During public health events – such as wildfires, times of high air pollution, airborne-transmissible disease outbreaks, etc. – members of the public may choose to wear a respirator to help reduce their exposure to airborne particulate hazards. When respiratory protection is recommended for workers and the public, the recommendations often focus on government approved respirators such as "N95, FFP2 or equivalent.” When used correctly, respirators can help reduce wearers’ exposures to airborne particulate hazards such as dusts, pollen, PM2.5, mists and fumes – including particles so small that they can’t be seen. Respirators contain filter material and are designed to form a seal with the wearer’s face, so that air passes through the filter (instead of around the edges) before it is inhaled. A common choice is a disposable filtering facepiece respirator (FFR), sometimes referred to as a particulate respirator, such as those shown below.
