Lab Test Validates SwaddleDesigns Face Mask Efficacy

FAU researchers test a Disposable Surgical Mask, Medical Cone Mask, and demonstrate SwaddleDesigns 3-Layer cotton face mask delivers superior protection by minimizing droplet leakage and providing excellent filtration.

In June 2020, Florida Atlantic University researchers developed a Cough Emulator lab configuration to assess the efficacy of cloth masks. The FAU team published a study that shows any mask is better than no mask, but some masks are much better at stopping expelled droplets.

In July 2020, FAU researchers tested SwaddleDesigns 3-layer Cotton Mask and demonstrated its superior performance in minimizing droplet leakage from the mask and providing excellent filtration.

The FAU results were consistent with the Wake Forest study that concluded tightly woven 180 thread count cotton fabric and cotton flannel were recommended fabrics to filter particles and droplets. The WF study highlighted that masks made using cotton knit fabric, open weaves and polyester fleece fabrics are less effective. “We do not want people to think that any piece of cloth is good enough,” summarized Dr. Scott Segal, M.D., Wake Forest Baptist chair of anesthesiology, who conceived of the idea.

SwaddleDesigns Masks are designed by Lynette Damir, RN. SwaddleDesigns masks are fitted to minimize leakage around the nose, on the side of the face, and under the chin. Using the most-current research, SwaddleDesigns masks yield superior filtration of aerosolized droplets by using 3 layers of tightly woven 180 thread count cotton fabric. SwaddleDesigns face masks are comfortable, breathable, effective, with secure fit.

I would like to know how the air spreads out behind the person. How badly are the droplets and aerosols being redirected backwards, cause air still has to flow out somehow.

Repeat the test in a room with NORMAL air movement conditions. Reduce the velocity of the air to normal breathing. Direct the air through the nostrils of the test head. Repeat the test 100 times before taking the measurement for the mask, to simulate usage. You are using a new dry mask, that is absorbing some of the vapor and doing bad science.
