Choosing Hood Filter Size

Hood exhaust filters should always be installed with the baffles running in the vertical (top to bottom) position. This allows the grease to run down the baffles to the grease trough and then to be collected inside the hood grease containment system. All filters should be tight fitting in the exhaust hood. Note, no gaps should be present! Industry standard sizes are ordered with the vertical (top to bottom) dimension first, the Horizontal dimension Second. See examples Below.

Hood Filter sizes should be ordered with the vertical (top to bottom) dimension first and the horizontal (left to right) dimension last. Review the example above and be certain to round up to the nearest ½”, then select the corresponding size when ordering. If actual filter size is 19-1/2” X 19-1/2” you would order a 20” X 20” filter.
