Overview
Not a one-inch furnace filter you slide into a grille slot, this is a four-inch deep pleated media cartridge built for a specific air cleaner cabinet. Air moves through the pleated synthetic fiber, where particles are trapped across the full media face, and the Self-Seal edge closes off the gap around the frame so the airflow cannot slip past unfiltered. The Interlock Rail System seats it in the cabinet in three steps.
Owners of the matching AprilAire cabinet get a filter that holds a large media area and is rated to last up to a year, so changes drop from several a year to one. The limits are the cabinet itself and the fit: if the equipment is not the listed model or fitted with the upgrade kit, the cartridge has nowhere to seat.
Who it's for
Homes with an AprilAire air cleaner cabinet already installed, where the return air passes through a deep media slot instead of a thin grille filter. Anyone with a plain one-inch filter slot, or an air cleaner outside the listed model and kit, should look elsewhere.
Pros and cons
- Deep pleated media holds more dust
- MERV 13 catches fine allergens
- Rated to last up to a year
- Self-Seal edge limits air bypass
- Only fits listed cabinets and the upgrade kit
- No warranty stated
- Filter media only, no frame or rails included
- Cabinet purchase is separate
Performance notes
Filtration here comes from media depth and pleat count: the deeper cartridge spreads the same airflow over a much larger fiber area, which lowers resistance and lets the filter load up with dust before it restricts the system. The sealing edge matters as much as the media, since air that skirts the frame carries its particles straight past. Life depends on runtime and how dirty the return air is, not on the calendar.

Frequently asked questions
What comes in the box with the AprilAire 113 filter?
The pack holds one 113 filter media cartridge. No frame, rails, or other hardware are listed as included, so the cabinet and its rail system are expected to already be in place.
Will the AprilAire 113 fit an air cleaner other than the 1110?
The listing names AprilAire Model 1110 and competitive models that use the 4898 upgrade kit. Cabinets outside those two cases are not covered by the stated compatibility.
How often does the AprilAire 113 need changing?
The media is described as supporting up to 12 months of filter life, with low initial resistance and high dust holding capacity. Actual timing depends on runtime and how much dust reaches the return.
Is the AprilAire 113 a one-inch furnace filter?
No. It is a four-inch deep pleated media cartridge sized for a whole-house air cleaner cabinet, not a thin filter that slides into a standard return grille.
What does MERV 13 mean on this filter?
MERV is the scale used to rate filter effectiveness, and higher values mean more effective filtration. This cartridge is performance tested to the ASHRAE 52.2 standard at MERV 13.
