The Everpure OCS2 (EV9618-02) has a rated capacity of 3,000 gallons or 6 months of service life, whichever comes first. It is specifically engineered for office coffee service (OCS) applications, delivering consistent water quality for brewing equipment in small to medium-volume locations. Replacing the cartridge at the recommended interval ensures optimal flavor extraction and protects your coffee or espresso machine from scale and sediment damage.

The Everpure OCS2 features a 5-micron filtration rating, which effectively captures fine particulates, dirt, and sediment that can cloud beverages or clog brewing equipment. Combined with Everpure's proprietary Micro-Pure II media and precoat filtration technology, the OCS2 reduces chlorine taste and odor while also inhibiting scale buildup through polyphosphate scale control—critical for preserving the lifespan of coffee makers, espresso machines, and hot beverage dispensers.

Yes, the Everpure OCS2 cartridge is tested and certified by NSF International against NSF/ANSI Standard 42 for aesthetic effects, including chlorine taste and odor reduction and particulate reduction (Class I). This certification verifies that the filter performs as claimed under rigorous third-party testing, giving office managers and foodservice operators confidence in the water quality feeding their coffee and beverage equipment.

The Everpure EV9618-02 OCS2 operates at a maximum flow rate of 0.5 GPM (gallons per minute) with a pressure range of 10–125 psi and a temperature range of 35–100°F. It is purpose-built for office coffee service applications, including single-cup brewers, pod-based coffee machines, and small commercial coffee makers, where moderate water volume and superior taste quality are essential.

The OCS2 uses Everpure's signature quick-change (QC) head design, allowing for a simple twist-off, twist-on cartridge replacement without tools or shutting off the water supply at the source. To replace: turn the old cartridge a quarter-turn counterclockwise to release it from the EV9259-12 or compatible QC head, insert the new OCS2, and rotate a quarter-turn clockwise until it locks. Flush the new cartridge for 5 minutes or until water runs clear before reconnecting to your coffee equipment.
