The PREpleat M11 SC pleated panel filter enables a significant upgrade in collection efficiency over existing MERV 8 products. A 25–30% average efficiency filter can be upgraded to 60–65% efficiency at roughly the same resistance levels, when this filter is utilized.
Superior Design and Construction
Media: Progressive density bi-component fibers. Airflow Resistance on 24" x 24" x 2": 0.34" w.g. @ 2000 CFM (500 FPM).
Media Support: Diamond-shaped expanded metal. Pleat Design: V-Pleat design aids in pressure drop while reducing energy cost. Design allows for maximum airflow and Dust Holding Capacity (DHC) during the life of the filter.
Frame: Moisture-resistant clay coated frame.
Bi-Component Media: Ultra-high performance bi-component synthetic media contains electrostatically engineered trilobal fibers within homogenous domains of positive and negative Electret charges. These Electret charges in the bi-component fibers contribute to an ultra-high performance product.
Enhanced Fibers: Electrostatically enhanced fibers are precisely structured into a progressive density gradient structure to enhance airflow throughput with less resistance while providing high DHC and ultra-high efficiency during operational life.
Gradient Media Structure: Proprietary gradient media structure enables larger incoming contaminants to be trapped in the prefilter layer, thus allowing the highly charged secondary layer to attract and hold smaller particulate. This increases the life of more expensive final filters downstream.
High Efficiency at Low Pressure Drop: This proprietary media, combined with AAF Flanders unique V-Pleat manufacturing design, equals the highest performance pleat available on the market today.
PREpleat M11 SC filters are designed for general air filtration in all types of cooling, heating, and ventilating systems. They can be used as prefilters to extend the life of higher efficiency filters or on their own. They are suitable for installation in front access holding frames and side access housings. These filters are excellent for upgrading from disposable panel filters, permanent filters, or media pads in metal frames where a higher level of cleaning is desired.
- 2x-3x higher efficiency on small particles than standard MERV 8 pleated filters
- Increases life of downstream filters
- Significantly improved protection against bioaerosols and other hazardous particles
- Reinforced with corrosion-resistant heavy metal backing
- 2-piece die cut double-wall frame with diagonal face strips for extra strength
- Nominal Size: 20 x 20 x 2
- Actual Size: 19-1/2 x 19-1/2 x 1-3/4
- Quantity: 12 Filters
- MERV 11 Rating
MERV Rating: MERV 11
Nominal Size: 20x20x2
Actual Size: 19-1/2 x 19-1/2 x 1-3/4
Media: 100% synthetic non-woven, proprietary media that can be recycled. Engineered with a gradient density composition that achieves it's MERV rating using the mechanical method of particle capture. Media does not rely on an electrostatic charge to capture particulate, since electrostatic charged filters dissipate over time.
Frame: Heavy-duty, two piece, moisture-resistant frame with diagonal support members. Frame is bonded to the media at all points of contact for unsurpassed frame strength. Interlocking corners and positive media-to-frame seal reduce the possibility of air bypass.
Support Grid: Expanded metal is continuously laminated on the air leaving side to provide pleat stability during operation. Pleat shape is maintained allowing full media utilization which improves dust holding capacity.
Replace: Recommended 90 day changeout
Removes: MERV 11 rating reduces up to 90% of airborne particles as small as 1 micron including dust and lint, dust mite debris, pollen, pet dander, mold spores, bacteria, virus carriers, as well as most smoke and smog.

Perfectly Compatible with HVAC, AC, and Furnace Systems
Ever wondered about the difference between a 'furnace filter' and an 'air conditioner (AC) filter'? Are they two separate filters for your home's heating, ventilation, and air conditioning (HVAC) system, or is it just a single filter serving both functions? The answer is simple—they are indeed the same! The terminology often varies based on geographical location, but rest assured, they refer to the same essential component of your HVAC system.
High-Quality Filters Crafted by Reputable Manufacturers
As an authorized retailer of renowned brands like AAF Flanders, NaturalAire, Exact Filters, EZ Flow, and more, we provide effective filtration solutions to tackle airborne particulates and contaminants in a wide range of settings, from residential to commercial and industrial applications.

High-quality filters not only purify the air you breathe by trapping particles but also facilitate unobstructed air flow, contributing to reduced operational costs.
Frequently Asked Questions
Minimum Efficiency Reporting Value (MERV) is a filter industry standard system that rates the overall effectiveness of air filters. Higher value MERV rating equates to finer filtration, meaning fewer dust particles and other airborne contaminants can pass through the filter. Other common ratings found within certain brands and stores includes FPR, MPR. They all follow the same basic principal, the higher the number the greater overall effectiveness of the air filter.
Choosing the correctly sized air filter is important in order to keep air clean in your home. An improperly sized filter may have limited performance. Determining the proper air filter size can be confusing, since filter packages generally display two sets of dimensions. It is important to understand that these dimension sets are the nominal and actual dimensions of the filter, and differences between the two.
The best place to start is our filter search page that can be found at the following link or at the top of every page.
You can search by filter size, part number, model and more.
Tips: When using our search option to locate your filter size especially for Exact Filters® enter the exact size needed in the format shown here.
No spaces, fractions only 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8.
Most often there will be an arrow on the side of the filter which will indicate which way to insert the filter. The arrow will show which direction the air is to travel through the filter. If there is no arrow the filter can be installed in both directions.
Remember your filter is designed to protect your system first and foremost. Air should be traveling through the filter before your blower and system.
Furnace, AC and HVAC filters are most often measured in inches. A nominal measurement would be a rounded number like 20x25x1, rounded up to the nearest inch. These filters if measured with a tape measure would likely be closer to 19 ½" x 24 ½" x ¾" which would be the actual true exact size.
