White-Rodgers FR1000M-111 Filters

For service professionals maintaining residential and light commercial forced-air systems, the White-Rodgers FR1000M-111 serves as a high-performance 16x20x4 media filter designed for the ACM1000M media air cleaner. This 3-pack of MERV 11 air filters is engineered to sustain a nominal 1000 CFM airflow, ensuring minimal static pressure drop while protecting the evaporator coil and blower motor from particulate accumulation. The electrostatically charged, 100% synthetic gradient media effectively captures airborne contaminants such as fine dust, pollen, mold spores, and pet dander without supporting microbiological growth. Built with a moisture-resistant, double-wall beverage board frame and a 30-gauge galvanized expanded metal support grid, these deep-pleat filters maintain structural integrity even in high-humidity environments up to 100% R.H. Replacing a 16x20x4 furnace filter with this high-efficiency media improves indoor air quality (IAQ) and optimizes the thermal transfer efficiency of the heat exchanger.

• Optimized Static Pressure: Rated for 1000 CFM, ensuring your blower motor doesn't work against excessive resistance common in lower-tier pleated filters.
• Technician-Grade Durability: Features a moisture-resistant frame and galvanized metal grid to prevent filter collapse or blow-by during high-static operation.
• Broad Compatibility: Direct replacement for the White-Rodgers FR1000M-111 and FR1000M-108, fitting seamlessly into ACM1000M enclosures.
• Advanced IAQ Protection: MERV 11 efficiency provides a significant upgrade over standard fiberglass, trapping over 90% of large-scale allergens.

• What are the actual dimensions of the FR1000M-111? Technical specifications list the actual size as 15.5" x 19.5" x 3.75" to ensure a proper seal within the 16x20x4 nominal housing.
• How often should these 4-inch filters be replaced? For optimal system performance and motor longevity, contractors recommend a change-out every 4 to 6 months depending on the environmental load.
• Will this filter fit other brands? Yes, if the air cleaner cabinet is designed for 16x20x4 media, this White-Rodgers replacement is cross-compatible with several whole-house systems.
