Review on 🔍 Four-Pack of Filterbuy Silver 14x24x1 HVAC AC Furnace Filters, MERV 8 Pleated - Enhanced SEO by Michael Wilson

These filters run small! From my understanding of how filters are measured, the size listed should match the filter opening. In this case, the opening should be 14x24x1. They are actually 13 3/8 x 23 3/8 x 3/4. According to the standard for measuring filters, measured values should be rounded to the nearest inch or half inch. These filters are designed to fit the 13 1/2X 23 1/2X1 aperture. If you want to mount a 14X 24X 1 hole like mine you will find they are 1/4" smaller all around.
