Any alternative solutions?
One time, as a child, I needed to go into a house with smoke damage. The smoke damage was affecting my breathing. Otherwise, it was safe to go in.
I made an improvised mask using Kleenex and tape. Apply the tape to all four sides to make a complete seal. In this situation, it worked. However, I can't make any claims on the effectiveness of the MacGyver mask in this situation.
