Amazing as it may be, Popular Mechanics actually published such a design for an “Emergency Wooden Respirator” in the Golden Anniversary issue in January 1952. The Journal of the American Medical Association also published an article on the same subject. JAMA. 1951;145(7):485. doi:10.1001/jama.1951.72920250005008b.
In 2011, The Rotary Club built a wooden respirator to this design. Video Link https://www.youtube.com/watch?v=wmwKo4BQ5rs
