HOUSE OF KAIROS · WATER
Living
water.
Water is the quiet foundation of everything we do — from the first glass at reception to recovery, hydration, and the pool. Every drop served at House of Kairos passes through a multi-stage filtration system and is independently tested by an accredited public-health laboratory. We publish those results here, in full, and update them with each test.

Independent testing
Samples are collected at the point of use and analysed by Laboratorium Kesehatan Masyarakat Udayana in Denpasar, Bali. Results are assessed against the Indonesian national drinking-water standard, Permenkes RI No. 492/Menkes/Per/IV/2010. Report reference: 290/UDY/VII/2026.
Physical & chemical results.
Twenty-three physical and chemical parameters were measured on the filtered water. Every result sits comfortably within — and in most cases far below — the maximum permitted level.
| Parameter | Unit | Result | Max Permitted | Status |
|---|---|---|---|---|
| Odour | — | Odourless | Odourless | Pass |
| Colour | TCU | 6.0 | 15 | Within limit |
| Total Dissolved Solids TDS | mg/L | 44.8 | 500 | Within limit |
| Turbidity | NTU | 0.32 | 5 | Within limit |
| Taste | — | Tasteless | Tasteless | Pass |
| Temperature | °C | 23.0 | Air temp ±3 | Within limit |
| Parameter | Unit | Result | Max Permitted | Status |
|---|---|---|---|---|
| Iron Fe | mg/L | 0.01 | 0.3 | Within limit |
| Hardness as CaCO₃ | mg/L | 14.02 | 500 | Within limit |
| Chloride Cl | mg/L | 12.12 | 250 | Within limit |
| Manganese Mn | mg/L | <0.01 | 0.4 | Within limit |
| pH | — | 6.5 | 6.5 – 8.5 | Within limit |

| Ammonia NH₃ | mg/L | 0.36 | 1.5 | Within limit |
| Fluoride F | mg/L | 0.28 | 1.5 | Within limit |
| Chromium Cr⁶⁺ | mg/L | <0.02 | 0.05 | Within limit |
| Nitrite as NO₂-N | mg/L | 0.001 | 3 | Within limit |
| Nitrate as NO₃-N | mg/L | 0.008 | 50 | Within limit |
| Cyanide CN | mg/L | <0.05 | 0.07 | Within limit |
| Detergent | mg/L | <0.05 | 0.5 | Within limit |
| Organic Matter KMnO₄ | mg/L | 3.20 | 10 | Within limit |
“Not detected” means the substance was below the laboratory’s detection threshold. Values shown as “<” fall below the smallest amount the method can reliably quantify.
Microbiological results.
Bacteriological testing (MPN method) confirmed the absence of coliform bacteria and E. coli — the two indicators that matter most for drinking-water safety.
| Parameter | Unit | Result | Max Permitted | Status |
|---|---|---|---|---|
| Total Coliform | MPN/100 mL | 0 | 0 | Not detected |
| E. coli | /100 mL | 0 | 0 | Not detected |
| pH | — | 6.5 | 6.5 – 8.5 | Within limit |
| Residual Chlorine Cl₂ | mg/L | <0.01 | — | Pass |
Laboratory verdict: Good (Baik). Samples taken and examined 6 July 2026.
