Filter Kit FK-108 for Vertex Water Coolers (Reverse Osmosis)

FK-108 Filter Kit delivers multi-stage reverse osmosis purification for Vertex water coolers, providing premium-quality drinking water free from dissolved solids, chlorine, and contaminants. Designed for easy maintenance and superior performance, this kit keeps your RO cooler operating at peak efficiency.

Overview

The FK-108 is the replacement filter kit for RO models such as the PWC-3500R, PWC-1500R, and PWC-1000TR. It combines sediment, carbon, and RO filtration stages to remove impurities down to the molecular level—ideal for offices, healthcare environments, and homes that demand the purest water possible.

Includes all pre- and post-filters required for one full maintenance cycle. The RO membrane (50–75 GPD) may be replaced less frequently depending on usage and feed water quality.
