Elevate Your Home’s Breath: Aprilaire 401 Replacement Filter – Fortified Protection, Lasting Freshness

Experience the transformative power of clean air with the Aprilaire 401 Replacement Filter. This genuine upgrade for your Aprilaire 2400 or Space-Gard 2400 air purifier isn’t just a filter – it’s an investment in superior protection, effortless breathing, and long-lasting peace of mind.

Air quality matters. That’s why you trust AprilAire to keep your home environment safe for you and your family. The AprilAire 401 Healthy Air 10 Air Filter removes airborne particles as they pass through the MERV 10 filter including dust, pollen, mold spores, and pet dander. That means it makes the air throughout your home fresh and healthy so your family can breathe easily.

Annual air filter replacements are a great way to keep your home and family protected. Your HVAC system is protected from airborne particles too, which helps lower your energy costs and can prolong the life of your equipment. Lengthen your HVAC system’s life and improve your home’s energy efficiency by reducing dust buildup.

Efficient home and system protection – with up to 12 months of filter life, you also save time on furnace filter changes compared to the traditional 1-3 month filter. Aprilaire 6-inch filters provide more filter area for harmful particles to be captured compared to common 1-inch filters.

The AprilAire 401 Healthy Air 10 Air Filter has a nominal air filter size of 16 x 25 x 6 inches and is compatible with AprilAire and Space-Gard Air Cleaner Model 2400. Illustrated packaging includes detailed air filter replacement instructions. Designed and made in the USA.

Save time and upgrade performance – consider the AprilAire Model 1413 High-Performance Upgrade Kit to replace your original AprilAire 401 filter with a high-performance 413 filter and new filter frame system, eliminating pleat spacers (Model 1413 sold separately).

Note: MERV is a scale used to measure the effectiveness of air filters. Higher number values translate to more effective filtration. *Performance tested to ASHRAE 52.2 Standard, minimum efficiency reporting value – MERV 10.
