Mold Remediation Certification Practice Exam

In mold remediation, what is the purpose of an air filtration device (AFD)?

1. To eliminate sources of water

2. To filter airborne contaminants

3. To regulate temperature

4. To contain mold spores

The correct answer is: To filter airborne contaminants

In mold remediation, the primary purpose of an air filtration device (AFD) is to filter airborne contaminants. During the remediation process, mold spores can become airborne, posing health risks to occupants and workers. The AFD is specifically designed to capture these spores, along with other particulate contaminants, thereby improving air quality in the remediation area. Using high-efficiency particulate air (HEPA) filters, AFDs can effectively trap even the smallest mold spores, preventing them from spreading throughout the environment. This function is crucial because controlling airborne mold particles is a key step in ensuring that the mold remediation process is successful and doesn’t inadvertently create a larger problem by dispersing spores into previously unaffected areas. The other options, while important in the context of mold remediation, do not directly relate to the function of an AFD. For instance, eliminating sources of water is vital for preventing future mold growth but is not the role of an air filtration device. Similarly, regulating temperature can aid in creating an inhospitable environment for mold but is not accomplished through filtration. Containing mold spores is part of the overall strategy during remediation, involving physical containment measures, whereas AFDs focus specifically on cleaning the air by filtering contaminants.
