According to 3M's comparison of disposable respirators, they consider KN95 class of respirators as "equivalent" to the N95 respirators. You can find the full details of this comparison on their website here: Link
|Certification/Class (Standard)||N95 Masks||KN95 Masks|
|≥ 95%||≥ 95%|
|Flow rate||85 L/min||85 L/min|
|≤ 343 Pa||≤ 350 Pa|
|≤ 245 Pa||≤ 250 Pa|
Why we carry KN95 masks
N95 masks are the US standards for respirator masks, while KN95 masks are the Chinese standards for respirator masks. We carry the KN95 respirator masks because they are significantly lower in price when compared to the N95 masks, yet they are equivalent in protection.
