How to Choose the Right Filter Size

Now that you know why hood filters are needed, the next step is to determine the correct size. If you’re purchasing filters for a new hood system, you will also need to figure out how many filters are required to fill the open hood space. These are the most common questions we receive so we’ve created several tools to make this as simple as possible.

Measuring Existing Hood Filters

Industry standard sizes are stated with the vertical (top to bottom) dimension first and the horizontal (left to right) dimension second. The baffles should run up and down (vertically) when taking these measurements (see diagram below).

Remember: Height First, Width Second.
Trade Size Actual Dimensions
10” x 16” 9-1/2” x 15-1/2”
10” x 20” 9-1/2” x 19-1/2”
16” x 16” 15-1/2” x 15-1/2”
16” x 20” 15-1/2” x 19-1/2”
20” x 16” 19-1/2” x 15-1/2”
20” x 20” 19-1/2” x 19-1/2”

NOTE: Always round up to the nearest ½”. Actual filter size is typically ½” smaller than the stated size. For example, if the actual filter size is 9 ½” x 15 ½”, you would order a 10 x 16 hood filter.

Measure height (up & down with the baffles) and width (across the baffles), then record quantity below.
