Here are the elastic masks we have available! (You get a mask with a filter already inserted, 1 spare filter and 2 nose clips). All of these are sized at medium/large which was a standard, average adult size mask.
These are full face masks that cover from nose to chin and have elastic that goes around the back of the ears.
The inside material is bamboo cotton. The outside layers vary, but most are cotton or cotton twill. There is a space between these two materials where a filter is inserted (the filter is also sewn to contour to the mask). The mask is washable. We did a lot of research on these and used the materials that commercial mask makers are using with a pattern that fully fits the face.
To use, put elastic around your ears and you're ready to go :) You can attach the bendable nose clamp once you're wearing the mask to give a tighter fit (remove backing on nose clip and place, sticky-side to mask, over the bridge of the nose and mask, then bend to form fit around your nose).
After as much use as you are comfortable with (hours or days if you hang it properly without contamination), remove mask carefully and discard filter, put mask in to wash with normal clothes (we suggest inserting mask into a mesh bag to prevent cords from tangling with your clothes). If you use the nose clip, we recommend taking it off and either saving it to use again or replacing it (the stickiness will wear out). Replace filter and you're ready to go again.
