2 Layers of Material: The mask is made of 2 layers of high-quality non-woven fabric with a pocket for inserting a third layer (we recommend a PM2.5 carbon-activated filter insert pictured here); it has a stronger filtering effect and is more warm and breathable.
 
Please consult a physician for proper use of fabric masks. 
 
Please hand-wash your masks before use.

ONE SIZE FITS MOST PEOPLE: We are pleased to say that our face masks are suitable for adults.  These masks are tailor-made, washable and reusable.  Help keep N95 masks available to medical personnel during the publich health emergency.
