Hi John, thanks for writing in. Those filters are not considered primary and secondary. The FC15B filters carbon and is for chlorine, taste, and odor (CTO) whereas the FM15B filters magnesium and iron.
Hi Dan. You will need to remove the new filter from the packaging and insert the cartridge directly into the housing, making sure it slips over the standpipe in the bottom of the housing.
