Given the threat of biological or chemical terrorism, it is natural to talk a lot about gas masks. Before deciding to buy and use a gas mask, it is important to understand the technology behind the different types of equipment available.
It is also important to understand that gas masks alone do not provide adequate protection against biological or chemical contamination. Even the use of protective clothing offers only a certain level of protection against airborne pollutants.

The only way to be fully protected was to wear a suit that completely covered the wearer and sealed off the air, which meant the use of SCBA gear was necessary.
The least effective type of gas mask is known as the air-purifying half-mask respirator. They cover the nose and mouth, allowing the wearer to breathe through the mask's filter system. However, many chemical and biological agents use the eye as an entry point and cause contamination.
A more effective type of mask is known as a full-face air-purifying respirator. This gas mask provides a clear face mask or goggles that protect the eyes as well as the nose and mouth.
