Thanks to DELIOS, I was able to produce safe drinking water.

at the top of Mt. Everest

I once sent you an inquiry about the function of your 'Portable Water Filter, DELIOS. Now I would like to thank you for two things:

(1) After my inquiry I received a detailed reply from you (Urban Tech). I appreciate your kind favor and your staff.

(2) This winter, I made a two-month trip to Nepal. I stayed in the Himalayas. I enjoyed a comfortable stay there thanks to DELIOS.

This was my third trip. When I visited there the first time, I suffered from dysentery. On my second trip, I suffered from mountain sickness. People advised me to drink lots of water to avoid mountain sickness. This time, I was able to drink enough water with DELIOS.

In Katmandu, I usually bought bottles of mineral water and put them in some DELIOS vessels whenever I went out. The vessel was just the size for a canteen.

In the Himalayas, they take water from a brook and boil it for drinking water. Boiling water to where it is safe to drink takes a longer time due to a lower boiling point in higher mountains [90°C versus 100°C at sea level].Water taken from brooks contains refuse because of snow-fed streams or melt water. Also, this method requires burning lots of wood. On the other hand, DELIOS has no such troubles and moreover it is an environmentally friendly product.

I trekked farther from the cabin I was staying in up to the top of an unknown mountain, carrying a camera and DELIOS-dipped water from a brook for drinking water. I was thus able to reach the summit, where I took pictures of the whole scenery of Mt. Everest.

When I moved to a town near the border of India, I could not purchase bottled mineral water. The tap water there was not so hygienic, so I could not drink it safely. But thanks to DELIOS, I was able to produce safe drinking water.
