N95 is insufficient. You want a P100 filter cartridge; P100 will filter out oil-based and water-based aerosols, as well as all particulates. They will not filter out true gasses, but, good news!, CN, CS, and OC are all aerosols, not gasses.
Yeah there’s absolutely a rating to look for and N95 is part of that, stateside, you have niosh ratings, you’ll see these wrt industrial ppe, but there are ratings for use with CN and CS gas. My experience with them is the chemical cartridges usually have a p100 filter combined with them for particulate too. Organic Vapour & Acids are easy to get a hold of (Used these when i worked in O&G), I don’t know how well they’d work against teargas unfortunately.
I will 100% recommend north full face, a half mask is probably better than nothing but the full face gives you eye protection too. I didn’t personally like the 3m style masks, but it’s all down to personal preference, just make sure it fits correctly.
The one thing the article doesn’t cover is picking filters. Is there just a number, like N95?
Sounds like the mask might be used for paint/varnish fumes while out of lawless Federal officers’ throwing range.

3M in particular sells a lot of filters designed for particular industrial chemicals, but which might not do much for tear gas. The 60921 should work.
The Mira CBRN filters are designed for chemical warfare and should also work.
