Upgrade 20x26x5 furnace filter Compatible with Lennox X8788 Filter (MERV 16) and PureAir PCO16-28 Air Cleaner. 1-Pack 20x26x5 Air Filter

Compatible Fit: For Lennox X8788 and PureAir PCO16-28 air cleaner systems that use 20 x 26 x 5 MERV 16 filters, so buyers can match by model and size before ordering | What Makes It Different: MERV 16 media in a ready-to-install replacement filter helps maintain the original compatible cabinet setup without buying a new air cleaner | Use Case: Made for scheduled whole-home HVAC filter changes when your existing X8788 or PCO16-28 filter label matches the listed model and size | Easy Install: Slide out the used filter, confirm the airflow arrow, and place the new 20 x 26 x 5 filter into the cabinet during routine maintenance | Maintenance Plan: Keep a spare filter on hand, inspect during seasonal service, and replace based on system run time, dust load, and indoor conditions
