High risk of severe transboundary haze in 2023

SOS recommends each adult keep about twenty N95 which offers better protection against haze than 3ply surgical masks for haze. I also recommend MOE to distribute KF-94 masks (not KN-95 and N95 is too tight) for children below 13, everyday when haze is here.
Each N95 should cost less than $1.60 now. In normal use, each N95 can be used for 1-2 days, having 20 masks per pax, can give every one a month to react (buy more locally or overseas) when PSI goes haywire.
During the great smog of London in 1952, many died despite wearing surgicial or cloth masks because, no N95 or N99 masks. Wearing masks back then was really like for show. We will continue be threatened by haze from Indonesia and Malaysia and please bear in mind that only N95 and N99 will protect you.
