Elevate Indoor Air Quality with the Aprilaire 413CBN Replacement Filter

Home life is seasoned with laughter, meals, and everyday scents. The Aprilaire 413CBN Healthy Air 13+ replacement filter adds activated carbon to a trusted MERV 13 filtration layer, targeting odors from cooking and pets while continuing to trap common airborne particles as air moves through the media. This 4-inch filter is designed to fit your Aprilaire purifier, helping your system maintain its performance while you enjoy a fresher home environment.

Activated carbon in the 413CBN helps address everyday scents, including cooking aromas, pet odors, and other VOC-associated smells. As air flows through the filter, odors can be reduced alongside the standard allergen capture provided by the MERV 13 media, offering a practical upgrade for households that want a balanced approach to cleaner air and fewer persistent smells.

When installed, the combination of a broad filtering surface and carbon media supports steady airflow and filter life. The filter features a substantial 24.5 square feet of filtering media, a 4-inch depth, and Self-Seal Technology to minimize air bypass. These design choices are aimed at maintaining filtration efficiency while keeping maintenance manageable for busy families and pet owners.
