Description
Designed for homeowners and facilities managers dealing with an unusual 38-3/8 x 34 x 1″ filter housing, this Exact Filters® filter is produced on-demand to fit your opening precisely.
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.
MERV 13 is the top efficiency offered in the Exact Filters® line. It captures the broadest range of airborne particles we make, including fine dust, smoke particles, and the submicron fraction that carries many allergens and bioaerosols. Buildings dealing with wildfire smoke, indoor air-quality concerns, or sensitive occupants commonly step up to this rating.
Specifications
- Nominal size: 38-3/8 x 34 x 1″
- Actual dimensions: 38-3/8 x 34 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
Customers typically order a 38-3/8 x 34 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
- Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Made to your exact 38-3/8 x 34 x 1″ specification — no trimming or taping required at installation
