For particulates you should use a real N95 instead of KN95. If you want something more permanent try a half-face or full-face respirator with replaceable cartridges. I have a 3M 6297 (https://www.3m.com/3M/en_US/p/d/b10013131/ ). I'm not convinced the particulate reduction is any better than an N95, but it's easier to get a good seal and easier to breathe through, and gives more odor reduction. If doing it again I'd probably get the style with the trapezoid shaped cartridges (https://www.3m.com/3M/en_US/p/d/b5005625039/) instead of the round ones, since there are more choices of cartridges for different classes of contaminant. As an extra benefit, it gets you the stylish Darth Vader look. You can get them at hardware stores or Home Depot since painters and so on use them. I got mine at Office Depot. I think it was $25 or so including a pair of P100 cartridges.
The filter cartridges last a pretty long time but they are way more expensive than N95's, like $10 a pair maybe? IDR, it's been a while.
Don't worry about N95 vs N100/P100, there really isn't much difference under testing. Look up Aaron Collins' youtube channel for a gazillion mask tests from 2020 or so. N95 vs P95 shouldn't matter since the P designates oil resistance which isn't relevant here.
Here are 3M's full face respirators which is the next step up from half face: https://www.3m.com/3M/en_US/p/c/ppe/respiratory-protection/reusable-respirators/full-face/
I don't have one but sort of wanted one some time back.
At least on my 6297, it looks pretty easy to convert it to a powered respirator (PAPR) by removing the cartridges and connecting an air hose to the cartridge ports to deliver filtered air from wherever.
The GVS Elipse is a lower profile option that should have comparable performance to the 3m respirators. They offer both half and full face respirators as well.
Yes there are lots of brands. The Elipse got a poor review on reddit a while back, but I haven't tried it myself.

I have one. I used it quite a bit during COVID. I think 3m's respirators might flow a little better, and its easier to find their filters. I didn't have any issues with the seal or comfort on the GVS. And I appreciated the smaller profile. Not sure what the complaints were on rediit, but I like mine.
The Dräger Explore 3300 or 3500 are also good options with replaceable filters. When I bought mine it was actually cheaper than the 3M mask, though I live in germany where the company is based and not in the US.
