Aerostar Series 1100 Furnace Air Filter 16x25x5 MERV 11 Trion & Air Bear Replacement

The Aerostar Series 1100 pleated furnace air filter delivers dependable MERV 11 filtration for residential, commercial, and industrial HVAC systems. Designed as a replacement for compatible Trion Air Bear systems, this 16x25x5 filter features advanced 100% synthetic media that captures dust, pollen, mold spores, pet dander, and other airborne particles while maintaining efficient airflow.

The synthetic media is laminated to an expanded metal support grid on the air-exiting side, preventing pleat fluttering and maintaining consistent pleat structure for reliable performance. A heavy-duty, moisture-resistant frame helps prevent warping, cracking, and distortion, while the bonded filter pack reduces air bypass and improves overall filtration efficiency.

Compatible with Trion Air Bear 255649-105 replacement applications, the Aerostar Series 1100 MERV 11 filter features rigid construction, deep pleats, and low initial pressure drop to provide longer service life and consistent performance. Ideal for homes, offices, schools, commercial buildings, and industrial facilities requiring improved indoor air quality and HVAC protection.
