An award winning mask that not only protects against air pollution but also detects it.
The 2.5 air pollution mask gives the user and the public an alert of the air quality around them. Allowing them to protect themselves from the progressive destruction that air pollution causes on the body.
2.5 has two interchangeable N95 (rated to protect against particulate matter 2.5 ) air filters on either side of the mask. Allowing users to exchange out new air filters without wasting the entire mask.
