How the N95 respirator works

Instead of fiberglass, single-use respirators are made from melted polymer and air-blasted into layers of tiny fibers with bigger spaces between them.

As particles fly into this maze of fibers, they get stuck. An electrostatic charge is added to the material, so even smaller particles are pulled toward the fibers, while the big holes make it easy to breathe. The longer you wear an N95 respirator, the more efficient it becomes. But breathing becomes more difficult over time as the bigger holes get clogged up with particles.
