xUpgrade your home air with the Aprilaire 401 replacement filter
Air quality matters for daily comfort, especially when your HVAC system runs frequently. The Aprilaire 401 Healthy Air 10 filter is designed to fit AprilAire and Space-Gard Air Cleaner Model 2400, delivering reliable filtration as air moves through a MERV 10 media. This replacement helps reduce common indoor particles, contributing to a sense of freshness in living spaces and making it easier for your family to breathe through busy days.
What this filter does
- Captures a range of airborne particles as air passes through the laminate media, including dust, pollen, mold spores, bacteria, and pet dander.
- With a 6-inch depth, it provides more surface area for filtration than typical 1-inch designs, supporting efficient particle capture over time.
Long-lasting protection and maintenance
- Designed for up to 12 months of filter life in many homes, which can reduce the frequency of replacements.
- Pack of 2 offers convenient replacements, helping you keep your purifier ready for seasons with higher particulates.
- Regular replacement supports steady HVAC performance by minimizing dust buildup inside the system.
Compatibility and upgrade options
Fully compatible with AprilAire or Space-Gard Air Cleaner Model 2400. For those seeking higher filtration performance, consider the optional Model 1413 Upgrade Kit, which swaps the 401 with a 413 filter and a new frame, removing pleat spacers for streamlined airflow.
Quality and origin
Designed and manufactured in the USA, this genuine Aprilaire replacement part is built to fit precisely and sustain the purifier’s intended performance.
What to expect at home
After a swap, you may notice a cleaner appearance in rooms that see frequent air cycling and a steadier draft of conditioned air. The packaging clearly lists the nominal size (16 x 25 x 6) to help you identify the right fit.
Notes on filtration standards
MERV is a filtration efficiency rating; higher numbers indicate stronger capture. This filter carries a MERV 10 rating and aligns with ASHRAE 52.2 testing standards.
