Ever wonder how your air conditioner creates cool, refreshing air?
Air filters are an important factor in the overall functionality of your A/C. Not only do they purify the air you breathe, but they also safeguard your system from potential damage.
In this article, we’ll discuss how air filters work and share practical tips for keeping your A/C performing at its best.
What Is an Air Filter?
An air conditioner filter is a flat, rectangular screen typically constructed from materials like cotton, fiberglass, cloth, or paper. These filters serve two primary purposes:
- They trap dust, dirt, pollen, and other airborne contaminants to reduce the likelihood of allergies and respiratory problems.
- Filters keep particles from entering and clog key internal components in your A/C, reducing strain on the system and helping it function more efficiently.
How Often Should You Replace Your Air Filter?
For the best air quality, we recommend you replace your air filter every 1 to 3 months.
If you notice a musty odor coming from your air conditioner, it could indicate the presence of mold or mildew in the system. If this is the case, check and replace the filter immediately.
How to Replace an Air Filter: Step-by-Step
Here’s a straightforward guide to help you replace your air filter:
Step 1: Power Down Your A/C
Before replacing the filter, make sure to turn off the air conditioning unit. This will prevent any accidental injury and stop dust from circulating into your home during the process.
Step 2: Locate the Air Filter
You’ll typically find the air filter in one of the following locations:
- Behind the return air vent or grille.
- Inside the HVAC system’s air handler unit.
- Behind the front cover of a window air conditioner.
Step 3: Remove the Used Filter
Open the filter compartment. This might involve unscrewing or unclipping the access panel, depending on your system.
Gently pull out the old filter, paying attention to the arrows that indicate airflow direction.
Step 4: Check the Filter Size
Be sure to note the dimensions printed on the filter’s edge to ensure you buy the correct size replacement.
Step 5: Install the New Filter
Insert the new filter, ensuring the arrows point in the correct direction—usually toward the blower and away from the return duct.
Make sure the filter fits securely in the compartment.
Step 6: Close the Access Panel
Reattach the panel or grille, using screws or clips if needed, to ensure it is securely in place.
Step 7: Turn the A/C Back On
Once the new filter is installed, restart your air conditioner and enjoy the clean, refreshing air.
