Anaesthesia Mask + Ventilator Filter + Elastics = Snap-Together N95 Mask

The below video features a relatively comfortable, re-usable N95 (or higher) mask that can be constructed easily in minutes using “disposable” materials on hand in most hospitals. The video also includes a simple decontamination protocol, but I would be very careful to ensure that you do not apply alcohol to the filter media, as contact with alcohol will usually destroy a significant portion of the filter’s capability.

The concept is excellent. But the average person does not have access to anaesthesia masks or ventilator filters. In a follow-up post, I will document my development of a similar N95 mask using a commonly available CPR pocket face mask.
