SMOKE PARTICLES ARE .05-1.0 MICRONS; THOSE SMOKE PARTICLES CAN FLOAT IN THE AIR FOR 2-3 HOURS. THIS MASK WILL NOT FILTER MOST OF THOSE SMALL PARTICLES; LIKE SMOKE, RESPIRATORY AEROSOLS CONTAINING COVID CAN BE LESS THAN 1 MICRON , CAN FLOAT IN AIR FOR HOURS AND WILL GO RIGHT THROUGH THAT MASK IN BOTH DIRECTIONS; THAT IS SCIENCE. TO BELIEVE THAT MASK WILL PROTECT FROM COVID IN THE LONG RUN IS TO DENY SCIENCE
