Description
Exact Filters® produces this 34-1/4 x 26-3/4 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 34-1/4 x 26-3/4 x 1″ slot the first time.
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: 34-1/4 x 26-3/4 x 1″
- Actual dimensions: 34-1/4 x 26-3/4 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
The 34-1/4 x 26-3/4 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
- Orientation arrow printed on the frame to ensure correct airflow direction at install
- Sold as a 12-pack so you have a full year of replacements on hand
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
- Made to your exact 34-1/4 x 26-3/4 x 1″ specification — no trimming or taping required at installation
