How do I measure my filter?

Before you measure, make sure your hood filter is placed in the vertical position with the baffles running up and down…just as they are placed in the hood system. Standard sizes are ordered with the vertical (top to bottom) dimension FIRST and the horizontal (left to right) dimension SECOND. Before ordering, be sure to round up to the nearest ½” – then select the corresponding size. For example, if your actual filter size is 9 ½” x 15 ½” – you would order a 10” x 16” hood filter. For more information on how to measure your hood filter or how to choose the right size, see the videos below or use our Hood Filter Sizing Calculator.
