Description
Exact Filters® produces this 28 x 30 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 28 x 30 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 11 sits in the sweet spot for “upgraded” filtration: substantially better particle capture than MERV 8, without the static-pressure concerns that come with MERV 13 on older or undersized systems. It’s the rating we recommend most often to customers asking “what should I step up to?”
Specifications
- Nominal size: 28 x 30 x 1″
- Actual dimensions: 27-3/4 x 29-3/4 x 3/4″
- Efficiency rating: MERV 11
- Quantity: 12 filters per carton
This 28 x 30 x 1″ filter size is frequently ordered by homeowners with older systems, property managers handling mixed-vintage HVAC equipment, and facilities maintenance teams servicing buildings where no two return grilles seem to measure the same.
Features
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
- Cardboard frame with reinforced media for structural stability during handling and installation
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Sold as a 12-pack so you have a full year of replacements on hand
