PM 2.5 anti-pollution masks

PM2.5 anti-pollution masks are not Frogmask masks

They are masks made in China (on clearance), which nevertheless provide excellent protection against atmospheric pollution, with theirremovable PM2.5 filters protecting against airborne particles down to 2.5µm.

They only come in one size, but their adjustable straps behind the ears make them compatible with all shapes of men's and women's faces.

They are relatively comfortable to wear for pedestrian use, especially on public transport such as the metro, where the air is reputed to be more polluted than above ground.

These masks are compatible with all types of bicycle and motorcycle helmets.
