The Inline DI Mixed Bed Deionization Filter (Model K2555-JJ) is designed to produce
deionized, ultra-pure water by removing dissolved ionic contaminants that remain after
reverse osmosis filtration. Filled with high-quality mixed-bed deionization resin, this filter helps reduce
ions such as sodium, calcium, iron, and copper.

This filter is commonly used as a post-RO polishing stage in countertop reverse osmosis
systems and is ideal for applications requiring very low TDS water.

🔧Installation Tips

▶️ Video Installation Guidance

Because RO systems and plumbing layouts can vary, there are multiple valid ways to install an inline filter.

If you are unsure about your setup, we recommend:

• Searching YouTube for “inline RO filter installation”
• Watching a video that best matches your system type
  (under-sink RO, countertop RO, post-filter installation, etc.)

Visual step-by-step videos can be very helpful and often make installation easier and faster.
