Not durable and of questionable use. NOT a substitute for an N95.
Ok I get that they say "reusable for up to 24 hours" but why do the straps keep breaking? The box also says "not recommended for use in a clinical setting where there is significant risk level through inhalation". So basically its as KN95 that doesn't really work like a KN95. Actually, KN95 is supposed to be the equivalent of the US standard N95. An N95 FFR is a type of respirator which removes particles from the air that are breathed through it. These respirators filter out at least 95% of very small (0.3 micron) particles. N95 FFRs are capable of filtering out all types of particles, including bacteria and viruses. THIS KN95 doesn't do that!
