Air filtration is the process of removing particles, contaminants, and pollutants from the air using physical, chemical, or biological methods. In the environmental context, air filtration plays a crucial role in improving air quality by reducing harmful substances such as dust, pollen, smoke, bacteria, and volatile organic compounds (VOCs) from both indoor and outdoor environments. Effective air filtration is essential for protecting human health, preserving ecosystems, and mitigating the impacts of air pollution.

An Air Gap is Open vertical gap or empty space that separates drinking water supply to be protected from another water system in a treatment plant or other location.

An Air Handling Unit is Equipment that includes a fan or blower, heating and/or Cooling coils, regulator controls, Condensate drain pans, and air filters.

An Air Heat exchange is a Cooling method, involving no water loss, during which a fan blows air past finned tubes carrying recirculating Cooling water (Brown and Caldwell, 1990).

An Air Mass is a large volume of air with certain meteorological or polluted characteristics e.g., a Heat inversion or smogginess--while in one location.

An Air Monitoring is (See: monitoring.

An Air Padding is Pumping dry air into a Container to assist with the withdrawal of liquid or to force a liquefied gas such as chlorine out of the container.

An Air Passages is Openings through or within walls, through floors and ceilings, and around chimney flues and plumbing chases, that permit air to move out of the conditioned spaces of the building.

An Air Permeability is Permeability of soil with respect to air. Important to the design of soil-gas surveys. Measured in darcys or centimeters-per-second.

An Air Plenum is any space used to convey air in a building, furnace, or structure. The space above a suspended ceiling is often used as an Air Plenum.
