You are selling masks, so misleading claims would benefit your sales. Please understand your claims are taken with a grain of salt. Anyone with a modicum of sense would seek an independant source to validate this. Respirator masks of the highest level are the only masks that offer consistent noticeable protection against viruses is the consistent message given by research outside of mask vendors and government agencies
It looks like somebody got a decimal wrong on here! The Most Penetrating Particle Size is 0.3 microns, not 3.0 microns!

Filtration Efficiency: This refers to a mask’s ability to filter out particles, typically measured as a percentage. The higher the filtration efficiency, the better the mask is at trapping particles. Commonly used metrics include Particle Filtration Efficiency (PFE), Bacterial Filtration Efficiency (BFE), and Viral Filtration Efficiency (VFE). Higher-rated masks generally have higher filtration efficiency.
The effectiveness of different masks at preventing the spread of respiratory droplets and reducing the risk of exposure to the SARS-CoV-2 virus, which causes COVID-19, can vary based on the mask’s material, design, and fit.
One commonly used rating system is the N95 rating, which is used by the National Institute for Occupational Safety and Health (NIOSH) in the United States. N95 masks are designed to filter out at least 95% of airborne particles, including those that are too small to be seen by the naked eye. They are considered to be highly effective in preventing the spread of respiratory viruses such as COVID-19.
