1. Product Overview
The Filtrete 22x22x1 AC Furnace Air Filter, with a MERV 8 rating and MPR 700, is designed to enhance indoor air quality by capturing various airborne particles. This filter utilizes advanced electrostatic technology to attract and trap microscopic particles, contributing to a cleaner and fresher home environment.
It is effective against common household particles such as lint, pollen, dust, and pet dander. The filter's pleated design maximizes surface area for particle capture while maintaining optimal airflow through your heating and cooling system.

2. Setup and Installation
Proper installation of your Filtrete air filter is crucial for effective air filtration. Follow these steps to ensure correct placement in your furnace or air conditioning unit.
- Identify Filter Location: Locate the air filter slot in your furnace or air conditioning system. This is typically found in the return air duct or within the air handler unit itself.
- Remove Old Filter: Carefully slide out the old, dirty air filter. Note the direction of the airflow arrow on the old filter before removal.
- Unpack New Filter: Remove the new Filtrete filter from its plastic packaging.
- Orient Filter Correctly: Find the airflow arrow printed on the frame of the new Filtrete filter. This arrow must point in the direction of the airflow, towards the furnace or air handler unit.
- Insert New Filter: Slide the new filter into the slot, ensuring the airflow arrow is pointing correctly. Make sure the filter fits snugly without gaps around the edges.

3. Operating Instructions
Once installed, the Filtrete air filter operates continuously as part of your HVAC system. It works by trapping airborne particles as air passes through the filter media. For optimal performance, ensure your HVAC system is running as recommended by its manufacturer.
The electrostatic charge on the filter media enhances its ability to capture a wide range of particles, from larger lint and dust to microscopic allergens like pollen and pet dander.
4. Maintenance
Regular replacement of your air filter is essential for maintaining indoor air quality and the efficiency of your HVAC system. For 1-inch filters like this model, it is recommended to change the filter at least every 90 days.
Factors such as pets, allergies, construction, or high levels of outdoor pollution may necessitate more frequent filter changes.

5. Troubleshooting
If you experience issues after installing your Filtrete air filter, consider the following common troubleshooting steps:
- Reduced Airflow:
- Ensure the airflow arrow on the filter is pointing towards the furnace/air handler. Incorrect orientation can restrict airflow.
- Check if the filter is excessively dirty. A clogged filter will reduce airflow. Replace if necessary.
- Excessive Dust:
- Verify the filter size matches your unit's requirements to prevent air bypassing the filter.
- Confirm the filter is installed correctly with no gaps around the frame.
- Consider if the filter needs more frequent replacement due to environmental factors (e.g., pets, construction dust).
- Unusual Noises:
- Ensure the filter is securely seated in its slot and not vibrating.
- Check for any obstructions near the filter or in the ductwork.
If problems persist, consult a qualified HVAC technician.
