What is the required flow rate through an Air-O-Cell cassette?

15 cfm
15 l/min
28.3 cfn
28.3 l/min

The correct answer is: 15 l/min

The required flow rate through an Air-O-Cell cassette is specified as 15 liters per minute (l/min) because this flow rate is optimal for capturing airborne particles effectively for analysis. The design of the Air-O-Cell cassette takes this flow rate into account to ensure that sufficient air passes through the sampling medium without causing turbulence that might disrupt the collection of particulate matter. The choice of liters per minute aligns with common units used in air sampling methodologies, particularly in indoor air quality assessments. This measurement allows for consistency in protocols and makes it easier to compare results across different studies and applications. In contrast, the other options present flow rates in cubic feet or alternative measures that are either not applicable in this context or do not meet the specific requirements for proper sampling with the Air-O-Cell device.
