Description
4-in-1 Remineralization Filter Cartridge
Restore the natural balance of your water. Our 4-in-1 cartridge is specifically designed to follow Reverse Osmosis filtration, re-introducing essential minerals and raising the pH level to an optimal 7.5–8.2.
Key Benefits:
- Restores soluble minerals: Calcium, Magnesium, Sodium, Potassium, and more.
- Increases dissolved oxygen levels for better cellular hydration.
- Reduces “water clustering” for faster absorption.
- Neutralizes body acidity by balancing pH levels.
Advanced 4-Stage Mineral Media:
1. Tourmaline (“Magic Stone”)
A semi-precious gemstone that aids detoxification, reduces stress, and boosts mental alertness by releasing negative ions and Far Infrared Rays (FIR).
2. Maifan Stone Balls
Highly absorptive media known for removing heavy metals while releasing essential iron, zinc, and selenium into the water.
3. Bioceramic Infrared Media
The perfect source of FIR energy to activate water molecules and improve oxygen levels throughout the body.
4. Alkaline/Mineral Media
Specially formulated to provide the final pH boost and ensure a rich blend of 15+ essential minerals are present in every drop.

The Science of Negative Ions
Research by Dr. M. Terman of Columbia University highlights that negative ions—like those generated by Tourmaline—can significantly improve mood and relieve seasonal depression. These “vitamins of the air” provide the same refreshing feeling as standing near a waterfall or a spring thunderstorm, helping to heal and soothe the body naturally.
🔧Installation Tips
Tubing Size
- Most RO systems use 1/4″ OD tubing (standard RO size).
- Some countertop RO systems and specialty setups use 3/8″ OD tubing.
- Tubing size refers to the outside diameter (OD) of the tube.
When Do You Need Elbow Adapters?
- Select 3/8″ OD Tubing if your system uses larger tubing.
- We include 2 elbow adapters to connect the inline filter to 3/8″ OD tubing.
✔ No tools required
✔ Push-to-connect installation
When Do You Need a T-Fitting?
A T-fitting (1/4″ stem x 1/4″ OD Tubing x 1/4″ OD Tubing) is helpful if you are:
- Adding the inline filter to an existing 1/4″ RO line
- Want an easier install with a clean branch connection
- Installing between tubing lines without reworking your layout
✔ Optional accessory
✔ Makes installation easier for some setups
Not Sure Which Option to Choose?
- If unsure, select Universal Fit option (Included 4 elbow adapters for 1/4″ & 3/8″ OD Tubing Connection).
- Message us before ordering—we’re happy to 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.
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.
