The PREpleat M13 pleated filter has a low initial resistance and supports achievement of LEED® credits by significantly improving Indoor Air Quality (IAQ) and reducing energy consumption.
The PREpleat M13 filter provides an initial efficiency of MERV 13 per ASHRAE Standard 52.2 at a resistance of only .20" w.g. (2" depth) when operating at airflow velocity of 375 FPM—and only 0.30" at 500 FPM.
Superior Design and Construction
Media: 100% non-woven synthetic media manufactured from recyclable material.
Media Support: Diamond-shaped expanded metal maintains maximum support while avoiding air bypass.
Pleat Design: V-Pleat design minimizes resistance, keeping consistent pleat count, height, and shape.
Frame: Heavy-duty two-piece moisture-resistant frame includes diagonal and horizontal support members bonded to the media on the air entering and leaving sides. This is a durable frame for any commercial and industrial application.
Operating Temperature Limits: Maximum operating temperature is 180°F (82°C).
PREpleat M13 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.

MERV Rating: MERV 13
Nominal Size: 20x25x4
Actual Size: 19-1/2 x 24-1/2 x 3-3/4
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 13 rating reduces up to 95% of airborne particles including dust and lint, dust mite debris, pollen, pet dander, mold spores, bacteria, microscopic allergens, virus carriers, most smoke, smog, oil smoke, as well as lead dust. Hospital-grade air filtration provides maximum protection for your home or business.

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.
