Aerostar Series 1100 Pleated Furnace Air Filter 16x25x5 MERV 11 Honeywell Lennox Replacement

The Aerostar Series 1100 pleated furnace air filter is designed to provide high-efficiency filtration while maintaining reliable airflow through your HVAC system. Featuring advanced 100% synthetic filter media, this MERV 11 filter captures fine airborne particles such as dust, pollen, mold spores, pet dander, and other allergens to help improve indoor air quality.

Engineered for consistent performance and long service life, the Series 1100 design provides increased dust-holding capacity while reducing airflow restriction. The expanded metal support grid helps prevent pleat fluttering and maintains pleat uniformity, while the durable moisture-resistant frame provides strength and prevents air bypass for dependable filtration.

Designed as a replacement filter for Honeywell FC100A1003 and compatible Lennox HVAC systems, this 16x25x5 MERV 11 furnace filter is ideal for residential, commercial, and industrial applications. It helps protect coils, ductwork, and HVAC components while providing enhanced filtration performance. Replace regularly based on usage conditions and indoor air quality needs.
