Bipaneled mask with a contoured design at the nose-cheek junction achieves a close fit without additional accessories when fitted with an adjustable ear loop.

Water-resistance contributes significantly to a mask designed to minimize droplet spread to the environment. Here, a bilayer, reusable fabric mask made from synthetic fabric is compared with a disposable surgical mask (PPE standard with waterproof meltblown layer). Approximately 34 drops were released over a duration of 34 seconds onto the fabric, without any leak observed, presumably simulating its ability to catch salivary droplets while speaking. PPE, Personal protective equipment.

Adequate air flow for speaking or breathing prevents uncomfortable “mask collapse” due to changes in pressure within the mask-enclosed space. This minimizes displacement and handling, which increases the risk of contamination.

Maximum skin surface area coverage at the jawline and cheeks for 3-dimensional drape over the orifices to minimize textile-skin friction and displacement.
