Before anyone says "buzzfeed lol" they're actually operated separately from Buzzfeed.

Comparison chart from the 3M's website

"Based on this comparison, it is reasonable to consider China KN95, AS/NZ P2, Korea 1st Class, and Japan DS FFRs as
“equivalent” to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting
from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses)"
