When you buy one of the tariffs (Monthly, Yearly or Yearly with Bottle), you not only contribute to the maintenance and operation of the network, but you also help to build new filtration venues.

Every year we would like to save about 200,000 tons of plastic in the Czech Republic. In order to reach our aim, we need to have installed 1000 new devices by the year of 2025 and this cannot be done without your help.

Thank you for creating the world without unnecessary plastic with us!
