Lennox X1152 Media Filter

The Lennox X1152 Air Bear Media Filter is a high-performance 20x25x5 MERV 11 filtration solution designed for intensive residential and light commercial HVAC applications. Also identified as part number X115201, this pleated media cartridge is a direct replacement for Trion Air Bear and Healthy Climate systems. Engineered with a double-walled beverage board frame, it maintains structural integrity under 2000 CFM airflow, preventing bypass and ensuring all air passes through the 100% synthetic, electrostatically charged media. By capturing particles as small as 0.3 microns, including fine dust, pollen, and pet dander, the Lennox X1152 protects the evaporator coil from fouling, which maintains system static pressure and optimizes heat transfer efficiency. Technicians should note the actual dimensions of 19-3/4" x 24-1/4" x 4-7/8" to ensure a precise fit in the filter rack, as non-standard housings may lead to air leakage.

Key Benefits

• High Dust-Holding Capacity: Advanced pleated media geometry increases surface area, extending the service interval between 6 to 12 months depending on environmental load.
• Universal Component Compatibility: Effectively replaces Honeywell F100F1012, Trion 255649-102, and Air Bear Supreme 2000 cartridges.
• Optimized HVAC Performance: Deep-loading MERV 11 design balances high-efficiency indoor air quality with low pressure drop to reduce blower motor strain.
• Rigid Construction: The beverage board frame and double-walled casing resist moisture and collapse, even in high-humidity return air streams.

Common Questions

Is the Lennox X1152 compatible with other 20x25x5 systems?
Yes, the Lennox X1152 is a standard-sized 5-inch media filter that fits most Air Bear, Honeywell, and Healthy Climate cabinets requiring a nominal 20x25x5 insert. Always verify the actual dimensions against your existing housing.

What is the difference between X1152 and X115201?
There is no functional or technical difference; X1152 and X115201 are identical parts used by Lennox for the same MERV 11 air filter specification.

How often should a MERV 11 media filter be replaced?
For peak HVAC system efficiency, replacement is recommended every 6 to 12 months. In high-traffic environments or homes with multiple pets, more frequent changes may be required to prevent increased static pressure.
