Description
Exact Filters® produces this 38-3/8 x 30-1/8 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 38-3/8 x 30-1/8 x 1″ slot the first time.
A custom-cut filter keeps every cubic foot of return air flowing through the media rather than around it, which is the foundation of any effective filtration setup.
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: 38-3/8 x 30-1/8 x 1″

The 38-3/8 x 30-1/8 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
- Made to your exact 38-3/8 x 30-1/8 x 1″ specification — no trimming or taping required at installation
- Sold as a 12-pack so you have a full year of replacements on hand
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Cardboard frame with reinforced media for structural stability during handling and installation
