1. Determine the Filter Size and Type

Before you start, you’ll need to know the correct filter size and type for your HVAC system. The filter size is usually printed on the existing filter, but you can also find this information in your mobile home’s owner’s manual or by checking the HVAC system itself. Common filter sizes include 16×20 inches, 20×25 inches, and 16×25 inches, among others. Additionally, before changing your air filter choose the filter type that suits your needs, such as fiberglass, pleated, or HEPA filters.

2. Turn Off the HVAC System

To ensure your safety during the filter replacement process, turn off the HVAC system. Locate the thermostat and set it to the “off” position. This prevents the system from running while you are working on it.

3. Access the Air Filter Location

The air filter is typically located near the return air vent in your mobile home. This vent is usually positioned in a central area, such as a hallway or living room. You may need to remove a vent cover or access panel to reach the filter. Use a screwdriver or appropriate tool to open the vent or panel, exposing the old filter.

4. Remove the Old Filter

Carefully slide the old air filter out of its slot. Pay attention to the airflow direction indicated on the filter frame; this direction should be facing toward the HVAC system. If the filter is dirty or clogged, it’s time for a replacement.

5. Dispose of the Old Filter

Properly dispose of the old air filter. Fold it closed with the dirty side facing inward to contain any dust and contaminants. Seal it in a plastic bag before disposing of it in your household trash or following local recycling guidelines. Do not attempt to clean and reuse disposable filters, as this can reduce their efficiency.

6. Prepare the New Filter

Unwrap the new air filter and inspect it for any damage during shipping. Ensure that the airflow direction arrow on the filter frame is pointing toward the HVAC system, matching the direction of the old filter.

7. Install the New Filter

Carefully slide the new filter into the filter slot, aligning it with the arrows indicating the airflow direction. Make sure the filter fits snugly in the slot, with no gaps or spaces around the edges. Proper installation ensures that all air passing through the system flows through the filter.

8. Close the Vent or Access Panel

If you removed a vent cover or access panel to access the filter, replace it securely. Ensure that it is tightly fastened to prevent air leaks.

9. Turn on the HVAC System

Return to the thermostat and set it to the desired temperature. Turn on the HVAC system, and allow it to run for a few minutes to ensure that air is flowing properly through the new filter.

10. Establish a Filter Replacement Schedule

It’s essential to establish a regular filter replacement schedule based on your filter type and your mobile home’s specific needs. Standard fiberglass filters may need replacement every 30 to 60 days, while pleated or HEPA filters can last longer, often up to six months or more. However, it’s crucial to check the filter monthly, especially during peak HVAC usage seasons, and replace it when it appears dirty or clogged.

Properly changing your air filter in your mobile home is a straightforward yet crucial maintenance task that contributes to a healthier indoor environment, improved energy efficiency, and the longevity of your HVAC system. By following this step-by-step guide and adhering to a regular filter replacement schedule, you can ensure that your mobile home’s air remains clean, and your HVAC system operates at peak performance. This simple maintenance task goes a long way in promoting comfort and air quality in your mobile home.
