This air filter is made to a 30-1/4 x 15-1/2 x 1 nominal size for HVAC systems, air handlers, and return grilles that require an exact custom dimension rather than a standard retail size.
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: 30-1/4 x 15-1/2 x 1
- Actual dimensions: 30-1/4 x 15-1/2 x 3/4
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
Common applications for a 30-1/4 x 15-1/2 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
- Made to your exact 30-1/4 x 15-1/2 x 1 specification no trimming or taping required at installation
- Orientation arrow printed on the frame to ensure correct airflow direction at install
- Cardboard frame with reinforced media for structural stability during handling and installation
- Sold as a 12-pack so you have a full year of replacements on hand
