How much you save by ditching bottled water.
An average European family throws away €200-300/year on bottled water and generates 1,500 PET bottles. A €60 filter eliminates both. Adjust the sliders and see the real number for your case.
WHO recommendation: 2 L per adult.
Reference: 6 × 1.5 L pack ~€4.5 = €0.50/L in most European supermarkets.

How it's calculated
We estimate filters needed based on total volume (1 filter covers 1,500 L). Net savings = bottled water spend − cost of needed filters.
Based on GoPure filter €59.99 · 1,500 L lifespan · 30 g PET per bottle · 80 g CO₂ per bottle (lifecycle).
The numbers behind the calculation
The real cost of bottled water
€0.30-0.80/L at the supermarket. For a family of 4 with 2 L/day per person, that's 8 L/day = 24 L/week. Over a year: 1,250 L and €300-500 tossed into the checkout line.
The plastic footprint
Each 1.5 L bottle weighs about 30 g of PET. An average family discards 830 bottles per year = 25 kg of plastic. Over 5 years: 125 kg. Only 30% is actually recycled in Europe.
The invisible CO₂
Each bottle has a ~80 g CO₂ footprint from manufacturing, transport from spring, and refrigeration. Average family: 66 kg CO₂/year just from water.
When the filter does NOT save
If you live in a hard-water area and don't filter at all, there's no saving (you spend nothing). But the filter still improves taste and covers you when traveling.
