1. Introduction
The Lennox X6675 Carbon Clean MERV 16 Air Filter is designed to enhance indoor air quality by filtering airborne particles and reducing odors. This filter combines MERV 16 filtration efficiency with a carbon-coated fiber matrix, providing advanced air purification for compatible HVAC systems. It is engineered to capture a high percentage of microscopic particles, including those as small as 0.1 microns.
2. Safety Information
- Always turn off your HVAC system's power at the thermostat and circuit breaker before attempting to replace the air filter.
- Wear appropriate personal protective equipment, such as gloves, to avoid contact with dust and debris accumulated on the old filter.
- Handle the new filter carefully to prevent damage to the filter media.
- Dispose of used filters according to local waste disposal guidelines.
3. Setup and Installation
Follow these steps to replace your air filter:
- Locate the filter housing in your HVAC system. This is typically found in the return air duct or within the air handler unit.
- Open the filter access panel or door. Some systems may require unscrewing latches or clips.
- Carefully slide out the old filter. Note the direction of the airflow arrow printed on the filter frame.
- Unpack the new Lennox X6675 filter. Ensure the airflow arrow on the new filter points in the same direction as the old filter, typically towards the furnace or air handler.
- Slide the new filter into the housing until it is fully seated. Ensure there are no gaps around the filter that could allow air to bypass it.
- Close and secure the filter access panel or door.
- Restore power to your HVAC system.

5. Maintenance
Regular inspection and timely replacement of your air filter are crucial for maintaining system efficiency and indoor air quality.
Filter Replacement Schedule:
- The Lennox X6675 filter is designed to last up to 1 year in many home environments.
- However, actual lifespan can vary based on factors such as pet ownership, presence of allergies, local air quality, and HVAC system usage.
- Inspect the filter monthly. If it appears heavily soiled or airflow is noticeably reduced, replace it sooner.
Disposal:
Used air filters contain accumulated dust and particles. Place the old filter in a sealed plastic bag before disposing of it in your household waste to prevent the release of captured contaminants.
6. Troubleshooting
Reduced Airflow:
- Issue: HVAC system seems to be working harder, or air coming from vents is weaker than usual.
- Solution: Check the filter for excessive dirt and debris. A clogged filter restricts airflow. Replace the filter if it is heavily soiled. Ensure the filter is installed with the airflow arrow pointing in the correct direction.
Filter Does Not Fit:
- Issue: The new filter is too large or too small for the filter housing.
- Solution: Verify the dimensions of your filter housing and compare them with the actual filter dimensions (19.93" x 24.68" x 4.31"). Ensure you have the correct model number (X6675) for your system.
