How to Make a CDC-Approved Face Mask For Double Masking
A fabric face covering can be worn over your disposable medical mask to help prevent you from spreading Covid-19. Here's how to make one of your own.www.wired.com
Disclaimers - For it to work effectively, it would need proper fitment, it isnāt as good as an n95 mask, itās not a replacement for good handwashing, itās to protect others from you possibly infecting them (and not the other way round) etc. It would be worth mentioning also that how someone puts on and takes off and stores a mask is important also, to avoid cross infection through handling etc.
Probably the best mask making video. Thanks for the heads up @Daniel Kutscherā©. Needless to say, it was made by an Australian. Yay us.

Research published in the New England Journal of Medicine last month (https://www.nejm.org/doi/10.1056/NEJMc2004973), showed this coronavirus can stay viable for up to three days on hard surfaces like stainless steel and plastic.Under experimental conditions, it found that the virus remained viable in air for the entire three-hour experiment.
On surfaces it was more stable on plastic and stainless steel, than it was on either copper or cardboard.
No viable SARS-CoV-2 was detected on the copper surface after four hours, and on the cardboard surface after 24 hours.
Whereas it was still able to be detected up to 72 hours later on the stainless steel and plastic surfaces.
But it's also important to remember that doesn't mean it's as infectious as when it was first deposited.

re: Face shields
Community Use of Face Shields to Contain COVID-19
This Viewpoint discusses the prospect that face shields might be more effective than face masks at reducing community SARS-CoV-2 transmission and calls for rapid adoption of face shield-wearing by the public as an infection control strategy.
jamanetwork.com
Most important, face shields appear to significantly reduce the amount of inhalation exposure to influenza virus, another droplet-spread respiratory virus. In a simulation study, face shields were shown to reduce immediate viral exposure by 96% when worn by a simulated health care worker within 18 inches of a cough.10 Even after 30 minutes, the protective effect exceeded 80% and face shields blocked 68% of small particle aerosols,10 which are not thought to be a dominant mode of transmission of SARS-CoV-2. When the study was repeated at the currently recommended physical distancing distance of 6 feet, face shields reduced inhaled virus by 92%,10 similar to distancing alone, which reinforces the importance of physical distancing in preventing viral respiratory infections. Of note, no studies have evaluated the effects or potential benefits of face shields on source control, ie, containing a sneeze or cough, when worn by asymptomatic or symptomatic infected persons. However, with efficacy ranges of 68% to 96% for a single face shield, it is likely that adding source control would only improve efficacy, and studies should be completed quickly to evaluate this.
