I have experience with wearing 3M masks and I found them comfortable enough for 2 hours at a time, 8 hours per day. My experience is entirely with activated carbon filters, and the inherently higher resistance of the P100 or even P95 particulate with oil filters might impact comfort significantly.
Not much more expensive; less than 2x the price that ordinary users would have paid before. Grainger still lists them for regular price, and doesn’t claim that every p100 filter is sold out yet, just the less-expensive ones. If it’s worth the extra cost to pay for a Olive/Black/Magenta filter when you just want a Magenta one… https://www.grainger.com/category/safety/respiratory-protection/cartridges-and-filters
You have experience wearing a mask like above and are telling us it’s awful to wear more than 30 minutes?

I don’t have experience with US P99/100 filters but modern European P3 filters which are between P99 and P100 have hardly noticeable resistance.
In amzon, the 2097 filtering is more expensive than before. But still available.
