I wish they included KN95s for comparison... I prefer them because they're easier to take on and off, and the seal seems reasonable to me (breathing in/out causes the mask to deform, so it's clearly filtering some air)
- gandalfgreybeer 5y agoAren’t KN95s just N95s with the Chinese standards (vs US standards) but should technically work for the same particle sizes?
- robjan 5y agoGP is probably referring to KF94, the Korean standard. Their form factor is somewhere between a surgical mask or an industrial / medical N95. They are quite popular, here in HK, with people who want to protect their makeup.

- micromacrofoot 5y agoTechnically yes, but US standards require a headstrap... which is generally tighter in my experience. I'm wondering if the ear loops reduce efficacy significantly (assuming fit is proper otherwise).
