3. Installation Instructions
Follow these steps to safely replace your air filter. If you are unsure about any step, consult a qualified HVAC technician.
- Power Off: Before beginning, turn off the power to your HVAC system at the thermostat and the main power switch (usually located near the furnace or air handler). This is a critical safety step.
- Locate Filter Slot: Identify the filter slot or housing in your PCO20-28 PureAir unit. This is typically located in the return air duct or within the furnace/air handler cabinet.
- Remove Old Filter: Carefully slide out the old filter. Note the direction of the airflow arrow on the old filter.
- Inspect Unit: While the filter is out, you may gently wipe away any visible dust or debris from the filter housing area.
- Orient New Filter: Unpack the new Lennox X8788 filter. Locate the airflow arrow printed on the filter frame. This arrow must point in the direction of the airflow towards the furnace/air handler.
- Insert New Filter: Slide the new filter into the housing, ensuring the airflow arrow is correctly oriented. Make sure the filter fits snugly without gaps around the edges, which could allow air to bypass the filter.
- Restore Power: Once the new filter is securely in place, close the filter housing door (if applicable) and restore power to your HVAC system.
- Record Date: Write the installation date on the filter frame for future reference.

4. Operation and Function
The Lennox X8788 filter operates passively as part of your HVAC system. When your furnace or air conditioner runs, air is drawn through the filter, where airborne particles are trapped by the MERV 16 pleated media. This process cleans the air before it is circulated back into your living space.
No user interaction is required for the filter's operation beyond proper installation and timely replacement.
5. Maintenance
Regular replacement of your air filter is the primary maintenance requirement to ensure optimal performance of your PureAir system and maintain indoor air quality.
- Replacement Schedule: The Lennox X8788 filter is designed for replacement every 12 months under typical residential use.
- Inspection: Periodically inspect the filter (e.g., every 3-6 months) to check for excessive dirt buildup. In environments with high dust, pets, or during heavy HVAC usage, more frequent replacement may be necessary.
- Disposal: Dispose of the old filter according to local waste disposal guidelines.
Failure to replace the filter as recommended can lead to reduced airflow, decreased system efficiency, increased energy consumption, and potential damage to your HVAC equipment.
6. Troubleshooting
Most issues related to air filters are resolved by proper installation and timely replacement.
| Problem | Possible Cause | Solution |
