Description
When your HVAC system calls for a 29-7/8 x 12-1/8 x 1″ filter and the standard aisle doesn’t carry it, this Exact Filters® unit is cut to your exact 29-7/8 x 12-1/8 x 1″ spec — no shims, no gaps, no bypass air.
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 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: 29-7/8 x 12-1/8 x 1″

The 29-7/8 x 12-1/8 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
- 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 29-7/8 x 12-1/8 x 1″ specification — no trimming or taping required at installation
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
