Description
Four natural mineral media for a smoother, gently balanced finish to RO water
This 3/8″ quick-connect cartridge is the last stage after reverse osmosis. Four media — FIR ceramic, coral red stone, maifan stone and bioceramic balls — contribute trace minerals as water passes through and lift pH from the mildly acidic range fresh RO produces to a near-neutral 7.5–8.3. Not aggressively alkaline. Just water that tastes like water again.
What this media is designed to do
Gentle pH LiftTargets approximately pH 7.5–8.3 rather than strong alkalization.
Four-Media BlendFIR ceramic, coral red stone, maifan stone and bioceramic media.
Trace MineralsContributes calcium, magnesium, potassium and other trace minerals.
Direct 3/8″ QCBuilt-in push-to-connect ports — no adapters, no reducers, no fuss.
Mineral balance without going strongly alkaline
Four-Natural-Media Remineralization Blend — Inside the cartridge are four selected mineral media: FIR ceramic, coral red stone, maifan stone and bioceramic balls. As purified water passes through, the media gradually contributes calcium, magnesium, potassium and other trace minerals, restoring some of the natural mineral character reverse osmosis removes.
The result is a smoother, fuller, more natural taste with a gently balanced, near-neutral pH rather than strongly alkaline water — a good choice if you like the purity of RO but not the flat mouthfeel that comes with it.
- 4 Natural Mineral Media — FIR ceramic, coral red stone, maifan stone and bioceramic media.
- Restores Mineral Character — Adds selected trace minerals back to low-TDS RO water.
- Smoother, More Natural Taste — Mineral conditioning reduces the flat taste of highly purified water.
- Gentle pH Balance — Mild remineralization without making the water strongly alkaline.
- Ideal Final RO Stage — Mineral conditioning after the membrane has completed the primary purification.
