Aprilaire UK213 Merv 13 Air Filter Upgrade Kit

Product Description

The APRILAIRE UK213 is a MERV 13 air filter upgrade kit designed as a replacement for the sunsetting 213 filter. The kit includes a 3-inch deep MERV 13 media filter with TriPure Technology and one-time upgrade rails that allow installation into existing AprilAire media air cleaner cabinets without cabinet replacement. At MERV 13, the filter captures up to 95% of household dust, mold, and allergens, and 92% of viruses based on ASHRAE 52.2 testing using the MS-2 virus. Licensed HVAC technicians and indoor air quality installers are the primary service trade for this product.

The UK213 is intended for residential forced-air HVAC systems equipped with existing AprilAire media air cleaner cabinets that previously accepted the 213 filter. The upgrade rails are included for a one-time transition to the new rail and media interface. The filter measures 20 inches x 25 inches with a 3-inch depth and is designed for a 12-month replacement cycle under normal operating conditions. It is manufactured in the USA and carries AprilAire branding as a genuine OEM-style replacement product.
