Genny requires only a minute of installation. Genny can even filtrate the highly polluted water to provide clean and fresh drinking water. It requires maintenance once a year and the maintenance cost is relatively so much cheap. The water flowing is also great. You can fill up 2 litres bottle in just a minute. Beside providing the fresh water from air, during the process, it can even purify the room's air. That's make it a perfect device to be used in place with high pollution. Those products should be used in disastrous zone and refugeees shelter where people are living being congested and unhealthy. Incredible!!!
