Hi there. The carbon filter we require is for a water bottle. Is 3 "long x 7/8” wide We expect to buy a high volume of these. Please see the picture below of the green and black cap and filter. The carbon filter fits inside the long green tube with the holes in it. We have the caps and tube, just need the carbon filter.
