How many layers are there in an air pollution mask?
An air pollution mask has three primary filter layers. The first one is the primary filter, which screens the larger particles like pollen and dust. Particle impurities like PM10 are trapped on this layer of the filter. However, it cannot remove PM2.5 or particulate matter with less than 2.5 microns in diameter.

N99 and N100 – these masks can filter air pollutants smaller than 2.5 microns. Among all the available air pollutants, these can filter out 99.97% of particulate matter, non-volatile liquid pollutants, dust, and fumes. Note, though, that this cannot filter oil-based impurities. These masks are available in various sizes from extra small to extra-large. These masks are also reusable for 5-6 months. However, it also depends on the severity of pollution and the usage count.

Which is better, surgical mask or cloth?
But leaving that aspect aside, it turns out that surgical masks are the better of the two, and that has to do with the engineering of the fabrics themselves. The fabric in a surgical mask is made of very tightly woven little fibers that are stuck together. You can’t see through a surgical mask. You can hold it up to the sunlight, but you can’t see through it. Whereas with a cloth mask if you hold it up you can see right through it. So when it comes to performance, the surgical mask material filters better than cloth masks.

Do surgical masks filter out particles?
Those masks do a pretty good job of filtering out the smallest particles. When you move to the low-tech solutions—the cloth masks and bandanas, or surgical masks—these often have very little effect because the particles are so small, and they can pass right through those fibers in a surgical mask or that cloth mask.
