This Instapure R2 ESSENTIALS 4-pack is the year supply of replacement filter cartridges for the popular Instapure F-2C and F-2 tap-mounted water filtration systems. Each filter delivers approximately 3 months of clean filtered water at typical residential use rates, meaning the 4-pack covers a full calendar year of replacements at a single purchase.
ANSI/NSF Class II certification for chlorine taste and odor reduction means the cartridges are independently tested and verified by NSF International — not just marketing claims. Class II is the appropriate rating for tap-mounted residential systems where chlorine is the primary water-quality concern. The R2c filters are a cost-effective method to produce clean, better-tasting water without committing to a more expensive under-sink filtration installation.
For households using Instapure F-2C or F-2 tap filters as their primary drinking water filtration, this 4-pack is the right yearly maintenance subscription. Made by Instapure in Hayward, California — one of America’s long-time tap-mounted water filtration manufacturers. Pop off the old cartridge, snap in the new one, and you’re back to clean water.
