20x25x2 Air Filter for A/C or Furnace.  
Actual Size: 19-1/2 x 24-1/2 x 1-3/4.  
Filter Rating: MERV 11 | FPR 7 | MPR 1000.    

Utilizing our MERV 11 20x25x2 air filter provides outstanding filtration for residential or commercial environments. The Multi-Pleat MERV 11 furnace a/c filter is produced with a highly specialized; dual layered 100% synthetic media, developed for use in extended surface air filters. The new media is composed of an upstream electrostatically enhanced layer, and a downstream mechanical layer. This filter is an economical alternative if you're looking for a higher quality air filter without paying a premium price.

MERV 11 Specifications:
• Effectively reduces pollen, dust, pet dander, mold spores, dust mites, bacteria, smoke, smog and other allergens from the air in your home or business.
• Super charged, electrostatically enhanced media.
• Specifically manufactured for system applications requiring improved medium efficiency, non-shedding filtration media.
• MERV 11 (Minimum Efficiency Reporting Value) based on ASHRAE Test Standard 52.2-2012
• Synthetic media made up of continuous hydrophobic fibers which do not absorb moisture and can withstand turbulent, high velocity conditions.
• Manufactured for system applications requiring high efficiency, non-shedding filtration media.
• Effective in single filter applications or as improved pre-filter substitutes for disposables, permanent metal filters or media pad/frame filters.
• Improved overall particle size efficiency due to continuous fiber structure and dual-stage electrostatic enhancement which captures an increased amount of smaller particulate than conventional glass media.
• Pleat configuration: Formed into aerodynamic, semi-tapered, wedge-shaped pleats expanding its capability to capture contaminants.
• Recommended to replace at least every 90 days
• Made in the USA
