The 20x20x2 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:
• MERV 11 (Minimum Efficiency Reporting Value) based on ASHRAE Test Standard 52.2-2012
• 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 engineered for system applications requiring improved medium efficiency, non-shedding filtration media.
• 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.
• Successful 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
• Manufactured in the USA
