When haze hits, it is natural to want to protect yourself from the fine particles in the air. However, not all masks are created equal, and knowing which one to choose can make a significant difference in your respiratory health [1, 2].
Why surgical masks fall short
While 3-ply surgical masks are common, they are not designed to filter out the fine particulate matter, such as PM2.5, that makes up haze [1, 2]. Because they are loose-fitting, air often leaks through the gaps around your nose, cheeks, and chin rather than passing through the filter [1, 2]. Malaysia's Ministry of Health explicitly notes that these masks do not provide sufficient protection against the small particles responsible for haze [1, 2].
The N95 respirator as a gold standard
For those who need to be outdoors, a genuine, well-fitting N95 respirator is the recommended choice [1, 2]. These respirators are certified to filter at least 95% of airborne particles when used correctly [1, 2]. Other options like KN95 and KF94 respirators can also be effective, provided they are legitimate products that meet their respective certification standards and fit your face closely [1, 2]. Always check for proper markings and buy from reliable retailers to avoid counterfeit products [1, 2].
The importance of a proper fit
A respirator is only as good as its seal. To ensure it works, the mask should cover your nose, mouth, and chin without any gaps [1, 2]. Before heading out, perform a quick seal check by breathing in and out to ensure air isn't leaking around the edges [1, 2]. Remember that facial hair can interfere with this seal, potentially lowering the mask's effectiveness [1, 2].
Who should be cautious?
Respirators increase breathing resistance, which can cause discomfort, tiredness, or headaches [1, 2]. The Ministry of Health advises that N95 masks may not be suitable for young children or pregnant women [1, 2]. If you have chronic heart or lung conditions and feel uncomfortable while wearing one, it is best to stop and consult a doctor [1, 2].
Prioritise reducing exposure
A mask is not a licence to stay outdoors indefinitely. The best way to protect yourself is to reduce unnecessary time outside and avoid strenuous activities when API levels are high [1, 2]. Always check the latest readings on the official Air Pollutant Index Management System (APIMS) before planning your day [1, 2].
