Complete 12-Month Filter Set: The F5DS-NC set lasts up to 12 months and includes 2×FPDS sediment filters, 1×FGKDS granular activated carbon & KDF composite filter, 1×FCNCDS SGS-tested carbon block filter, and 1×FTDS post-carbon filter, serving as a complete replacement solution for iSpring DS4B-NC and DS4S-NC bottleless water dispensers
SGS-Tested Chloramine Reduction: The FCNCDS carbon block filter has been tested by SGS and proven to remove up to 99.4% of chlorine and chloramines, while also improving water clarity and enhancing taste
Freshness Preserved in Every Filter: Each cartridge is individually sealed to maintain freshness until installation, and users should unwrap all cartridges before installation and flush the system for 3 to 5 minutes prior to drinking
Hassle-Free, Tool-Free Installation: The F5DS-NC filters are designed for quick, easy replacement with iSpring DS4B-NC and DS4S-NC models, making routine maintenance simple and fast
Not for TDS Reduction: This filter set does not reduce Total Dissolved Solids (TDS) like a reverse osmosis membrane, so customers seeking TDS removal should consider an iSpring Reverse Osmosis (RO) system
