Dimensions: 12 x 17 x 3/8
Aluminum filter 12 x 17 x 3/8. Used on all microwave shelf hoods. Models HS100, HS200. HS201, HS202 HS21-421 and HS21-431. The Rangaire part number is 610037 Rangaire’s original size of this filter was 12-1/4 x 17-1/8. I got plenty phone calls saying the fit was too tight. We dropped the size to 12 x 17 and that ended the problem.
