32.25 x 11.25 x 1 in MERV 13 Pleated AC Air Filter – 12-Pack

Description

This 32-1/4 x 11-1/4 x 1″ Exact Filters® air filter is manufactured to your exact dimensions, eliminating the guesswork of matching an off-the-shelf filter to a non-standard 32-1/4 x 11-1/4 x 1″ opening.

Even a quarter-inch of gap around a filter can allow a significant percentage of return air to bypass the media entirely, which is why the exact fit matters as much as the filter’s efficiency rating.

At MERV 13, this filter removes a significantly larger share of fine particulate from your return air than standard mid-efficiency ratings — including smoke, bacteria-sized particles, and the fine dust that tends to resettle faster after cleaning. Because the media is denser, a properly sized HVAC system matters: check your blower’s static-pressure headroom before upgrading.

Customers typically order a 32-1/4 x 11-1/4 x 1″ custom filter because their system is older, was built by a regional manufacturer, was retrofitted, or was framed on-site by an installer who didn’t conform to a standard filter dimension. If that describes your situation, you’re in the right place.

Features

• Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
• Sold as a 12-pack so you have a full year of replacements on hand
• Orientation arrow printed on the frame to ensure correct airflow direction at install
• Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
