Pollution and kids: doctors explain how to pick the right mask

Paediatric experts say only certified, well-fitted respirators such as N95, KN95 or FFP2 meaningfully filter PM2.5 for children. Dr Amit Gupta of Motherhood Hospitals, Noida, recommends child-sized N95 or KN95 masks for kids above five or six, with soft inner layers and adjustable straps. Doctors warn against valved masks and choosing masks for colourful designs.
