Turn on the tap—does “clear” really equal “safe”?
The World Health Organization’s Guidelines for Drinking-water Quality warn that water with pH below 6.5 is “soft,” aggressive to pipes and can leach lead or cadmium, while prolonged intake below 6.5 or above 9.5 stresses human metabolism.
In short, “purified” ≠ “good.” Truly healthy water must be clean, mildly alkaline and mineral-balanced.
Today we start with a ball only 3 mm in diameter and see how ZONE Long-Lasting Alkaline Balls upgrade ordinary filtered water to village-of-longevity-level, mildly alkaline goodness.

1. The Three-Stage Story of Filter Media: Clean Is Only the Starting Line
Stage 1 – Mechanical barrier: PP fiber and carbon block remove silt and chlorine.
Stage 2 – Fine filtration: RO/UF/NF membranes drive heavy metals and viruses below safety limits.
Stage 3 – Conditioning: Often ignored!
RO product water can dip to pH 5.5, taste flat, and even strip body minerals.
The third stage—conditioning—decides whether water is merely “safe” or genuinely “healthy.”
Alkaline balls are the hidden champions of Stage 3.

2. Three Pain-Points of Common Alkaline Media
Pain-point
Symptom
Root cause
Short life
Alkalinity crashes in 3–6 months
Food-grade CaCO₃ dissolves too fast
Poor taste
Bitter, slippery mouthfeel
Excess OH⁻+Na⁺ pushes pH > 9.5
Clogging & dust
White water, pressure drop
Low-temp sintering, crush strength < 20 N
3. ZONE’s Solution: Turn “Alkali” into a Slow-Release Capsule
Substrate: Maifan-stone + tourmaline composite, 42 % micro-porosity
→ Breaks water into small clusters and boosts dissolution efficiency.
Functional phase: Food-grade calcite CaCO₃ + MgO + ZnO
→ Meets GB 1886.214 food-grade standard; no industrial lime.
Slow-release coating: Low-glass SiO₂-P₂O₅-CaO 0.8 µm layer
→ Ca²⁺, Mg²⁺, OH⁻ diffuse instead of dump.
Sintering: 980 °C rotary kiln, 20 min hold
→ Crush strength ≥ 65 N per ball; no dust after 10 m drop test.

Conclusions
- pH locked in 7.5 ± 0.3 sweet zone.
- Alkalinity loss < 10 %; still above CJ/T 94 requirement (≥ 30 mg L⁻¹).
- Ca²⁺ & Mg²⁺ increments ≤ 12 mg L⁻¹ & 4 mg L⁻¹—no scaling risk.

5. Field Stories: The Ball’s “Daily Shift” in Three Cartridges
A. Undersink RO → post T33
Pain: RO water tastes “scratchy.”
Fix: 100 g ZONE balls (~1/3 of T33 volume).
Result: pH 5.7 → 7.6; user says “like mountain spring.”
B. Portable gravity pitcher
Pain: No alkaline water on trips.
Fix: 50 g balls + 20 g silver-impregnated carbon; total < 100 g.
Result: 600 mL pitcher delivers pH 7.5 in 30 s; no odor for 30 days.
C. Whole-house carbon filter
Pain: Low alkalinity, heater corrosion.
Fix: ∅205 × 380 mm FRP vessel with 5 kg balls after carbon block.
Result: Whole-house pH 7.2–7.8; heater anode life +50 %.

6. FAQ
Q1: Will pH exceed 9?
A: Slow-release caps pH below 8.0; rate auto-drops as throughput rises.
Q2: Scaling like other “alkaline sticks”?
A: Ca²⁺ increment ≤ 12 mg L⁻¹, far below 60 mg L⁻¹ scaling threshold; Si-P glass also inhibits scale.
Q3: Compatible with other media?
A: Yes with carbon, KDF, Ag-carbon. Keep away from strong-acid ion-exchange resin; use mesh bag if mixed.

7. User Guide
Dosage: 50–100 g for post-RO; 1 kg per m³ h⁻¹ for whole-house.
Replacement: When pH < 7.0 or taste turns flat—typically 2–3 yr / 10 000 L.
Regeneration: Rinse with clean water; no acid wash (destroys coating).
Certifications: GB 5749-2022 immersion, SGS heavy-metal leaching, TÜV RoHS and ten-item testing.

At ZONE we believe:
“Clean” is passing grade; “healthy” is full marks.
One tiny alkaline ball runs a 10 000-liter marathon, returning Ca, Mg and Zn the way nature intended—mildly alkaline, sweet, smooth.
If you need a “fill-it-and-forget-it” alkaline media for your next cartridge BOM, add ZONE Long-Lasting Alkaline Balls and bring longevity-village water to every home.
