QUOTE(mktan78 @ Sep 3 2021, 11:36 PM) One main reason why KF94 or surgical masks having expiry date is because the electrostatic will reduce, wear off over time. When this happened, the effectiveness of mask to filter virus particles will be impacted. Also, why the need to change masks when it get wet as electrostatic lost when got wet. Go straight for 3m n95 confirm strong electrostatic, tested myself. Other brands like Honeywell n95 i tested very very weak electrostatic. Didn't test any kf94 because n95 is cheaper and better protection. |

Got my Good Manner mask shipped by 11street korea via Lazada. Just realised that the mask has FFP1 stated on it even though it is certified by MFDS as KF94-level and by some lab as having filtration rate at 99%. Should I be concerned about it having just FFP1 standard instead of FFP2?
