These WASHABLE masks are BREATHABLE - ADJUSTABLE and each contain a pocket where you can place a filter of your choice. It is also possible to slide an N95 inside the pocket of the adult masks to prolong the life of an N95. The elastic on the masks goes around the head and is adjustable. The elastic is not sewn to the mask, but rather moves through the mask, so if you prefer elastic around the ears, you can easily convert the elastic to this style.
You can breathe safely with this non-toxic eco living friendly filter because it's not coated and has no PVCs or chemical post treatments. The soft cotton-like fabric actually gets softer with washing and dries quickly.
