Changing your air filter is a crucial home maintenance task that ensures your indoor air quality is at its best. It’s an easy and affordable way to improve the health and comfort of your family while extending the life of your HVAC system. Follow our comprehensive guide to learn how to change an air filter in a few simple steps.

Tools and Materials Required

• New air filter (correct size for your system)
• Screwdriver (optional)
• Ladder (if necessary)

Safety Precautions

Before you start, turn off the power to your HVAC system at the circuit breaker or fuse box. This will prevent any electrical shocks or damage to your equipment.

How to Change an Air Filter

1. Locate Your Air Filter

The air filter is typically located in one of three places:

• Inside the return air vent on the wall or ceiling
• In a metal box or cabinet on the wall or ceiling
• Inside the air handler unit in your attic, basement, or utility closet

2. Remove the Old Filter

• Locate the access panel or door to the filter compartment.
• Carefully remove the old air filter by pulling it straight out.
• Inspect the old filter for any signs of dirt, dust, or debris.

3. Measure and Choose the Correct Filter

• Before purchasing a new filter, measure the dimensions of the old one.
• Choose a filter with the same size and thickness as the old one.
• Consider the MERV rating (Minimum Efficiency Reporting Value) of the filter. Higher MERV ratings indicate better filtration efficiency, but may also restrict airflow.

4. Install the New Filter

• Hold the new filter with the arrows pointing towards the direction of airflow.
• Insert the filter into the compartment and slide it into place.
• Ensure that the filter is snugly fit and there are no gaps around the edges.

5. Replace the Access Panel

• Close the access panel or door and secure it with screws if necessary.
• Turn the power back on to your HVAC system.

6. Reset Your Filter Reminder

• If your HVAC system has a filter reminder, reset it to indicate that a new filter has been installed.
• This will remind you to change the filter regularly.

Benefits of Changing Your Air Filter

• Improved indoor air quality: Removes dust, pollen, pet dander, and other allergens from the air.
• Reduced respiratory problems: Cleaner air can alleviate symptoms of asthma and allergies.
• Increased HVAC efficiency: A clean filter allows for better airflow, reducing strain on your system and lowering energy bills.
• Extended HVAC lifespan: Prevents dirt and debris from damaging your HVAC components.

How Often Should I Change My Air Filter?

The frequency of air filter changes depends on several factors:

• Season: Change your filter more often during allergy seasons and when heating or cooling your home heavily.
• Pets: If you have pets, change your filter more frequently to remove pet hair and dander.
• Home size and activity level: Larger homes and homes with more occupants generate more dust and require more frequent filter changes.
• Filter type: Higher-efficiency filters (MERV 11 or higher) should be changed more often than lower-efficiency filters.
