I make no claims to the effectiveness of the end product. Nothing homemade will ever compare to medical grade PPE. This is a pattern of last resort. If you have access to the proper PPE use that first – obviously.

Research on the efficacy of fabric masks is conflicting. I have found peer reviewed journal articles reporting homemade cotton masks provide measurable filtration of fine particles (Disaster Med Public Health Preparedness. 2013; 7:413-418). I have also read that fabric masks may increase risks of transmission due to moisture buildup and time of virus life on fabric (BMJ Open 2015;5:e006577. doi: 10.1136/bmjopen-2014-006577). Please inform yourself as best you can.

A.B. Mask This pattern is designed to fit in two ways. First, directly over the face, similar to a surgical mask. Second, the pleats expand, allowing the mask to fit over many models of N-95 to provide a protective barrier, in the hope of extending the lifetime of the respirator. The mask can and should be washed after your shift, just like your scrubs.

I recommend using tightly woven fabric. This pattern was developed using high quality 100% cotton. Pattern listed here is to make one mask out of a fat quarter of fabric. I am confident there are better ways to cut out pieces for large scale production.

Supplies:

  • Fat quarter of 100% cotton or other tightly woven material – the tighter the better
  • sewing machine
  • iron
