Protective Mask Design Features High-Flow Intake to Optimize Filter Efficiency We recommend utilizing nonwoven nanofiber materials, but even cotton cloth can provide effective protection for yourself and others against COVID-19 when used in conjunction with this mask. The low-profile filter holder typically performs better. To achieve a smooth surface that is easy to clean, print on fine layer settings (0.15mm). For disinfection purposes, submerge the mask in a 70% ethanol or Isopropyl alcohol bath for 20 minutes. This protective mask was developed in collaboration with Czech Technical University in Prague, building upon the original design by lafactoria3d.
