Exact Filters 34-1/4″ x 30″ x 1″ Pleated MERV 13 Value-Optimized Filter (12-Pack)

Description

Exact Filters® produces this 34-1/4 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 34-1/4 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.

At MERV 13, this filter removes a significantly larger share of fine particulate from your return air than standard mid-efficiency ratings — including smoke, bacteria-sized particles, and the fine dust that tends to resettle faster after cleaning. Because the media is denser, a properly sized HVAC system matters: check your blower’s static-pressure headroom before upgrading.

Common applications for a 34-1/4 x 30 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.

• Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
