How to Change a Home Air Filter

Maintaining a clean and healthy home environment is essential for the well-being of you and your family. One often overlooked aspect of this process is changing your home’s air filter regularly. Air filters help to remove dust, pollen, and other airborne particles, ensuring that the air circulating inside your home is clean. In this article, we will provide you with a step-by-step guide on how to change your home air filter.
Step 1: Determine Your Air Filter Size
The first step in changing your home air filter is to determine its size. You can find this information on the side of the existing filter or in your HVAC unit’s user manual. Common sizes include 16×20, 20×25, and 16×25 inches. Make sure to note the measurements for reference when purchasing a new filter.
Step 2: Purchase a New Air Filter
Once you have determined the size of your air filter, you can visit your local hardware store or order one online. Choose between disposable and reusable filters according to your preference. Disposable filters should be replaced every 1-3 months, while reusable filters can be cleaned and re-installed.
Step 3: Turn Off Your HVAC System
Before removing the old air filter, it’s crucial to turn off your HVAC system for safety purposes. To turn off the system, locate the switch on the side of the unit or use the thermostat’s control panel.
Step 4: Locate and Remove the Old Air Filter
Locate your air filter within the HVAC system by referring to the user’s manual if needed. Filters are commonly found behind a vent grille or on top of an indoor unit. Carefully remove the old air filter while making sure not to spill any accumulated debris onto surrounding surfaces.
Step 5: Inspect and Clean Your HVAC Unit
With the air filter removed, take the opportunity to inspect your HVAC unit for any buildup of dust, dirt, or debris. Use a vacuum cleaner or soft cloth to gently clean any visible dirt. Regular cleaning can help maintain the efficiency and longevity of your unit.
Step 6: Insert the New Air Filter
Now that your HVAC unit is clean, insert the new air filter into its designated slot. Ensure that the airflow arrows on the filter’s frame match the direction indicated on the unit. Proper placement is crucial for maintaining optimal air circulation and filtration.
Step 7: Secure the Filter and Turn On Your HVAC System
After installing the new air filter, secure it in place by closing any latches or panels. Once everything is in place, turn your HVAC system back on using either the unit’s switch or thermostat control panel.
Step 8: Make a Reminder
To keep your indoor air clean and healthy, set a reminder on your phone or write it down on your calendar to change or clean your air filter every 1-3 months (for disposable filters) or as recommended by the manufacturer for reusable filters.
By following these simple steps, you can easily change your home’s air filter and enjoy cleaner, fresher air throughout your living space. With regular maintenance and timely filter replacements, you’ll contribute to a healthier home environment and extend the lifespan of your HVAC system.
