Air Pollution Masks

Air Pollution Masks

Face masks that filter out airborne particles can make a big difference in your exposure to air pollution. A mask with a high quality filter that fits properly can be an effective measure against the inhalation of harmful pollutant particles as small as PM 2.5.


Not all masks are effective against breathing in small pollutant particles. Here’s what you need to consider:

1. Look for a mask with U.S. NIOSH or EU FFP ratings:certification and ratings on a mask are important – they indicate that the mask has been tested and meets benchmark standards to filter out small airborne particles.

  • N95, N99 or P100 rating – is a U.S. government-approved certification from the U.S. Centers for Disease Control and Prevention (CDC) National Institute for Occupational Safety and Health (NIOSH). The NIOSH N95 certification, for example, means that the mask should filter out 95 percent of particles greater than 0.3 microns, which is much smaller than PM 2.5.  N99 respirators filter greater than or equal to 99 percent of these particles.
  •  EN 149 FFP2 or FFP3 rating – is a European Union tested rating standard.

2. Make sure the mask fits securely and that there are no gaps to let outside air in. A gap in your mask that allows air in completely negates any benefit or protection you would get from filtering out pollutant particles.

3. Check the mask’s material to ensure that it can filter out small particles.

4. Make sure your mask is well ventilated.
