The Hydrotech RS-22-CB5-EB is a 5 micron carbon block prefilter engineered for Clack Microline compatible reverse osmosis systems, removing chlorine, taste, and odor before water reaches the TFC membrane. This second-stage filter is designed specifically for Hydrotech E, M, Pro, and 1240 Series systems, delivering reliable protection for downstream membrane life.

COMPATIBILITY & APPLICATIONS
System Compatibility
The RS-22-CB5-EB is designed as a direct replacement carbon block filter for Hydrotech reverse osmosis systems including the 1240 Series, E Series, M Series, Pro Series, HT101, HT102, HT103, and HT123 models. This filter fits Clack Microline compatible housings and serves as the critical second stage of filtration, removing residual chlorine that would otherwise damage the thin-film composite (TFC) RO membrane. It also reduces taste, odor, and fine particulate down to 5 microns, ensuring optimal water quality and maximum membrane lifespan.
💧 Pro Tip: Always replace your carbon block prefilter before it expires. Chlorine breakthrough will degrade your RO membrane rapidly, turning a low-cost filter replacement into an expensive membrane replacement. Mark your calendar for every 6 months to keep your system running efficiently.
