Why Children and Pregnant Women Should Avoid N95 Masks

When haze hits, wearing a mask is a common sight, but simply putting one on isn't enough to keep those tiny PM2.5 particles out. To get the protection you need, you must ensure your respirator is genuine, well-fitted, and worn correctly .

Why your mask choice matters

Not all masks are created equal. While 3-ply surgical masks are great for other uses, they are too loose to block the fine airborne particles found in haze . For effective protection, the Ministry of Health recommends a particulate respirator like an N95, which is designed to seal closely to your face and filter out at least 95% of particles .

Getting the perfect fit

A respirator only works if air is forced through the filter rather than leaking around the edges. Before you head out, wash your hands and inspect the mask for any damage or dirt . Position it over your nose, mouth, and chin, then shape the nosepiece with both hands—avoid pinching it with just one finger. Ensure the straps are secure and check for any gaps where air might sneak in .

Watch out for facial hair

If you have a beard or moustache, take note: facial hair can break the seal between your skin and the respirator, allowing contaminated air to leak inside . For the best protection, the sealing edge needs to be in direct contact with your skin .

Who should be cautious

Respirators can make breathing feel more difficult, which might cause discomfort or headaches for some. The Ministry of Health advises that N95 masks are not suitable for children or pregnant women . If you have heart or lung conditions and feel uneasy while wearing one, stop and consult a doctor .
