Description

4-in-1 Remineralization Filter Cartridge

This post-filter is designed to slightly raise pH levels to approximately 7.5–8.2 and restore essential minerals removed during the reverse osmosis process. It contains four types of high-quality natural mineral media:

  • Tourmaline stone

  • Bioceramic infrared media

  • Maifan stone

  • Alkaline and calcite blend

These elements work together to enrich purified water with dissolved oxygen and release vital minerals such as Calcium, Magnesium, Sodium, Potassium (K), Phosphorus (P), Zinc (Zn) and more—helping to rebalance and revitalize your drinking water.


Tourmaline Media

Tourmaline, also known as the “Magic Stone,” is a semi-precious mineral renowned for its detoxification and health benefits. It helps relieve stress, improve circulation, boost immunity, and enhance mental clarity. It also emits Far Infrared Rays (FIR) and negative ions, which gently heal, stimulate, and detox the body.

FIR waves can penetrate deeply into the body, reaching tissue, muscles, and bones. According to Dr. M. Terman of Columbia University, negative ions—like those produced by tourmaline—can significantly improve mood and energy levels, with studies showing benefits comparable to antidepressants, but without side effects.

Additional benefits include:
– Reduction of water molecule clustering
– Activation of water molecules, enhancing hydration
– Improved oxygen levels in the body
– Release of over 15 trace minerals, including SiO₂, K₂O, CaO, Na₂O, and MgO

Maifan Stone Media

Maifan stone is highly absorbent and effective at removing heavy metals and contaminants. It also replenishes the water with essential minerals like Calcium, Iron, Zinc, Magnesium, and Selenium.


Bioceramic Infrared Media

A powerful source of Far Infrared Rays (FIR) and negative ions, this media helps improve circulation, boost cellular activity, and promote natural detoxification.


Alkaline & Calcite Mineral Media

This blend helps neutralize acidity and gently boosts the pH level while releasing additional minerals for taste and health support.

Installation Tips

Tubing & Quick-Connect Notes

  • Common RO tubing sizes are 1/4″ OD and 3/8″ OD.
  • Cut tubing with a clean, straight 90° cut for the best seal.
  • Push tubing fully into the fitting until it stops, then pull back gently to confirm it locks.

Important Use Notes

  • Use with cold water only.
  • For best performance, install as the final stage after the RO membrane.

Not Sure Which Option to Choose?

    • If unsure, select Universal Fit (includes 4 elbow adapters for 1/4″ & 3/8″ OD Tubing Connection)
    • Message us before ordering—we’ll help you pick the right fittings.

▶️ Video Installation Guidance

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

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

Visual step-by-step videos can make installation easier and faster.

    I added this 4-in-1 remineralization filter as the final stage to my countertop RO system, and the difference was noticeable right away. The water now tastes smoother and more refreshing, with a slightly alkaline feel that I love. I tested it after a few days of use and got a nice boost in pH and mineral content. I appreciate that it combines tourmaline, FIR media, and maifan stone all in one—very convenient and cost-effective. Highly recommend for anyone who wants to restore healthy minerals to their purified water
