29-5/8″ x 38-1/4″ x 1″ MERV 13 Pleated HVAC Replacement Filter (12-Pack)

Description

Built to order in the precise 29-5/8 x 38-1/4 x 1″ dimension you need, this Exact Filters® air filter solves a problem standard catalogs can’t — a true custom fit for systems that don’t accept common filter sizes.

Filter bypass — air slipping past a loose frame instead of through the pleats — is one of the most common reasons a filter underperforms its MERV rating in the real world. A precise fit closes that gap.

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.

Specifications

• Nominal size: 29-5/8 x 38-1/4 x 1″
• Actual dimensions: 29-5/8 x 38-1/4 x 3/4″
• Efficiency rating: MERV 13
• Quantity: 12 filters per carton

Customers typically order a 29-5/8 x 38-1/4 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
• Cardboard frame with reinforced media for structural stability during handling and installation
• Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
• Sold as a 12-pack so you have a full year of replacements on hand
