Introducing the AAF Flanders PREpleat M11 SC 20 in. W x 24 in. H x 2 in. Synthetic 11 MERV Pleated Air Filter. Built for dependable performance in residential HVAC and light commercial environments, this filter blends advanced synthetic media with a sturdy frame to deliver consistent filtration at mask-free airflow levels.
Why this filter stands out
-
11 MERV filtration: Efficiently traps dust, lint, pollen, mold spores, and more, while still allowing good airflow for smooth furnace and air handler operation.
-
Electrostatic media: Charged fibers attract and capture fine particles, helping reduce airborne irritants that trigger allergies and sensitivities.
-
PREpleat design: Optimized pleat arrangement increases surface area for extended service life between changes, translating to fewer filter replacements.
-
Synthetic filtration media: High-capacity particle capture with durable performance across a range of indoor environments.
-
Beverage board frame with metal mesh support: Rigid construction resists sagging and maintains pleat integrity for a tight, consistent seal in the filter housing.
-
Class II rated: Suitable for general ventilation needs, balancing filtration efficiency with system compatibility.
-
Non-trimmable, exact fit: Designed for 20x24x2 nominal slots, with an actual size of 19-3/8 x 23-3/8 x 1-3/4 to confirm fit in your equipment.
-
Filters bacteria, pollen, smoke, and some viruses: Helps improve indoor air quality in homes and small offices where particulates and volatile contaminants are a concern.
Ideal for who and where
This filter is a strong choice for households dealing with seasonal allergies, pet dander, or smoke exposure, as well as spaces like apartments, small offices, and mixed-use environments that rely on reliable HVAC filtration. If you want a balance of strong pollutant control and compatible airflow in a 20x24x2 system, the PREpleat M11 SC is engineered to meet those needs.
Practical fit and use tips
- Confirm nominal vs actual size before installation: nominal 20x24x2, actual 19-3/8 x 23-3/8 x 1-3/4.
- Install in the airflow direction indicated by your HVAC unit to maximize filter efficiency.
- Replace when you notice a drop in airflow or increased dust buildup beyond routine cleaning—this typically aligns with your system’s maintenance schedule.
- Since it’s non-trimmable, ensure your filter slot is compatible with the 20x24x2 nominal frame for a proper seal.
