IMPORTANT:

  • The calculator is a guide only and does not guarantee results to fill the hood correctly. Not all hoods are designed the same. There is a (+/-) 1/8” size tolerance.
  • Please double check your measurements to avoid returns. Only unused filters can be returned. Customer pays return shipping.
  • Horizontal measurement should just be the area that needs to be filled by the hood filters. Keep in mind that you’ll need extra space to get filters in and out of the hood.
  • Please watch the beginning of this video if you are not 100% sure how to measure properly.
