20x24x4 Air Conditioner and Furnace Filter.
Actual Size: 19-3/8 x 23-3/8 x 3-3/4.
Filter Rating: MERV 11 | FPR 7 | MPR 1000.
Our 20x24x4 MERV 11 A/C furnace filters provide a combination of efficiency, economy, and excellent overall performance. The MERV 11 air filters are an exceptional choice in applications where filter change schedules are based on preventive maintenance schedules and guarding your environments from harmful airborne particles. Removing these airborne particles can help improve allergies and alleviate sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing. Aside from the health benefits, these HVAC filters will also extend the life of your heating and cooling system by making it work more efficiently.
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 d 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
