Culligan C-2 Water Filter Cartridges

Hi: My question is…I have a filter system on our Ice Machine , this is a counter machine water and Ice…I use the Culligan C-2 Cartridge for replacement, and was looking around and found other kinds of the same size, I seen a filter #155031 R30-478, my problem with the filter i use now is
that sometime i get this dirty sediment. Am I using the right filter replacement cartridge?
Thank you

The C-2 filters are for taste & odor filtration (better quality), while the R30 are for sediment removal (first stage filtration).

If you get sediment in the water after it was filtered by the C2, this indicates filters are due for replacement.
