Great observation/question! And those two sources you cited in your later post,
BET7 (
https://www.thearmorylife.com/forum/threads/corona-tracker.897/page-3#post-17995), are excellent, and both describe the issues concerning "masking up" correctly.
To summarize for folks reading here:
Masks - currently - need to be separated into two types:
Nuisance - or "dust" - masks versus respirators.
ehs.msu.edu
The masks that you're used to seeing on TV or at your local hospitals (before COVID-19) on doctors and nursing staff are of the former. It's main use is as a barrier against larger and/or non-toxic particles. Normally, it's used by folks who may have allergies to guard against animal dander or plant pollen. In the healthcare setting, these types of masks are used typically contain aerosolized particles to the person wearing it: this is why you'll see during even the normal flu-season in many doctors' offices a request for those who come in with cold/flu symptoms to mask-up and sit apart from those who are otherwise well. With COVID-19, the idea is to have symptomatic individuals wear these masks so that when they cough or sneeze, what they expel is contained within.
The latter - what you've been hearing a lot about recently as "N95" - is meant more to filter and protect the wearer. In order to accomplish this task, it needs to fit well to the wearer's face.
And here's where the troubles mainly lie, especially with "expired" masks.
^
SMSgtRod, I don't know if what you have are N95s - and if they are, they may be bordering on the line of "expiration" (given that you bought them 4 years ago, and the likelihood of them having sat on the shelves at your retail source).
The nose piece/bridge and straps may both be damaged and/or degrade faster than the mask filtration material itself, and should either of these issues occur, the critical fit/seal will be breached, rendering the mask less effective.
The other issue is as alluded to above - damage to the filter material.
These factors can all be mitigated through correct storage, but still, degradation can occur due to father time alone. A good visual inspection and common-sense should tell the end-user if the masks is operable or not.
A "user seal check" should be performed whether using masks in or out of their expiration dates, and it should be performed EVERY time you don a mask (don't mistake this for a true "Fit Test," however; the user seal check is just a field-expedient method to see if you have a reasonably proper fit, but is no guaranty of such) ----->
^ Note that this is a general-purpose video. The packaging of your chosen mask should provide proper donning procedures as well as its specific user seal check procedures.
Here's a couple of good references on this concern:

^ Which references:
Coronavirus Disease 2019 (COVID-19) (which in-turn references the above user seal check.
And 3M's little write-up is a good one for the "tl:dnr" crowd ---->
Why Do Disposable Respirators Have a Defined Shelf Life? |
So, the next logical question would be why would a mask that's still in its original, sealed, packaging "expire?"
My suspicion is that a lot of this is workplace related: workplace storage measures, while it may still allow for individually sealed packages to remain "sterile," may expose the units to other factors which could degrade various aspects of its physical structure.
Temperature swings can be drastic in a warehouse setting if not climate controlled. Similarly, an opened "dispenser box" (think point-of-sale equivalent for retail) can potentially be exposed to sunlight/UV. Vibration may also be a concern (settling of materials over time - while this last one is pure speculation on my part, we do see an equivalent in this with long-term stored "car gun" ammo).
For those of us who prep, if we've folded what was supposed to be a flat-packaged mask for long periods (say, to allow for storage in a "go/bug-out/get-home bag"), things can happen to that material, too.
As for why Asians "mask up,"
@BET7 , I think this requires a bit of perspective.
A member on XDTalk wrote the following:
I replied as-follows:
I think you'll find it both somewhat ironic as well as perhaps a relief to know that the mask this person was wearing actually better helps protect you than him, if he indeed was sick (forget COVID-19, let's talk about the more immediate threats of influenza and just whatever upper-respiratory bug is going around in your area
). That mask serves to catch whatever that person sneezes or coughs out. (
And this is why those of us who prep should still purchase these types of masks: so that the ill in our household can mask-up and limit exposure to their loved ones.)
Unless that person was wearing an N95, that mask is offering less protection to them than it is helping keep their spittle and nasal discharge contained within (i.e. to
them). This is why you'll find signage at doctors' offices, clinics, and hospitals instructing those with flu-like symptoms to don a "surgical"/nuisance mask - it's to protect the other patients as well as healthcare workers
from them.
Also, I think it will be helpful for me - as someone who is a first-generation immigrant from Taiwan - to explain a bit why there's been such a crazy run on various "masks" in Asia (as well as various heavily Asian-populated areas in the US, such as where my father lives in Atlanta, GA).
This is because these types of "surgical"/nuisance masks have always been very much a part of daily life in a lot of Asian countries. A part of this is because of the poor air-quality in these rapidly industrializing countries (and no, we're not talking about smog in the way LA has smog - we're talking full-on even healthy adults have a hard time breathing soup-air:
New Delhi pollution: India's capital chokes on smog as crop burning continues - CNN). The other part is because germophobic folks see this type of mask as a basic need, kinda like how you'll find those knit white cotton gloves being worn by nearly every service-industry person in those same communities, even though in many instances it offers absolutely no health/sanitation advantage to either the wearer or those whom they are serving.
It's just folk-belief. Kinda like other Asian beliefs like sleeping with the window open or with a fan blowing on you will cause you to die (the wind will snatch away your breath), or that drinking anything other than warm water will cause you anything from gastrointestinal distress to "blood upset" (I have yet to figure out what that one is, despite - or maybe in spit of? - western medical schooling)
So, just how prevalent was masking-up in the days before COVID-19?
Many banks and other sensitive structures in Asian countries have embossed plaques adjacent to entry points that remind patrons to please remove their masks and/or helmets (mopeds, bikes, and motorcycles are popular and cheap means of transportation).
Yes, it's like that!
Unfortunately - and this bothers me because I
am a first-generation immigrant - a lot of "Fresh off the Boat" (FOB) immigrants/tourists and even first-generation folks fail to realize just how scary this can look to westerners: many of whom until the outbreak of coronavirus probably have seen plenty of Asian folks masked-up, but who may not have registered it as anything other than perhaps "oh, that person must be sick/immunocompromised." And doubly so because of what's happening in the world today.
