This American Filter Company AFC-CH-104-9000S is the chloramines-grade replacement cartridge for 3M CS-61 commercial foodservice installations. The CH designation indicates chloramines-specific catalytic carbon construction — important for the majority of major American municipalities now using chloramines (chlorine + ammonia) instead of pure chlorine for water disinfection.
Catalytic carbon filtration handles chloramines effectively, where standard activated carbon would let chloramines pass through largely unchanged. Chloramine residue impacts beverage taste and ice clarity in commercial foodservice — getting the chloramines-grade cartridge matters for any commercial operation in a chloramines-disinfected city.
For commercial coffee shops, restaurants, and beverage operations running 3M CS-61 installations, this AFC chloramines-grade replacement is the right cartridge. USA-made by American Filter Company. “Made in U.S.A.” tagged in the AFC catalog throughout their product line.
