PM2.5 Anti-smog mask
Suspended particulate matter (PM2.5)
Particles suspended smaller than 2.5 micrometers in size possess greater penetrating power due to their small volume. They can potentially reach the walls of the bronchioles and disrupt gas exchange within the lungs. If these suspended particles also adhere to other pollutants or toxic substances, they further exacerbate the hazards to the respiratory system and can transmit adverse effects to other organs through the lungs.
