The N95 respirator can perform optimally for eight hours of intermittent or nonstop use. Regular replacement is necessary. If you find it necessary to use one because of allergies you're fucked.

I have a whole raft of allergies. Of the pages of things I got tested for, I was NOT allergic to only 2 (one was a bush I never heard of, one was a tree I never heard of). But various molds; grasses, trees and shrubs; foods; dogs, cats, feathers, horses, mice (and other critters); you name it ... yep! to 'em all.
As I said, one of my allergies is to cats. But I fostered 3 abandoned 3 week-old kittens found starving and huddled under a bush in a field about 6 years ago. And I later adopted one because he had so many health and neurological problems. Despite everything, he's a HUGE and healthy guy today! (easily 4 1/2' long stretched out).
I was wearing the masks recently to change the litter box, after the flu I had in January, because it made my airways very sensitive. This is nothing new for me. Allergies and recurrent asthma are a lifetime thing ... that nevertheless I've managed to grow really old with!

For use while shopping, when the risk of contamination is low, I would imagine the number of re-uses could be quite high.
I think there are a few things that could make the respirator non-reusable for everyday life:
So much moisture builds up in the mask, because of exhalation, that the mask becomes soggy. This might cause the fibers to stick together and the material to collapse, compromising the filtration function. The mask user would be aware of this happening.
For masks with an an exhalation valve, the valve material becomes hard, cracked, or bent and doesn't close fully. I learned to test the valve by sealing the (sanitized) valve with my (clean) lips on the outside of the mask, and blowing in. No air should be forced thru.
The elastic straps become stretched out.
The edge of the mask becomes softened and no longer seals properly.
Most of these are mechanical defects which are testable/observable.
Once you sanitize your mask (175F for 30 minutes or a 9-day cool-off period) you should be able to re-use until the mask has reached its mechanical limits.
*****
I DID look at the Chinese version, the KN95. While the filtering material meets the same specs as the 3M N95 version, the construction is very different. Overall, the CHINESE masks look softer; rather than being molded they're shaped with a vertical seam down the front, and it doesn't look like it seals well around the edges. I was going to try buying a few to see how they fit.
The group that I supervised occasionally worked with toxic samples and materials that engineering (lab hoods, air exchange) didn't accommodate, and each person had to be fit-tested with half-mask respirators, so I know all about that. The more resistance to flow thru the filtration medium (cartridge, paper) the more important the seal, otherwise the air just sneaks in around the edges. Very good filtration with poor edge seal is somewhat self-defeating ... but still better than nothing.

You know, there are EXTREMELY good, ultra-small (submicron) high flow particulate membrane filters (as opposed to depth filters) called anopore filters. Pore sizes are 0.2, 0.1, and 0.02 microns. Since SARS-COV-2 is about 0.125-0.090 microns (125 to 90 nanometres) the smallest pore size could easily even filter out individual virus particles.
They're made of extraordinarily thin aluminum oxide sheets, so they're really brittle and shatter if you try and bend them. But if you put them in a protective housing (which could be a seat-and-closure one-way valve arrangement to make them replaceable), they could be fitted into a cleanable, reusable mask with exhalation valve.
Now obviously this would protect the wearer from particulates, but not the environment from the wearer. So a cheap replaceable filter over the exhalation valve could provide two-way protection.

I heard they've developed a self-testing kit that is similar to a pregnancy test that will allow you to test not only whether or not you have COVID currently, but if you already had it and recovered.
Not sure if that's true at all because we're in the era of Post-Truth, but if it is, imagine the implications of that. Both good, and bad.
"You're free to go back to work, as long as you clear the results with us and send us a sample of your DNA along with it.", among others.
The good news is that we'd finally have legitimate death ratios instead of all the fear mongering that's been going on for months now.

So since the SARS Cov-2 virus docks onto human cells via the ACE-2 receptor (typically found in the small vessels of the lungs but also the kidneys, which explains the kidney damage that is ALSO found after Covid-19) I wondered whether the ACE receptor blockers (ARBs) would interfere with docking and blunt the infection. But it turns out that ARBs actually cause an overexpression of ACE-2 recpetors (by a factor of 3-5X) which may explain why people with high blood pressure or heart problems far so poorly: Not because of the blood pressure or heart failure but because of the medications they're taking. THAT might explain the high death rate in Italy.
I guess I wasn't the first person to think about this, there is an active discussion about this in the medical community. https://www1.racgp.org.au/newsgp/clinical/ace-inhibitors-arbs-and-covi

On the other hand, a comment buzzed past my ear while I was doing other things that soking prevented the kind of cytokine storm that quickly sent patients CTD (circling the drain). Since it was kind of random, I don't recall where I heard it, but what I found when looking it up is that according to the only studies that could be found on the topic, smoing actually RAISES the risk of severe complications and deaths. http://www.tobaccoinduceddiseases.org/COVID-19-and-smoking-A-systemati
c-review-of-the-evidence,119324,0,2.html So much for THAT idea (although I will continue to try and find the source of that comment, and any supporting info.)

I don't have any. It's something my old man mentioned yesterday. He doesn't troll the internet so I'm assuming it was some Legacy Media news source he heard it from. Just thought it was interesting and wondered if anybody heard about it. I'll see if I can find anything.

Prof Yvonne Doyle, the medical director of Public Health England, told the health select committee that finger-prick home tests would be available very soon. “We expect that to come within a couple of weeks, but I wouldn’t want to promise on that,” she said.

You can always tell when SIGNUTS is about to lie her @ss off because she'll accuse others of lying.

I know my storage limits. When we unpack groceries, the frig and freezer are full. By the next week, they're pretty empty. So I shop, once per week.
You have a fridge, 2 freezers, a pantry / storage for dry goods and you say you can't make it last for more than a week?
You must have the fattest family in California.
"When we unpack groceries, the frig and freezer are full." Both freezers?
WTF do you put in both your freezer? Whole pig? How many pounds of meat do you eat in a week? How many eggs? How many loaves of bread...how many gallons of milk do you drink in a day?
On top of which you "say" you're "also on a modified fast most of the time."
Is that the kind of fast where you eat more than usual?
You're such a lying sack of sh*t.
