2-D Masks vs 3-D Masks
Many lower quality masks are a two dimensional design. 2-D masks are made of a flimsy cloth layer that lies flat when you set it down. This is a problem because the human face isn’t flat. 2-D masks will almost always have large gaps around the sides, top and bottom. These large gaps will allow unfiltered air to enter and escape, greatly reducing the mask’s efficacy.
The 4521 is a three dimensional mask. It is manufactured from two layers of specially woven cotton. Each layer is woven to a different density and filters different sized particles. This design allows the mask to conform to the shape of your face and seal tightly with minimal gaps. These features greatly improve the quality of the air coming in and going out.
2 Specially Woven Layers
The Universal 4521 mask is made from two layers of 100% cotton in two different densities. The black outer layer is less dense and designed to block larger particles, while the white inner layer is denser and designed to block smaller particles. The specially woven fabric makes the 4521 highly breathable and helps it efficiently disperse moisture. This makes the mask comfortable and cool for daily wear, all day long.
