The masks are also perfect when you only go outdoors during heavy pollen seasons. Also ideal when smoke, smog, or air pollution is dense.

Therefore, it helps to block larger particles, while the inner white layer is dense and built to prevent smaller particles. The specially woven fabric renders it extremely breathable and efficiently helps spread moisture. Thus, these masks feel comfortable and cool to wear all day.

2-D vs 3-D PPE

Many protections of a lower quality are crafted in two dimensions. 2-D covers include a flimsy fabric that lays flat as you put it down. That’s an issue because the human face isn’t flat. These have more significant gaps nearly always around the sides, top and bottom. Such full holes allow for the entry and exit of unfiltered air, significantly decreasing the mask’s effectiveness.
