The air shower is a particularly enclosed outer chamber that works in conjunction with other controlled environments to prevent particle contamination. To remove dust and fibre lint containments from personal or object surfaces, an air shower uses high-pressure, HEPA or ULPA filtered air.

A device that prevents air or contaminants from travelling from one open space to another is known as an air curtain. A downward-facing blower fan installed over a building entrance or an aperture between two spaces conditioned at different temperatures is the most common application.
