BEWARE: Not all P2 respirators are the same!
Not all masks give protection against viruses.
Surgical masks are primarily made to stop moisture or particles going outwards; they are not really designed to filter air coming in.

It is claimed Nano-Silver Filters actually kill viruses
Nano-silver can transform protein expression and generate reactive oxygen species (ROS). This damages the DNA of germs and kills them. Nano-silver can kill a wide range of germs. Medical grade nano-silver coatings eliminate 99% of all airborne bacteria and viruses.
COVID-19 transmission messages should hinge on science
"The precautionary principle suggests we should approach this organism as we would any novel highly transmissible respiratory disease-as a contact, droplet and airborne disease, but with one important caveat:
Short-range aerosol transmission is also a strong possibility."
Aerosol and Surface Stability of SARS-CoV-2 as Compared with SARS-CoV-1
"Our results indicate that aerosol and fomite transmission of SARS-CoV-2 is plausible, since the virus can remain viable and infectious in aerosols for hours and on surfaces up to days (depending on the inoculum shed)."
Some 'pandemic' P2 respirators, 3M-8210 or 3M-8110s, from the national emergency medical stockpile were given out as a result of the bushfires.
On the 22 January 2020 and in the face of a possible pandemic - One million P2 masks were ordered as authorities respond to the Wuhan coronavirus
On  28 January 2020 The National Medical Stockpile has 12 million masks
Health Minister Greg Hunt said there was a national medical stockpile of 12 million masks which would be sent where they were needed.
Chief medical officer Brendan Murphy stressed there was no need for members of the public to wear masks.
Meanwhile, A top US health official says the US needs 300 million face masks for healthcare workers
“Health and Human Services Secretary Alex Azar said the US needs at least 300 million face masks for healthcare workers as the country braces for the rapid spread of the coronavirus. Azar said the US already has 30 million but needs 270 million more.
N95 respirators are not the best way for everyday people to prevent infection because they can’t fully filter out the airborne coronavirus particles, but they are recommended for healthcare professionals”?

Study highlights ease of spread of COVID-19 viruses
"The findings confirm that COVID-19 is spread simply through breathing, even without coughing, he said. They also challenge the idea that contact with contaminated surfaces is a primary means of spread, Osterholm said."
Is the air quality on a plane ok?
"As many recent air quality studies have shown, the cabin is a healthful environment, meeting all applicable safety and health regulations and standards."

Hospital Workers Make Masks From Office Supplies
"Providence infection control and quality experts designed prototype face-shields with off-the-shelf materials: marine-grade vinyl, industrial tape, foam and elastic. Monday night they bought supplies at craft stores and Home Depot. On Tuesday, about 20 administrative staff members at the health system’s corporate headquarters volunteered to work an assembly line in a large conference room, putting together 500 home-spun face shields"
Mass masking in the COVID-19 epidemic
"The WHO recommends against wearing masks in community settings because of lack of evidence. However, absence of evidence of effectiveness should not be equated to evidence of ineffectiveness, especially when facing a novel situation with limited alternative options."
"Furthermore, transmission from asymptomatic infected individuals has been documented for COVID-19, and viral load is particularly high at early disease stage. Masking, as a public health intervention, would probably intercept the transmission link and prevent these apparently healthy infectious sources."
Lancet study recommends masks:
"
In addition, vulnerable populations, such as older adults and those with underlying medical conditions, should wear face masks if available. Universal use of face masks could be considered if supplies permit."
Nano-filter extends life of masks worn to avoid coronavirus
A research team in South Korea has developed a nano-filter that could extend the life of face masks being worn extensively because of coronavirus (Covid-19).
Q: Should we be reconsidering the role of masks given that an “absence of evidence of effectiveness should not be equated to evidence of ineffectiveness”?
A: “...we don’t have the supply chain for everyone to have them and the hospitals need them.” -
Professor Bruce Thompson, Dean of Health at Swinburne University.

After reading the studies below, coronavirus can be spread by aerosols, not just by droplets or touch. Coronavirus can live in the air for 3 hours.
Viability in air:
"A very recent study found that SARS-CoV-2 aerosols remain viable for up to 3 hours, which is similar to the viability of SARS-CoV in air and MERS-CoV.
This is adequate time for exposure, inhalation, and infection to occur both near and far from a source."

Therefore, cleanairtas believes suitable respirator masks or face coverings (worn by BOTH those affected AND those unaffected out in the community) do have a place in preventing the spread of this virus.
This virus is like electricity, you cannot see it in the early stages but if it gets hold of you it could kill you and in turn kill others. We all have to behave and act responsibly and if this means us all wearing a mask or face covering to prevent potential transmission to ourselves and others the better for all.

As at the 24/3/2020 - N95 respirators and surgical masks were available on eBay.
Search on 3M-8210, find a good price and you could have them in less than 10 days.
If you have, or could have the virus (and you will never know in the early days of infection) a non-vented (non-valved) N95 respirator is a must.
A valve assists in quick exhalation of CO2, and heat, from your mask making it more comfortable to wear, but is a no no if you have the virus!
Only wear a vented respirator if you are absolutely sure you have not been near an infection source in the last two weeks, or have had a negative test.
A respirator may provide protection against multiple modes of transmission, including droplet, airborne and hand-to-mouth/nose transmission.

