Aia kekahi ʻokoʻa ma waena o nā masks N95 a me nā masks KN95?

Hōʻike kēia kiʻi maʻalahi i ka ʻokoʻa ma waena o nā masks N95 a me KN95.ʻO nā masks N95 nā kūlana mask American;ʻO KN95 nā kūlana mask Kina.ʻOiai he nui nā ʻokoʻa ma waena o nā masks ʻelua, ua like nā masks ʻelua i nā hana a ka hapa nui o ka poʻe e mālama ai.

Ua ʻōlelo ka mea hana mask 3M, "Aia ke kumu e manaʻoʻiʻo ai" ʻo KN95 o Kina "ua like me" N95 o ʻAmelika Hui Pū ʻIa.Ua like loa nā kūlana mask ma ʻEulopa (FFP2), Australia (P2), South Korea (KMOEL) a me Iapana (DS).

He aha ka N95 a me KN95 i like

Hiki i nā masks ʻelua ke hopu i ka 95% o nā ʻāpana.Ma kēia hōʻailona, ​​ua like nā masks N95 a me KN95.

Ma muli o ka ʻōlelo ʻana o kekahi mau hōʻike hoʻāʻo e hiki i nā masks N95 a me KN95 ke kānana i ka 95% o nā ʻāpana o 0.3 microns a ʻoi aku paha, nui ka poʻe e ʻōlelo e hiki iā lākou ke kānana i ka 95% o nā ʻāpana o 0.3 microns a ʻoi aku paha.Ua manaʻo lākou ʻaʻole hiki i nā masks ke kānana i nā ʻāpana liʻiliʻi ma mua o 0.3 microns.Eia kekahi laʻana, he kiʻi kēia o ka South China Morning Post.Ua ʻōlelo nō hoʻi lākou "hiki i nā masks N95 ke pale aku i nā mea ʻaʻahu mai ka hoʻohu ʻana i nā ʻāpana ʻoi aku ka nui ma mua o 0.3 microns ka anawaena."

Eia nō naʻe, hiki i nā masks ke hopu i nā ʻāpana liʻiliʻi ma mua o ka manaʻo o ka poʻe he nui.E like me ka ʻikepili empirical, hiki ke ʻike ʻia he hana maikaʻi loa nā masks i ka kānana ʻana i nā ʻāpana liʻiliʻi.

ʻO ka ʻokoʻa ma waena o nā masks N95 a me KN95

Pono kēia mau maʻamau ʻelua e hoʻāʻo ʻia ka mask no ka kānana ʻana i ka wā e hopu ai i nā ʻāpana paʻakai (NaCl), ʻelua ma ka helu o 85 lita i hoʻokahi minuke.Eia nō naʻe, aia kekahi mau ʻokoʻa ma waena o N95 a me KN95, ma aneʻi e koʻikoʻi.

ʻAʻole nui kēia mau ʻokoʻa, a ʻaʻole nui ka ʻokoʻa no ka poʻe e hoʻohana maʻamau i nā masks.Eia nō naʻe, aia kekahi mau ʻokoʻa nui:
