Description
Exact Filters® produces this 34-1/2 x 35-3/8 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 34-1/2 x 35-3/8 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 is the top efficiency offered in the Exact Filters® line. It captures the broadest range of airborne particles we make, including fine dust, smoke particles, and the submicron fraction that carries many allergens and bioaerosols. Buildings dealing with wildfire smoke, indoor air-quality concerns, or sensitive occupants commonly step up to this rating.

The 34-1/2 x 35-3/8 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.

- Cardboard frame with reinforced media for structural stability during handling and installation
- Made to your exact 34-1/2 x 35-3/8 x 1″ specification — no trimming or taping required at installation
