Water filter at your hostel
If there is something no one can live without, it’s water. However, there are many places where we cannot drink the water directly from the tap. One solution to this is to use water filters connected to the water pipes or directly to the tap. What a better way to contribute to a better environment than having a water filter at your hostel? There are many good water filters on the market and this is an investment for both your hostel, the tourists and the environment.
Another good idea is to not sell bottled water, but instead sell for example reusable bottles with your hostel logo. It is a good way to market your hostel as well as doing something good for the environment. This could also be a cool souvenir for the guests at your hostel.
