Defense Strategy implemented in August of 2018, more than a year before current outbreak. Provided is insightful commentary on the SANITY and
necessity of *quarantine* practices as both a preventive and containment measure having both common sense and scientific validity.
Persons who have allowed their own personal "feelings" to irrationally accuse authorities of having mean spirited personal or political prejudicial
motives as motivation for entirely valid counter-measures to contagious diseases, such as travel restrictions, increased border security, and
quarantines ARE speaking in IGNORANCE and talking out their ass about SCIENCE they know absolutely NOTHING.
Pretenders of "knowledge" abound. But sensible more intellectually honest normal people having any COMMON SENSE would be enormously relieved if such
perceptive "regular Einsteins" would find the two brain cells needed to rub together and make that spark of "enlightenment" needed to know WHEN it
has arrived their good time to STFU.

No matter the subject, whether it is national security related to ENERGY, or to Border Security, or to Public Health the same Poisoned Intellects
imagine they are "experts".
Never let a little thing like the FACTS try to influence an idealistic radical FANATIC whose ultimate "hive mind" DYSTOPIAN "ideal" is to DEGENERATE
the entire world into a hybrid of Venezuela or Cuba merged with Caligula's Rome, where sore covered and starving street shitters mill about aimlessly
looking for the EXIT from the "utopia" that is their realized Brave New World.
The WORST "magical thinking" that has plagued this world and this country has a common denominator in the supercilious CLUELESS that are the mentally
blueprinted closed and brainwashed mind PRODUCT of decades of the "long march" of dogmatic atheistic *Marxist indoctrination* that ALL DRONES of that
IDIOT *hive mind* suffer.
That particular mass produced variety of hive mind IMBECILE are the self annointed and self appointed "thought police" who have the HUBRIS to task
themselves to
"enlighten" the rest of a critical thinking humanity and do so by every Big Lie their poisoned intellect can conceive, being a proponent of every EVIL
ABOMINATION that can be inflicted on man, woman, adult or child...as if THEY THE CLUELESS are qualified to be "leaders" of us all. What
"qualification" it is, being EXEMPLARY PERVERTS and agents of HELL trying to sell the gullible a bill of goods is EXACTLY what is represented by those
Pied Pipers followed by a HERD of equally "brilliant" like minded VERMIN.
The "critics" in the peanut gallery are a CLOWN BRIGADE of MENTAL MALFUNCTIONS.

Alright, considering that the OP hasn’t returned to this thread, it was a concept of dubious worth to begin with, and no amount of surgery is going
to save it from another descent into madness, I’m gonna pull the plug.
