Aprilaire 610 Replacement Filter for 1625FG – MERV 11, 16x25x4, USA Made

Refresh the air you breathe with the Aprilaire 610 Replacement Filter, designed to work with the AprilAire Whole House Air Purifier 1625FG. This 4-inch-thick filter delivers a broad filtration surface and a trusted MERV 11 rating to capture a wide range of airborne particles as air circulates through your system.

In real-world use, the 610 helps reduce the amount of dust and other irritants settling on furniture and floors by trapping pollen, mold spores, bacteria, pet dander, and fine dust before they reach living spaces. While filtration alone isn’t a guarantee against allergens, many homeowners notice fewer surface dusting needs and a steadier indoor air flow as the purifier operates.

Key benefits

• Traps pollen, mold spores, bacteria, pet dander, and dust with a MERV 11 rating.
• The 610 features 23.6 square feet of filtering media, offering more filtration area than typical slim designs.
• Self-Seal Technology minimizes air bypass so treated air stays in circulation.
• Easy 1-2-3 installation with the Interlock Rail System—unpack, slide in, close the door.
• 4-inch depth and robust construction yield a long service life with a manageable pressure drop.

Performance in your home

• Cleaner-looking air and less visible dust on surfaces, depending on room conditions and use.
• Helps protect the HVAC system by capturing contaminants before they enter the blower and ducts.
• Up to 12 months of filter life under typical use, reducing maintenance frequency and costs.

The Aprilaire 610 is a genuine, USA-made replacement designed to fit AprilAire Air Cleaner Model 1625FG. It also works with select competitors when used with the AprilAire 4897 Upgrade Kit, and comes with the Pure Fit Promise to ensure a precise, secure fit. This 16x25x4 nominal filter size is a straightforward match for many setups, providing reliable performance across seasons.
