The term fine particles, or particulate matter 2.5 (PM2.5), refers to tiny particles or droplets in the air that are two and one-half microns or less in width. Like inches, meters, and miles, a micron is a unit of measurement for distance. There are about 25,000 microns in an inch. The widths of the larger particles in the PM2.5 size range would be about thirty times smaller than that of a human hair. The smaller particles are so small that several thousand of them could fit on the period at the end of this sentence.
Valve technology: a one-way airflow vent expels condensation keeping the mask interior dry. Each valve facilitates easy breathing outwards by optimizing airflow. An easy twist seal locks the inner filter in place and blocks fine particles from entering your lungs.
It is recommended to immediately remove and discard filters after use. Wash the mask with warm soapy water and hang to air-dry. Be sure to wash your hands thoroughly.
Even with a mask, you won't be protected from everything. Having a mask is simply better than nothing. It does not guarantee invulnerability. Follow proper safety procedures and avoid areas of heavy exposure for the best possible result.
