You can never truly know thousands where given to solders in the First World War. In the Second World War even more where give to solders and civilians. Then in to the Cold War Russia and the USA made millions and today almost every modern army has some sort of gas mask. My answer is that as much as a billion where given out or sold but many will not give any protection or contain asbestos.
Some countries were afraid of gas attacks being used against them, so masks that could protect the people were manufactured and spread.
Over 4.5 billion.
You don't put gas into gas masks. They are used to keep out poisonous gases.
