Maintaining Your Air Unit: A Guide to Prolonging its Lifespan


Your air filtration unit plays a crucial role in maintaining clean and healthy indoor air. To ensure it operates efficiently and serves you well for years, it's essential to perform regular maintenance. In this blog post, we'll discuss key maintenance tasks, including changing out your filters, periodically wiping out the unit, and checking the belt drive, all while keeping an eye on your indoor air quality.

Changing Out Your Filters

Regularly changing your air filters is one of the most important maintenance tasks for your air filtration unit. Air filters serve as the first line of defense against airborne pollutants, capturing dust, pollen, pet dander, and other contaminants. When filters become clogged, airflow is restricted, making the unit work harder and potentially reducing its effectiveness. Here's what you should know about filter maintenance:

1. Frequency: The frequency of filter replacement depends on the type of filter and your usage. In most residential settings, it's recommended to change filters every 1 to 3 months. In high-traffic commercial environments or homes with pets, consider more frequent replacements.

2. Filter Type: Choose the appropriate filter for your needs. Different MERV ratings and materials are available to capture specific particle sizes and contaminants. Refer to the manufacturer's recommendations for your unit.

3. Inspect for Damage: Before installing a new filter, inspect the filter compartment for any damage or debris that may have entered the unit.

Periodically Wiping Out the Unit

In addition to changing the filters, you should periodically clean the interior of your air filtration unit. Over time, dust and particles can accumulate within the unit, reducing its efficiency and potentially causing damage. Here's how to perform this essential maintenance task:

1. Turn Off the Unit: Before cleaning, always turn off the air filtration unit and unplug it from the power source.

2. Open the Unit: Remove the access panel or grille, following the manufacturer's instructions. Inside, you may find dust and debris accumulated on the interior surfaces and components.

3. Wipe Clean: Use a soft, damp cloth or a vacuum cleaner with a brush attachment to gently remove the accumulated dust. Pay close attention to the blower wheel, the motor, and any electronic components.

4. Check for Mold: If you notice any signs of mold growth, it's crucial to address it promptly. Mold can negatively impact indoor air quality. Consult a professional for mold remediation if necessary.

5. Reassemble the Unit: Once the interior is clean and dry, reassemble the unit and ensure a tight seal.

Checking the Belt Drive

Many air filtration units use a belt-driven system to operate the blower. A properly functioning belt drive is essential for optimal performance. Here's how to inspect and maintain the belt drive:

1. Access the Belt: To access the belt, remove the access panel or grille as you did when cleaning the interior.

2. Check for Wear: Inspect the belt for signs of wear, such as cracks or fraying. If you notice any issues, it's time to replace the belt.

3. Tension Adjustment: Check the tension of the belt. It should have some give but not be overly loose. If it's too loose, consult the unit's manual for instructions on how to adjust the tension properly.

4. Lubrication (if applicable): Some units may require periodic lubrication of bearings. Consult your user manual for guidance on lubrication intervals and types of lubricants to use.

5. Reassemble and Test: After maintenance, reassemble the unit and ensure the belt is properly aligned. Turn the unit on and check for any unusual sounds or vibrations, which may indicate a problem with the belt drive.


Maintaining your air filtration unit is essential to ensure that it continues to provide clean and healthy indoor air. Regularly changing out your filters, periodically wiping out the unit, and checking the belt drive are all critical tasks in this process. By following these maintenance guidelines, you can prolong the lifespan of your air filtration unit and enjoy the benefits of improved indoor air quality for years to come. Remember that your specific unit's maintenance requirements may vary, so always consult the manufacturer's instructions and recommendations for the best results.
