If inlet filters are dirty or moist, what should you do?

• A. Replace them
• B. Clean with water
• C. Leave as is
• D. Notify supervisor

Answer: (A)

When inlet filters are dirty or moist, the system’s airflow and filtration effectiveness are compromised. Replacing the filters is the correct action because new filters restore clean air pathways, maintain proper pressure and performance, and prevent contaminants from bypassing filtration. Cleaning a filter with water can damage the media, leave residues, and promote mold or bacterial growth in a moist environment, which can worsen contamination and degrade performance. Leaving the filters in place allows reduced efficiency, overheating, or contamination risks to continue. Notifying a supervisor or maintenance team is a good step if policy requires it or if you’re unsure about the replacement procedure, but the immediate, best action is to replace the filters.
