Lennox X0581 Filter

The Lennox X0581 is a genuine OEM replacement filter designed for the Healthy Climate BMAC-12 (Boxed Media Air Cleaner) series. As a veteran technician, I recommend this MERV 11 secondary filtration media to maintain system static pressure while effectively capturing sub-micron particles. With nominal dimensions of 16"x25"x3", this pleated synthetic media provides a significant surface area for high dust-holding capacity without the rapid pressure drop associated with lower-quality "big box" filters. The electrostatically charged fibers are engineered to trap indoor air quality contaminants like pollen, mold spores, and pet dander down to 0.3 microns.

For contractors servicing Lennox residential systems, verify your actual clearance; the Lennox X0581 filter has an actual size of 15-7/8" x 24-1/4" x 3". It is the direct replacement for older Lennox BMAC units and cross-references with certain Trion Air Bear 101 models. Maintaining a clean 16x25x3 media is critical for protecting the evaporator coil and ensuring the blower motor operates within its designed HVAC system performance curve.

• MERV 11 High-Efficiency: Captures up to 85% of particles sized 3.0 to 10.0 microns, protecting high-efficiency heat exchangers.
• Optimized Static Pressure: Deep-pleat design ensures maximum airflow, reducing energy consumption and equipment wear.
• OEM Compatibility: Exact fit for Lennox BMAC-12C housings, preventing air bypass and ensuring all return air is filtered.
• Synthetic Media: Moisture-resistant material prevents microbial growth, keeping the air stream clean.

What is the actual size of the Lennox X0581?
The nominal size is 16x25x3, but the precise actual dimensions are 15-7/8" x 24-1/4" x 3". Always measure your existing frame before ordering.

How often should I change the MERV 11 X0581 filter?
Under standard residential load, this media should be replaced every 6 to 12 months. However, in homes with high pet dander or construction dust, check for loading every 90 days to prevent high static pressure.

Can this filter replace a MERV 10 version?
Yes, the X0581 is the updated MERV 11 version of the previous 16x25x3 MERV 10 media, offering improved airborne contaminant removal with minimal impact on airflow.
