Replace filters after one week of use.
Filters are not washable. In areas of high particulate exposure, filters should be replaced more frequently.
The PM in PM2.5 refers to particulate matter, also known as particle pollution. This term describes extremely small solid particles and liquid droplets suspended in air.
The 2.5 refers to the 2.5 micron measurement (and smaller) of particles that these filters are designed to capture. These PM2.5 particles are so small they can get inhaled deep into the lungs and absorbed into the bloodstream.
While our mask contains a PM2.5 filter, this mask is not intended fully filter out all particles smaller than 2.5 microns that you may encounter.
Multi-Layered Carbon Filter
Meltblown Triple Filter Layer
Melt blowing is a conventional way of making micro- and nanofibers. Unlike traditionally woven fibers, the melt blowing process weaves an intricate web for filtering gas and air.
Activated Carbon Layer
Activated carbon is an incredibly porous surface that is used in gas filtration to trap oil vapors, odors, and other hydrocarbons from the air.
Nonwoven fabrics provide a myriad of specific functions including filtration, use as a bacterial barrier, and sterility. This is why non-woven fabrics are commonly found in hospital-grade materials.
