Developed by the Robins SPARK Innovation Hub, Robins Air Force Base, in collaboration with Mercer University and the Air Force Advanced Technology and Training Center. This community mask provides the capability to utilize recommended filter substitutes like 1500 rated or above HEPA (demonstrates minimum removal efficiency of 99.97% particles greater than or equal to 0.3 um in diamter). NOTE: There are different variaties of HEPA which utilize synthetic materials; Please ensure the material you choose does not contain fiberglass. Additional information on HEPA via NIOSC documentation: https://www.cdc.gov/niosh/docs/2003-136/pdfs/2003-136.pdf
 

The mask was printed in TPU material for mask flexibility to accommodate a better seal and with PLA for the inner filter adapter to secure filtration material. Successful qualitative fit tests were conducted at the Coliseum Medical Center, Macon.
 

The design includes a larger filter area to allow for easier breathing.
Silicone tubing was used around the inner edge of the mask to increase seal effectivenss (1/8" ID, 1/4" OD, 1/16" thickness).
 

NOTE: This 3d Printed substitute does not guarantee 100% protection against the transmission of the COVID19 and is intended to use as is. However, it will at least offer some increased protection which has been reinforced by research in materials, design, and qualitative testing.
