The Aprilaire 413 Healthy Air 13 Filter is a 16x25x4 replacement built to live inside your whole-house air purifier. As air travels through this MERV 13 media, a broad spectrum of common indoor allergens—pollen and mold spores, bacteria, pet dander, dust particles, and even dust mites—are captured and held in the filter fibers. The result can be air that feels crisper and less laden with irritants, especially for households dealing with seasonal allergies or sensitive noses.\u003c\/p\u003e\n\u003cp\u003eBeyond filtration, this filter supports your HVAC system by reducing dust buildup and helping maintain steady airflow. The 4-inch depth yields a substantial 24.5 square feet of filtering area, which means more contact time between air and media and less resistance as dust accumulates. While exact results depend on your environment, you may notice easier operation of your system and a more consistent air flow across filtration cycles.\u003c\/p\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eThe 413 uses Self-Seal Technology to minimize air bypass and features an Interlock Rail System for a straightforward three-step replacement. No extra cardboard or metal reinforcements are needed—unpack, slide in, close the door, and you are done. The nominal size 16x25x4 inches helps you identify the correct replacement, though actual dimensions may vary slightly by batch. Made in the USA, this filter aligns with Aprilaire quality standards and is backed by the Pure Fit Promise for a reliable fit and dependable performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTraps common allergens such as dust, pollen, mold spores, bacteria, pet dander, and dust mites as air passes through the MERV 13 media.\u003c\/li\u003e\n  \u003cli\u003eLow initial resistance with high dust-holding capacity supports steady airflow and longer filter life.\u003c\/li\u003e\n  \u003cli\u003eSelf-Seal Technology minimizes bypass for more consistent filtration results.\u003c\/li\u003e\n  \u003cli\u003eInterlock Rail System enables a simple 1-2-3 installation without extra parts.\u003c\/li\u003e\n  \u003cli\u003eCompatible with multiple Aprilaire models including 1410, 1610, 2140, 2400, 2410, 2416, 3410, 4400, and Space-Gard 2400 with Upgrade Kit 1413.\u003c\/li\u003e\n  \u003cli\u003eMade in the USA and backed by a dedication to precise fit and reliable performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFit, compatibility, and what you get\u003c\/h3\u003e\n\u003cp\u003eThis pack includes two filters designed to fit a range of Aprilaire air cleaners.
