My granddaughter (23 ) loves travelling. She has already trekked through the High Andes to Machu Picau and two years ago joined a young persons camping tour from San Francisco to New Orleans. This trip covered stays in various of your National Parks, etc. She is most definitely a fan of your fabulous Country and has plans for more tours, treks, etc.across the USA.
Unfortunately she was diagnosed with a severe case of Ulcerative Colitis, an autoimmune disease, after her San Francisco/New Orleans trip. She picked up the ecoli bug and spent a night in hospital in Flagstaff, where she received excellent treatment. However on her return to the UK she was hospitalised and it was then they diagnosed Ulcerative Colitis. That was two years ago now and her condition has since been stabilised ( although is always subject to flare ups) and already is planning a trip later this year, but she has to be very careful with her health, especially drinking clean safe water on any trekking trips.
I am very much aware that backpacking and trekking in the great outdoors is very much a part of life in the USA, so I think you guys are the experts. I would like to buy her a water filtration system that is easy to carry/operate and minimises as many risks as possible. I have looked online but am confused by the variety of products available. However one system that does interest me is the Sawyer Mini Filtration System - https://sawyer.com/products/mini-filter/
I would welcome any comments on this, or recommendation of any other suitable water filtration systems.
Thanks for your help
