"In preparing for our 20 day trek through the Himalayas (Everest Base Camp and Gokyo Lakes), we did exhaustive research to find the best quality water purification system currently available. It had to be effective against all common pathogens, including Giardia and Cryptosporidium, simple to use and very light and compact. Being tasteless and odorless was a high priority, too, as high altitude trekking requires a high rate of water consumption, so the nicer the water tastes, the better.
Pumps and filters are bulky, expensive and make water purification a very time consuming process, so they were discarded as an option. After a hard day on the trail, the last thing you feel like doing is pumping water through a filter. On the trek, people with pumps and filters were first to show interest in what we were using for our water treatment system!
Bottled water is an expensive option, especially at high altitude. There is no recycling program in place in the Everest region, so the use of bottled water is not environmentally sound.
Relying on a supply of boiled water is a risk as you cannot always ensure that the water supplied by a tea house or lodge has been properly boiled.
Sometimes, they even run out of boiled water! Also, boiled water is not a viable option if you require water from rivers or streams while on the trail.
Pristine water treatment having met all of our criteria was selected as our one and only water purification system for the trek and it performed flawlessly. We highly recommend Pristine to any traveler requiring a highly effective, compact and easy to use water purification system."
