At what flow rate are Air-O-Cell cassettes typically used for sampling?

Air-O-Cell cassettes are designed for air sampling to detect mold spores and other biological particles. They are typically utilized at a flow rate of 15 liters per minute. This flow rate is optimal for ensuring that a representative sample of the air is collected over a set period. At this flow rate, the cassettes maintain their efficiency in capturing airborne particles while minimizing the potential for loss of smaller spores or fragments due to high velocity or turbulence caused by excessive flow rates. The use of this specific flow rate also aligns with standard practices in environmental sampling to achieve reliable and consistent results, which is critical for accurate assessment of airborne mold levels.

When using flow rates outside this optimal range, there may be issues with either insufficient collection of particles or potential damage to the sampling medium itself, leading to compromised data integrity.
