Why Children and Pregnant Women Should Avoid Wearing Tight Respirators

When air quality drops, choosing the right face mask is essential for your health. While many options exist, not all masks provide the same level of protection against the fine airborne particles that characterise haze.

Why surgical masks fall short

If you are relying on a standard 3-ply surgical mask to block haze, it is time to reconsider. These masks are designed to be loose-fitting, which allows air to leak in around the edges rather than passing through the filter. Malaysia's Ministry of Health notes that surgical masks do not effectively prevent the inhalation of the small particles responsible for haze .

The role of N95 respirators

For adults who need particulate protection outdoors, a genuine, well-fitted N95 respirator is the clearest choice recommended by health authorities. These respirators are designed to form a close seal around the face, ensuring that inhaled air is drawn through the filtering material . It is important to note that while these masks filter particles, they do not protect against gases or vapours .

Considering KN95 and KF94 alternatives

Genuine KN95 and KF94 respirators can also be reasonable options for haze protection. A KN95 is manufactured to a Chinese standard, while a KF94 follows a South Korean standard requiring at least 94% filtration efficiency. However, their effectiveness depends entirely on whether the product is legitimate and fits your face properly. Always check for clear branding and buy from reliable retailers to avoid counterfeit products .

Important precautions for wearers

Respirators can make breathing feel more difficult, which may cause discomfort or headaches. Because of this, they are not considered suitable for young children or pregnant women. Furthermore, individuals with chronic heart or lung conditions should consult a doctor if they feel uncomfortable while wearing one. Always prioritise reducing unnecessary outdoor exposure when air quality is poor .
