Description
Built to order in the precise 30-5/8 x 34-1/2 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.
A properly fitting filter seals against the housing, so all return air is forced through the media instead of leaking around the frame.
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: 30-5/8 x 34-1/2 x 1″
- Actual dimensions: 30-5/8 x 34-1/2 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
The 30-5/8 x 34-1/2 x 1″ dimension is one of the many non-standard sizes we make on demand, serving both retrofit installations in older homes and light-commercial properties where the return housing dates to an older era of HVAC construction.
Features
- 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
- 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
