Product Features

EFFECTIVE PRE-FILTRATION FOR RO SYSTEMS: The CFII filter cartridge intercepts larger particles such as dirt, rust, and deposits, preventing blockages and improving overall filtration performance.

PROTECTS YOUR RO MEMBRANE: Designed as a durable first-stage filter, it significantly reduces the load on the RO membrane, helping extend the lifespan of your entire system.

HIGH-CAPACITY SEDIMENT REMOVAL: Efficiently filters out visible contaminants to ensure cleaner, clearer water and smoother downstream water flow.

LONG-LASTING 6–12 MONTH LIFESPAN: Depending on water quality and usage, each CFII filter provides reliable filtration for 6 to 12 months, reducing the frequency of replacements.

EASY REPLACEMENT & UNIVERSAL FIT: Quick-change design allows for simple installation and replacement, compatible with most standard RO systems using CFII pre-filter cartridges.
