Are N95 Masks Really Effective against the flu?
A little online research will reveal that the flu virus is .17 microns in size. Clearly smaller than even N100 masks can filter out. However, it is critical to understand that the flu virus does not float in the air by itself. The flu virus is transported from patient to patient on droplets of excretions from sneezing and coughing. These particles are typically 5 microns or larger. When a sick patient wears a respirator, the respirator can be very effective at preventing infectious material from leaving the patients body, and when worn by healthy individuals, it prevents inhalation of said material. More importantly, wearing a mask is a excellent way of preventing the user from rubbing or touching their mouth or nose, which is a very high risk factor. At the end of the day will an N95 mask guarantee to protect you from the Flu? No. But it can substantially reduce your risk or receiving or transmitting the disease.
When do Dust Masks/Filters wear out?
In general, dust masks and filters should be discarded after each "encounter" or "procedure". The risk of contamination can also be heightened by removing and applying the mask multiple times. In general, once removed, the Dust Mask should be disposed of. Additionally, proper hand hygiene should be observed when touching a potentially contaminated mask. Further concern should be given to cross-contamination when wearing masks into different rooms or areas. Regardless of usage, masks should be discarded when used beyond 8 hours, and careful review and testing should be performed in regards to hazardous chemicals/particles.
Healthy people wearing masks around sick people wearing masks will still yield more cases than people without masks self-isolating.

We should have had trillions of N95's ready to go at all times, but unfortunately, the Fed can't generate them spontaneously like they can add zero's to a Goldman Sachs account.

The Netherlands has actually ordered 1.3 million Chinese masks and the HALF were useless.
