It's likely that face masks, by blocking even some of the virus-carrying droplets you inhale, can reduce your risk of falling seriously ill from COVID-19, according to Monica Gandhi, MD, an infectious disease specialist at UC San Francisco.
"The more virus you get into your body, the more sick you are likely to get," she said.
https://www.ucsf.edu/news/2020/07...k-covid-19
The idea that viral dose, also known as viral inoculum, determines the degree of illness is not new, said Gandhi. Descriptions of a dose-mortality curve – how much of a virus is needed to cause death in an animal – were first published in 1938. And after all, the earliest vaccines, which were documented in 16th century China, involved exposing someone to a small amount of smallpox virus to induce mild illness and subsequent immunity.
A small number viral particles is more likely to be quelled by the immune system before they can proliferate, said Gandhi.
Researchers have studied dose dependency experimentally with other viral infections, like the flu. In a study with healthy volunteers, those who received a higher dose of the influenza A virus developed more severe symptoms.
And even now, Nasal Spray Flu Vaccine use live flu virus.
Yes, using N95/KN95/KF94, you have much less chance to get sick because it filter 95%+ of the virus. But that still leave <5% virus get pass to you. And of course with <5% virus, it is much harder to get sick. So less virus, less likely you get sick. Or in good quality ASTM surgical mask case, 60~80% less virus (reduces the "inoculum" or dose of the virus), you may still get infected but you less likely get severe symptom. If you go to hospital that full of Covid-19 positive hospitalized patients, the viral load is so high that ASTM surgical mask won't reduce enough to make much differences.
Plus if you have a weakened immune system or some kind of underlying condition (which sometime people don't even know themselves), even less virus may still get you severe symptoms (or death) so the safest is still wearing N95/KN95/KF94 and vaccinated.

Search on expiration date in reviews and few posts said the expiration date of the mask they received is Aug 2022 and they purchased the masks in March 2022.
If you keep it in right temperature and humidity, etc, probably can last a bit longer beyond expiration date.

- ASTM F1862 (Fluid Resistance)
- MIL-M-36954 C: P (Breathability)
- ASTM F2101: BFE (Filtration 3um)
- ASTM F2299: PFE (Filtration 1um)
- 16 CFR Part 1610: Flame Spread (Flammability)
Of course people would want to buy ASTM surgical mask made by legit reputable company since we know they would have completed and passed those tested in order to to mark ASTM level 1,2 or 3.
Any random face mask (note, face mask is not the same as surgical/Procedure mask for medical use) from unknown company, you have no idea how good the material they use and not sure if those mask will actually meet any standard (Breathability, filtration, etc). Like face mask that didn't pass ASTM standardize test may not be as breathable or even they have melt-blown polypropylene filtration layer, they may be using cheap low quality melt-blown stuff that don't filter that well, etc. If you google "melt blown fabric", there are good grade medical one (better filter, more breathable, etc) that are more expensive and there is low quality one doesn't filter as well and harder to breath, etc, that is cheap. Usually it is true you get what you pay for.

As for reputable seller, I think most people trust Costco better than some lesser known online store which we don't know the source of their products and may not trust their privacy policy, etc. And Costco has very good return policy.
Plus yamibuy free shipping at $50.
