parry / Sharing water purifier


It is not easy to drink clean water when going for a walk in the park, hiking, or camping. "Parry" is a portable water purifier. Put dirty water in the cup and press power on the lid to make it clean. You can also use the mobile phone application to rent and return any place where the rental machine is installed. A mobile phone application is used to find a rental machine that is close to the current location, pay for it, and then rent it. Return is a connected method. You can continue to connect other water purifiers and return them indefinitely.
