Description
Exact Filters® produces this 32-1/8 x 34-5/8 x 1″ filter to your measurements, so instead of trimming, taping, or forcing a “close enough” size into place, you drop in a filter that fits your 32-1/8 x 34-5/8 x 1″ slot the first time.
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.
MERV 13 targets the fine particulate fraction that lower MERV ratings allow through — including smoke, bacteria-carrying dust, and combustion byproducts. Airflow resistance is higher than MERV 8 or 11, so systems with borderline static pressure should be evaluated before switching up.
Specifications
- Nominal size: 32-1/8 x 34-5/8 x 1″
- Actual dimensions: 32-1/8 x 34-5/8 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
Common applications for a 32-1/8 x 34-5/8 x 1″ custom filter include retrofit installations, legacy HVAC systems installed before standard sizes were codified, built-in return grilles that were framed to non-standard dimensions, and commercial unit housings that don’t match any current off-the-shelf size.
Features
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
- Cardboard frame with reinforced media for structural stability during handling and installation
- Made to your exact 32-1/8 x 34-5/8 x 1″ specification — no trimming or taping required at installation
