PM2.5 Face Mask Filters - 10 Pieces
5 Layer PM2.5 Filters with Activated Carbon
PM stands for Particulate Matter and 2.5 represents the size in micrometers. PM 2.5 helps filter out airborne particles that are as small as 2.5 micrometers in diameter. In comparison, the average human hair is about 70 micrometers in diameter which makes it about 30 times larger than a particle that is 2.5 micrometers in diameter. Most solid and wet particles like to cling on to each other. Our PM2.5 face mask filters help block most types of air particles from entering your body.
Our PM2.5 face mask filters are made with 5 layers consisting of high efficiency non-woven fabric, melt blown fabric and activated (carbon) charcoal fiber.
The first layer is made out of non woven fabric which doesn't have small holes like woven material.
The second layer is made out of melt blown fabric which helps with filter, provide a bacterial barrier, repel water and liquids, sterile, cushioning, strength and is washable.
The third layer is made with activated carbon fabric that is widely used in industrial, medical and defense applications.
The fourth layer is another layer of melt blown fabric which sandwiches the activated charcoal layer in the middle for maximum filtration efficiency.
The fifth layer is another layer of non woven fabric. Please note that this material is made out of high efficiency non-woven fabric that allows for better air circulation and is skin friendly.
When used with the right face mask with filter pockets, you can get high quality protection. We have the perfect face mask for these filters that is reusable, washable and affordable. Please see our other listings.
