Abstract
A system for checking interior air contamination, the system including a sealed device including twin ports, a sampling device including a pump to extract at least some of the air from the interior of the sealed device, and a microbial detect to determine if the air contains contaminants. The twin ports are removably engageable with the sampling device to allow a circuit of air between the pump unit and the sealed device, such that air extracted from one of the twin ports by the pump is returned to the other of the twin ports, allowing no escape of the air to the environment. The sealed device is sealed to prevent, except through the twin ports, exterior air to flow into the sealed device and the air from the interior to flow out.
