Exact Filters 36.5 x 28.875 x 1 Inch Pleated HVAC Filter, MERV 13 Efficiency Rating (12-Pack)

Description

Exact Filters® produces this 36-1/2 x 28-7/8 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 36-1/2 x 28-7/8 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.

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.

Common applications for a 36-1/2 x 28-7/8 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

• Orientation arrow printed on the frame to ensure correct airflow direction at install
• Made to your exact 36-1/2 x 28-7/8 x 1″ specification — no trimming or taping required at installation
• Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
• Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
