How about a Still Suit with a welding helmet that omits ultraviolet light?

3. Personal protective equipment and procedures
The following PPE should be available for use by personnel providing direct care to the patient or with potential exposure to the patient’s body fluids, such as during cleaning:
Fit-tested, disposable respirators (at least as protective as fit-tested NIOSH-certified disposable N95 filtering face piece respirators), for use during aerosol-generating procedures if needed.

Isn’t this the time for the CDC to deliver the utmost correct information as possible?
I had never heard of N85 masks.
We have a generous supply of N95 masks at work, which I think will start to quickly disappear.

Obama plan eases freeze on CDC gun violence research
what size mask do I need to stop “gun violence”?
Easy... Just Google it.
Crap. I have a bunch of N95 masks. Guess I need to go buy the N100s.
Absolutely. So perhaps you'd be so kind as to point to where an actual CDC bulletin or notification refers to N85 masks? So we can ensure they correct it?
No, a hand-typed headline by a Free Republic member does not count.
It’s the N95 (N85 is a Typo) the CDC recommends which stops 3 microns size.
The Ebola will go right through your N95....You want an N100.
As an aside, Boeing’s filters are The HEPA filters are rated according to their ability to remove particulates measuring 0.3 microns, an industry standard. (according to their website)

Naturally I did that before I asked the question.
I found nothing that answers it.
.
The N95 and N100 are are rated for 95% and 99.97% efficiency against physical particles down to .3 microns. For smaller particles you’ll need a half face or full face respirator with HEPA cartridges, preferrebly a PAPR respirator. Of course no air purifying respirator is any good if you are not properly fit tested and trained on proper use.
Also keep in mind that the contaminants and micro-organisms will be on the outside of the respirator and can survive on the surface of the filter media, therefore proper training in decontamination and removal of protective wear is critical to avoid secondary exposure. I have a feeling the nurses aid in Spain was exposed by improper decontamination/PPE removal procedures.
This is also in my field of expertise. Until mold came along as an issue, filtering facepiece masks could not be called a respirator (per OSHA) as they cannot be fit tested (at least quantitative). They are not tight fitting, and particles can pass the face to mask seal.Fine for mold, which is not particularly dangerous to healthy people.
$15.99 @ harbor freight. I'll be picking a couple up this coming payday.
Someone else has probably already pointed this out, but individual virus strands are unlikely to be floating around. Rather, they’ll be in aerosolized droplets that are much larger.
8 slices is not the same as 0.08 microns Mr. Spicoli!
We're discussing Ebola, not pizza!
now , how about the rest of your body? hazmat suit?
“CDC is recommending the N95 for aerosols: spraying vomit off your car after a patient with Ebola vomits on it, power-washing the sidewalk after a liar from Liberia vomits there, etc. This isn’t for individual virus particles in the air (not believed to happen with Ebola), just for droplets that may include the Ebola virus. It makes sense. I have an appropriate number of N95 masks just in case they are needed, and I’d rather wear the N95 than deal with the discomfort of one with a better filter.”
If the droplet evaporates before it lands on something, doesn’t that just leave the virus in the air?
“Do you trust the CDC, or any other part of government”
I trust the SOB’s to get us all killed.
Some clarification is needed.
1) Ordinary ear loop masks are suitable for someone already infected, as they will significantly reduce the contamination they produce. They are not designed to protect you from other people’s contamination, so should not be thought of in that light.
2) As a rule, masks do not need to block viruses, but to block the water droplets with viruses in them. Viruses without carriers usually do not survive very long. Ebola is not known to be transmissible by air. It can, however, stay alive for days in liquid or dry form in contamination.
3) Ebola is not particularly hardy, and can by killed by a large range of chemicals, UV light, and cooking. The best protection from it is distance, that is, staying away from infected people showing symptoms.
4) Eye protection is just as important as using a respirator. Even ordinary glasses, or sunglasses, afford a lot of protection. Lab glasses and clear plastic face shields are the cat’s pajamas.
Nah. I fat fingered typing 95 on my iPhone.
Zaire ebolavirus is 0.08 microns in diameter, but 970nm in length; think of a wet piece of rope. Furthermore, because of its molecurlar weight (and inability to survive in an anhydrous environment) it must be enveloped in a droplet to be effectively transmitted. This requires the ability to bind easily to the water droplet (Ebola is not believed to do this well, but you may wish to search the primary literature for details), and be fully enclosed. This means Ebola needs a relatively large droplet- it would be difficult to design an experiment to calculate exactly how large, and because of the limited facilities and past interest in Ebola, I doubt it has been done (I'm not aware of it). Additionally, the filter elements are interwoven and multiple layered, and designed to attract/entangle things, so it's not like a single grate that you toss a bb through.
