How to Install a Filter in an AHU (Air Handling Unit)

Installing a filter in an Air Handling Unit (AHU) is a crucial step to ensure clean airflow, improve indoor air quality, and protect internal components from dust and debris. Filters trap airborne particles, preventing them from circulating through the HVAC system.

Steps to Install a Filter in an AHU:

1. Turn Off the Unit:
   Always begin by switching off the AHU to ensure safety during maintenance.

2. Access the Filter Section:
   Open the access panel or door to the filter compartment. This area is usually clearly marked on the AHU.

3. Remove the Old Filter:
   Carefully slide out the used filter. Note the size and airflow direction indicated on the frame, which will guide the installation of the new filter.

4. Clean the Filter Housing (If Needed):
   Use a vacuum or a damp cloth to remove any dust or debris from the filter slot or frame.

5. Install the New Filter:
   Insert the new filter in the correct orientation, ensuring the airflow arrow points in the direction of air movement—typically toward the fan section.

6. Close the Access Panel:
   Once the filter is securely in place, close and latch the access panel properly.

7. Turn On the AHU:
   Power up the unit and check for normal operation.

Important Tips:

• Use the correct filter type and size as specified by the manufacturer.

• Replace filters regularly, depending on usage and environment (typically every 1–3 months).

• For high-efficiency systems, HEPA or MERV-rated filters may be required.

Proper filter installation helps maintain optimal airflow, system efficiency, and healthy indoor air conditions.