Surgical type masks may not stop you catching the virus. They do not mate-to-the-face of infected people; they do not mate-to-the-face of uninfected people.
Surgical type masks do stop you touching your face which is good,  but by design they cannot provide the same sort of protection as a N95/P2 respirator when fitted properly.

WHO considers changing guidance on wearing face masks
The World Health Organization is considering changing its guidance on whether people should wear face masks in public, prompted by new evidence that suggests doing so could help contain the pandemic.
Czechs facing up to COVID-19 crisis by making masks mandatory
A regulation issued on 18 March made it compulsory to wear either a surgical face mask or other mouth and nose-covering apparel when in public, one of the few countries in the world to issue such a demand.

US moves toward broader promotion of masks.
The Trump administration is formalizing new guidance to recommend that many, if not almost all, Americans wear face coverings when leaving home, in an effort to slow the spread of the new coronavirus. Officials would suggest that non-medical masks, T-shirts or bandannas be used to cover the nose and mouth when outside the home. Medical-grade masks, particularly short-in-supply N95 masks, would be reserved for those dealing directly with the sick.
Fauci 'puzzled' by how virus affects healthy people differently.
“The top U.S. infectious disease official says medical experts are no closer to figuring out why some seemingly healthy people infected by the new coronavirus develop only mild or no symptoms but others become very sick.”
Anyone may be a considered a carrier, whether they have symptoms or not.
In response to recent studies, the CDC on Wednesday changed how it was defining the risk of infection for Americans. It essentially says anyone may be a considered a carrier, whether they have symptoms or not.
Scientist’s plea for Australians to wear masks    Face coverings.
Jeremy Howard, an Australian researcher who works at the University of San Francisco, was speaking on the Today show this morning.
He has started a campaign called Masks4All that aims to encourage people to wear masks in public despite current advice that they are of little use unless someone is infected.
masks4all  -  Make and wear a home-made mask to slow the spread
“Analyses show that if 50% of the population were to wear masks, only 50% of the population would be infected by the virus. Once 80% of the population wears a mask, the outbreak can be stopped immediately.”

How hospitals can decontaminate and reuse scarce N95 masks - Stanford News

“As health workers and first responders in the United States try to stem a pandemic without adequate protective gear, health officials are forced to consider a stopgap - decontaminating and reusing N95 masks to shield those whose jobs expose them to the virus that causes COVID-19.”

CDC advises Americans to wear non-medical masks. = Face coverings.
"The White House says the Centers for Disease Control and Prevention is recommending that Americans cover their faces when leaving the home, especially around other people. The latest guidance suggests that Americans use makeshift coverings, such as T-shirts, scarves or bandanas to cover their noses and mouths. Medical-grade masks, especially N95 masks, are to be reserved for those on the front lines of trying to contain the pandemic. The policy change comes as public health officials are concerned that those without symptoms can spread the virus which causes COVID-19."

But here is an even easier way… Check it out!
Masks may be good, but the messaging around them has been very bad
That’s one of the arguments in favour of masks for everyone: if people who aren’t visibly sick can still spread the virus, asking everybody to wear a mask may block their virus-laden exhalations from entering a space. In addition, if the tiny droplets full of virus linger in the air, wearing a mask might stop people from breathing them in.
We are constantly being told NOT to wear facemasks for COVID-19.
The World Health Organization (WHO) is telling the general public not to wear face masks. Why?
The main reason according to authorities is because there is a shortage of masks and respirators and these are required for front-line workers.
Agreed, but face masks for front-line workers are supplied from our national medical stockpile and people sourcing their own certified surgical masks or P2/N95 respirators should not reduce these numbers in any way for front-line workers.
To bolster the argument not to wear face masks, it is wrongly being claimed masks are ineffective. If they are ineffective for the public then it follows they must be ineffective for front-line workers but this is not the case.
Both front-line workers and the general public must know how to put standards approved P2/N95 respirators on, correctly take them off, and to perform face-fit checks to get the best protection but not everybody is trained how to do this.
Study - Coronavirus can travel much farther than previously thought
The scientists based their findings on a Jan. 22 case of a person with the virus who took a long-distance 48-seater bus ride - and ended up infecting 13 people total. Surveillance footage showed that the patient didn’t interact with others throughout the four-hour ride - but a couple of the people who became infected were sitting as far as six rows away, or about 15 feet, the researchers said.
Turbulent Gas Clouds and Respiratory Pathogen Emissions: Potential Implications for Reducing Transmission of COVID-19
Peak exhalation speeds can reach up to 33 to 100 feet per second (10-30 m/s), creating a cloud that can span approximately 23 to 27 feet (7-8 m). Protective and source control masks, as well as other protective equipment, should have the ability to repeatedly withstand the kind of high-momentum multiphase turbulent gas cloud that may be ejected during a sneeze or a cough and the exposure from them. Currently used surgical and N95 masks are not tested for these potential characteristics of respiratory emissions.
However, there is mounting evidence that just a simple face covering worn by the public can slow the spread of Covid-19.
