Experts say people do not necessarily need to discard N95 masks every day during haze, but how often they should be replaced depends on use patterns. One outlet reports an expert saying there is no need to replace N95 masks daily when they are used for protection against haze pollution.
Channel NewsAsia adds more detail, noting that two N95 masks may be enough for about a week for some users—particularly those who wear them only for short periods such as brief commutes. It cautions that people who spend several hours outdoors may need to replace masks more frequently, implying faster deterioration from longer wear and increased exposure.
Across the reporting, the key points focus on balancing protection and practicality during haze conditions, with replacement frequency linked to duration and intensity of use rather than a fixed daily rule.
