You will need a 4.5" W x 20" L filter cartridge.

Do you know if you current filter is a sediment filter or a carbon filter? Sediment filters reduce sediment down to a specified micron rating. Carbon filters also reduce sediment and improve the taste and odor of your drinking water.

I'll give you URL's of our most popular filters in the 4.5" W x 20" L size. If you know more details about your current filter in CG-20 system, I can give you a more specific recommendation.
