AprilAire 2210 filter size: 213, nominal 20 x 25 x 4
The AprilAire 2210 whole-house air cleaner ships with a 213 filter. AprilAire gives the 213 a nominal size of 20H x 25W x 4D and an actual size of 20.6H x 26.63W x 4D.
Which filters does AprilAire list for the 2210?
| Filter | Rating | Where AprilAire says so |
|---|---|---|
| 213 | MERV 13 (ships with the 2210) | 2210 product page; spec sheet |
| 210 | MERV 11 | 2210 product page (“Also compatible with”); spec sheet |
| 213CBN | MERV 13 + carbon | 2210 product page |
| 216 | MERV 16 | 2210 product page |
AprilAire's 213 page also says a newer UK213 filter with “One-Time Upgrade Rails” replaces the 213. Check the UK213 size on AprilAire's own page before you order it.
Which other cabinets take the 213?
AprilAire's 213 page lists these compatible models: 1210, 1620, 2210, 2216, 3210, 4200, 2120 with Upgrade Kit 1213, 2200 with Upgrade Kit 1213, UV12 and UV22.
How big is the 2210 cabinet?
AprilAire lists the 2210 cabinet's actual measurements as 22.0625H x 6.75W x 27.375D (inches).
Why is the actual size larger than nominal?
Most 1 in filters are cut smaller than nominal. The 213 is the opposite: its actual width, 26.63 in, is larger than its 25 in nominal width. A generic “20x25x4” filter from another maker may not match it. Read the model number on your cabinet and use the filter number the cabinet maker lists.
