The Aprilaire 513 is a MERV 13-rated filter, designed specifically for use in Aprilaire Model 5000 Electronic Air Cleaners. It captures airborne particles as small as 0.3 microns, including dust, pollen, pet dander, mold spores, bacteria, and virus-carrying particles, making it ideal for households concerned with allergies, asthma, or overall indoor air quality.

The Aprilaire 513 replacement filter is engineered exclusively for the Aprilaire Model 5000 Whole-House Air Cleaner. It is not interchangeable with other Aprilaire media air cleaner models such as the 2200, 2400, or 4200. Always verify your unit's model number before ordering to ensure a proper fit and optimal electrostatic filtration performance.

Aprilaire recommends replacing the 513 filter every 12 months under normal operating conditions. However, homes with pets, smokers, high dust levels, or residents with allergies may need replacement every 6–9 months. Regular replacement ensures the Model 5000's patented dual-stage electronic and media filtration continues to capture up to 98% of airborne particles effectively.

Unlike standard 1-inch furnace filters, the Aprilaire 513 is a deep-pleated media filter designed to work with the Model 5000's electrostatic charging technology. The pre-charged media works in tandem with the unit's electronic precipitator to trap ultra-fine particles down to 0.3 microns, delivering hospital-grade air filtration without restricting airflow through your HVAC system.

Yes, the Aprilaire 513 sold here is a genuine OEM (Original Equipment Manufacturer) replacement filter made by Aprilaire. Using authentic Aprilaire 513 media ensures proper fit within the Model 5000 cabinet, maintains the manufacturer's warranty coverage, and guarantees the MERV 13 performance rating that aftermarket alternatives may not consistently deliver.
