2.5 microns is pretty darn small — less than a third of a human hair! The included PM2.5 filter can handle particles that tiny. Even with daily use, the filters are effective in filtering out PM2.5 for up to a week thanks to the multi-layered non-woven fabric construction and activated carbon layer.

Done with your filter? They’re recyclable!

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.

Non-Woven Fabric

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.
