To make a rough estimate, let's assume a family of four consumes 8 bottles of water per day.
Annual Cost of Bottled Water: 8 bottles/day * 365 days/year * €1.50/bottle = €4,380 per year.
Now, let's consider the cost of a water filter system. If we assume a mid-range system costing €200 with replacement filters costing €50 every 6 months:
Annual Cost of Water Filter: €200 (initial cost) + 2 * €50 (filters) = €300 per year.
Savings:
Potential Savings: €4,380 (bottled water) - €300 (water filter) = €4,080 per year.
Note:
These are rough estimates, and actual savings may vary depending on factors like water consumption, filter type, and specific water filter and bottled water prices.
The long-term savings from a water filter can be substantial, especially for larger families or those who consume a lot of bottled water.
Additionally, using a water filter contributes to environmental sustainability by reducing plastic waste.
