24x24x4 Air Conditioner and Furnace Filter.
Actual Size: 23-3/8 x 23-3/8 x3-3/4.
Filter Rating: MERV 11 | FPR 7 | MPR 1000.

The 24x24x4 MERV 11 pleated A/C furnace air filters are constructed using electrostatically charged filter media from recognized leaders in the USA filtration industry. The 100% synthetic material offers significantly higher filtration efficiency and captures the smallest and most harmful airborne particles and allergens, such as particles that carry viruses and bacteria, pollen, mold spores, fine dust and pet dander. The MERV 11 filter is a perfect option for homeowners and business looking to improve indoor air quality at an economical price.

MERV 11 Specifications:
• Manufactured for system applications requiring high efficiency, non-shedding filtration media.
• 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.
• Enhanced 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.
• Suggested to change at least every 3 Months
• Made in the United States
