White-Rodgers FR1600M-111 Filter

The White-Rodgers FR1600M-111 is a high-performance 20x20x4 furnace filter engineered for media air cleaners requiring a nominal flow of 1600 CFM. This 3-pack of MERV 11 replacement filters provides an exact fit for the Emerson ACM1600M whole-house air cleaner series, as well as several TopTech models. With a deep-pleat design, these filters offer a significantly higher surface area compared to standard 1-inch filters, resulting in a low pressure drop and extended service life for the heat exchanger and blower motor. The MERV 11 rating ensures the capture of particles as small as 1 to 10 microns, including fine dust, pollen, and pet dander, without sacrificing the system's static pressure balance. For contractors, the durable, box-formed construction means no assembly or combs are required on-site, allowing for rapid HVAC filter replacement during routine maintenance cycles.

• Direct OEM Compatibility: Specifically designed to replace White-Rodgers FR1600M-111 and FR1600M-108 media without system modifications.
• High-Efficiency Filtration: The MERV 11 media captures up to 85% of particles sized 3.0 to 10.0 microns, protecting high-efficiency coils from dust loading.
• Optimized Airflow: Rated for systems up to 1600 CFM, maintaining the necessary velocity for consistent cooling and heating cycles.
• Professional Grade 3-Pack: Sized for residential and light commercial whole house air filters, ensuring enough stock for a full year of maintenance.

What is the actual size of the FR1600M-111?
While the nominal size is 20x20x4, the actual dimensions are approximately 19-3/8" x 19-3/8" x 3-5/8". Always verify the cabinet clearance before installation.

Can I use this in a TopTech air cleaner?
Yes, this filter is a verified cross-reference for the TopTech TT-FM-2020 and provides identical filtration performance and fitment.

How often should these MERV 11 filters be changed?
In standard residential applications, these deep-pleat filters typically require replacement every 6 to 9 months, though high-occupancy or pet-friendly environments may require more frequent HVAC maintenance.
