Mask design to improve safety for sip and puff users. PPE option for medical grade devices to be adapted for sip and puff users. This instruction is specific to NK95 masks. These instructions can be used with N95 masks and standard surgical masks.
We do not recommend cleaning the NK95, N95, or surgical masks. Once soiled we recommend disposing of the mask and saving the silicone grommet for the next modified mask created. Modified cloth masks can be hand washed and air dried.
