What’s A PM2.5 Filter?

Your facegear’s replacement filter uses a 5 layer filtration design and is made of non-woven fabric and activated carbon making it durable while easy to breathe through. This 5-layer PM 2.5 filter system effectively keeps away dust particles, pollen, electrostatic particles, benzene, construction debris, hair, fine wool fibers, etc.

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 larger) of particles that these filters are designed to capture. While our facegear comes with two PM2.5 filters, it is not intended to fully filter out ALL particles smaller than 2.5 microns that you may encounter.

Filters measure approx. 12x8cm/4.8x3.15in, are compatible with most dust face coverings, and easy to insert or replace.
