3. Setup and Installation
Proper installation of your Filtrete air filter is crucial for effective air filtration and optimal HVAC system performance. Always ensure the filter is correctly sized for your unit before installation.
Installation Steps:
- Remove any plastic wrap and the label from the new filter. Do not remove the cardboard frame.
- Locate the designated opening in your home furnace or air conditioning system where the filter is inserted.
- Insert the new filter into the frame, ensuring the arrow on the filter frame points TOWARD THE BLOWER MOTOR. This indicates the direction of airflow.
- Secure the filter in place and close any access panels.

4. Operating Principles
Filtrete air filters operate using an electrostatically charged media that acts like tiny magnets to attract and capture microscopic particles from the air as it passes through the filter. This 3-in-1 technology ensures a balance between particle capture and maintaining adequate airflow for your HVAC system.

5. Maintenance
For optimal performance of your heating and cooling system, it is recommended to change your 1-inch air filter at least every 90 days. Certain conditions in your home, such as pets, construction work, or tobacco smoke, may necessitate more frequent filter changes to maintain air quality and system efficiency.
Setting Filter Change Reminders:
To help you remember when to change your filter, you can use the Filtrete Smart App (available for iOS and Android devices). The app allows you to scan the filter's barcode and set personalized 30-, 60-, or 90-day reminders.

6. Troubleshooting
If you experience reduced airflow or unusual noises from your HVAC system after changing the filter, ensure the filter is installed correctly with the airflow arrow pointing towards the blower motor. Verify that the filter size matches your unit's requirements. A filter that is too restrictive (higher MERV rating than recommended by your HVAC manufacturer) can also cause airflow issues and strain your system. Consult your HVAC system's manual or a professional technician if problems persist.
