Description
When your HVAC system calls for a 38-3/8 x 35 x 1″ filter and the standard aisle doesn’t carry it, this Exact Filters® unit is cut to your exact 38-3/8 x 35 x 1″ spec — no shims, no gaps, no bypass air.
A properly fitting filter seals against the housing, so all return air is forced through the media instead of leaking around the frame.
This MERV 13 pleated filter is the highest-efficiency option we produce in the Exact Filters® custom-size line. It’s commonly chosen by allergy-sensitive households, buildings in wildfire-smoke regions, healthcare and education facilities, and anyone wanting the deepest particulate capture we offer.
Specifications
- Nominal size: 38-3/8 x 35 x 1″
- Actual dimensions: 38-3/8 x 35 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
Common applications for a 38-3/8 x 35 x 1″ custom filter include retrofit installations, legacy HVAC systems installed before standard sizes were codified, built-in return grilles that were framed to non-standard dimensions, and commercial unit housings that don’t match any current off-the-shelf size.
Features
- Made to your exact 38-3/8 x 35 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
- Sold as a 12-pack so you have a full year of replacements on hand
- Orientation arrow printed on the frame to ensure correct airflow direction at install
