This material is used in hospitals to wrap surgical equipment prior to autoclaving. 

Cloth masks, even with Halyard filters, are not medical equipment and should not make the wearer over-confident.   Use social distancing, avoid touching your face,  and wash hands regularly with soap.  Those in high risk situations should use FDA-approved medical equipment, not Hipp Masks. 

The mask should adhere as closely as possible to your face. Using tape can help in higher risk situations, taking care not to damage the material.   Do not touch the inside of the mask with your hands.   Fit carefully inside the mask, blue side facing out .  Trim if needed.

We recommend machine washing  your cloth mask regularly with detergent in a mesh bag (except for silk/hemp blends - hand wash or green dry clean  those). Hang or lay flat to dry.  Remove the Halyard H600 sterile wrap liner first. 

The sterile wrap liner should not be washed but should be decontaminated after 24 cumulative hours of use at least.   It can be left in the hot sun or baked in an oven or toaster over at 165 degrees F for 30 min to decontaminate. Watch  the oven the whole time, this material can melt.   Use a cookie sheet and don’t put your liner near the heating element.   Do not microwave.   Steaming or wiping the sterile wrap with rubbing alcohol or Hydrogen Peroxide are also fine.  Do not soak through. Fully dry. 

In place of sterile wrap, some suggest using blue shop towels, dried baby wipes,  fabric interfacing, or cloth polypropylene grocery bag material.  If you wish to obtain additional sterile wrap to make replacement filters, we sell it on our website.  You can also slip a medical grade face mask inside a Hipp Mask.   Any liner adds additional filtration.   Sterile wrap was pioneered for use in making face masks by Dr. Bruce Spiess, M.D., an anesthesiologist at UF Health.    For more information on this work, and to see several warnings and disclaimers that apply to these liners, please visit
