Side-by-Side Impact
| Impact Area | Tallinn | Moscow |
|---|---|---|
| Limescale buildup | Minimal | Moderate — monthly descaling |
| Boiler/heating risk | Low risk | Monitor annually |
| Dishwasher salt setting | Low setting (1–2) | High salt setting (3–5) |
| Skin & hair impact | Low risk | Low risk |
| Detergent usage | Standard dose | +15–25% more |
Key Findings
Hardness Difference: 40 mg/L
Moscow is meaningfully harder than Tallinn. Residents moving between these cities should adjust dishwasher salt settings, descaling frequency, and boiler service schedules.
