Alternative masks suggested if N95 hard to find
A public health expert from Universiti Malaysia Sarawak advises the public to use alternative masks like KN95, KF94, or FFP2 if N95 masks are hard to find during the haze. He notes that surgical masks offer lower protection against PM2.5 but are still better than nothing, and double masking can improve protection slightly. The advice is given in the context of the current haze situation in Malaysia.
