20x25x4 MERV 11 air filter efficiency ratings make the filter a tremendous upgrade from ordinary pleated filters in applications such as residential, hospitals, laboratories and pharmaceutical plants, and commercial office buildings in any system in which a higher degree of clean air is required. Although the MERV 11 provides excellent protection, it still allows good air flow for your heating and cooling system to perform efficiently saving on energy costs and help reducing costly repairs.
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

These are fabulous! They’re a huge value over the typical 3M filters and every bit as good. We got the 20x25x4 Merv 11 and it worked out to about $12 a filter. Will be stocking up!
