We designed the 3M™ OCS Replacement Cartridge, Model CS-21 which is our replacement filter cartridge designed to reduce particles for office and cafeteria hot drink preparation.

The 3M™ OCS Office Coffee Replacement Cartridge, Model CS-21 provides consistent high-quality water for office coffee and cafeteria hot drink applications. Our filter products are designed to improve the taste and clarity of water by reducing sediment, chlorine taste and odour, and to protect equipment from the harmful effects of chlorine corrosion. A scale inhibitor reduces the ability of ions to form hard scale further extending the life of your equipment. These replacement cartridges reduce particles as small as 5.1 and even 0.5 micron. This means a range of microscopic particles are effectively reduced helping to protect your plumbed-in single service coffee dispenser and coffee brewers. The innovative Sanitary Quick Change (SQC) design means the cartridges are hygienic by design, allowing for fast and easy cartridge change-outs that require no filter wrench or contact with the filter media. Just a quarter turn is all it takes to remove and replace the filter cartridge, minimising the possibility of leakage and media contamination. Models range from 800 gal / 3028 L or 80 cups per day up to 3500 gal / 13,249 L or 466 cups per day and can improve the taste, smell, clarity and overall consistency of your brewed beverages. 3M™ Office Coffee/Hot Cup Replacement Filter Cartridges are NSF certified, including CS-11, CS-21, CS-31, CS-51, CS-61, CS-71, and HC101-S.
