EXACT FIT REPLACEMENT: Designed as a direct replacement for Lennox X8789 air filters. Nominal Size: 16" x 26" x 5" | Actual Size: 16-3/8" x 25-1/2" x 4-3/8". Compatible with Lennox PureAir PCO16-28 air cleaner systems and other units that use the same filter size. Please verify your current filter dimensions before ordering to ensure proper fit.
SUPERIOR MERV 16 RATED EFFICIENCY: Upgrade your home’s air quality with high-efficiency MERV 16 filtration. The premium white pleated media helps capture common airborne particles such as dust, pollen, and pet dander as air circulates through your HVAC system, helping maintain cleaner indoor air throughout your home.
PROTECTS YOUR HVAC SYSTEM: A high-quality filter helps keep your system running efficiently by reducing airborne dust buildup on internal components (like coils and blowers). Maintaining a clean, unclogged filter also helps protect airflow and overall HVAC performance, reducing strain that can contribute to premature wear.
DURABLE FRAME CONSTRUCTION: Built with a sturdy frame and reinforced pleats to maintain shape under airflow. A secure fit helps minimize “air bypass” (unfiltered air leaking around the edges), supporting consistent filtration performance.
LONG-LASTING & EASY INSTALLATION: Estimated service life is up to 12 months in many home environments (actual replacement timing depends on factors like pets, occupancy, and HVAC usage). Installation is tool-free and takes seconds: simply slide out the old media and slide in the new X8789 replacement filter.
Long-distance shipping can sometimes be tough on packages. If your filter arrives damaged or dented in any way, just reach out to our customer service team right away—we'll send you a brand new replacement at no cost, no return needed. We're here 24/7 to make things right, because your satisfaction is what truly matters to us.
