PM 2.5 filters which are a special type of high-purity polytetrafluoroethylene (PTFE) membrane filter designed to capture particulates in standard EPA test methods for monitoring air quality, and RashR is now offering these filters to users with our masks.

PTFE is normally a very flexible material when made into a thin membrane, so these filters have a strong and rigid polypropylene support ring, enabling ease of handling and use. The PM 2.5 filters have a pore size rating of 2.0 microns and are tested to conform to the EPA requirement of DOP particle capture efficiency of 99.7% or better.

PM 2.5 particles are so named as they are smaller than 2.5 microns in size and represent a significant health risk to people. To compare sizes: human hair is about 100 microns across, and red blood cells are 8 microns across. PM 2.5s can travel deep into and lodge in the furthest parts of the human lung, putting people at elevated risk for respiratory and cardiac illnesses.
