Airborne toxic materials may be gaseous (for example, mustard gas and chlorine gas) or particulates (such as biological agents). Many filters include protection from both types.
The first gas masks mostly used circular lenses made either of glass, mica or cellulose acetate. With the exception of the latter, these materials were quite brittle and needed frequent replacement. Later on, the Triplex lens style (two layers of glass and one layer of cellulose acetate in between)[1] became more popular, and alongside the simpler cellulose acetate they became the standard into the 1930s. Panoramic lenses were not popular until the 1930s, but there are some examples of those being used even during the war (Austro-Hungarian 15M). Later, polycarbonate started being used for its strength.
Some have one or two filters screwed (via inlets) onto to the gas mask while others have a large filter (coffee can filter) connected to the gas mask with a hose that is sometimes confused with an air-supplied respirator in which an alternate supply of fresh air (oxygen tanks) is delivered.
When a mommy and daddy decide they want to have a baby, they have what is known as "intercourse". This is when the daddy inserts his reproductive organs into the mommy's reproductive organs. When intercourse is done, the pregnant stage takes nine months, when those nine months are up, and the baby is ready, the laboring stage takes place. After a few hours of the laboring stage, viola, you have a baby.
