Fine liquid or solid particles suspended in air. For example Fog or Smoke. They can be microscopic and less than 1 micron in size. They can chemical or biological and composed of many parts.

The number of times per hour the room air volume will pass through the air cleaner or air purifier. A typical air change rate for a well selected HEPA system would be about 5 Air Changes per hour. ACR can be calculated by dividing the Air Volume Flow Rate M3/hr of the air cleaning unit by the volume of the room in M3.

The Camfil air purifier uses typically uses HEPA class filtration to remove ultra-fine airborne particles from the air in a room but also has molecular filtration to remove odours and selected noxious gases and fully clean the air. It would be used in office, light industrial and residential applications. Camfil City M 300 and 800 Models are of thi [..]

The Air Volume Flow Rate for an Air Cleaner is usually given in Metres3/Hour although Cubic Feet per minute CFM is sometimes used for older unit measurements or units manufactured in the USA.
