Paediatric experts outline mask selection and fit guidelines against pollution

Paediatric experts recommend certified child-sized respirators like N95, KN95, or FFP2 to filter PM2.5 fine pollution particles when outdoor exposure is unavoidable.

Doctors advise parents to ensure masks completely cover the nose, mouth, and chin without visible gaps around the cheeks or nose bridge.

Children under two years should never wear masks due to the risk of suffocation, while toddlers aged two to five should use them only briefly under adult supervision.
