Hello, Great website, with much useful information! My plan is to go cycling and wildlife/birdwatching through everywhere in South-East Asia for more than a year, in Indo-China, Phillipines, Indonesia, etc. The dream is to end up in Papua New-Guinea. While cycling in hot weather I drink about 10 liters of water a day. I don’t want to, and in many remote places I wouldn’t even be able to, buy water bottles for all of that. In Europe (and Georgia, Caucasus, where I’m now traveling) I can use my loyal Sawyer Squeeze filter and filter unlimited amounts of water everywhere, both through a big gravity system or squeezing by hand. But unfortuntely, the Sawyer Squeeze doesn’t filter viruses out of the water, so it’s only a partial solution for South-East Asia. I don’t know whether it’s possible to buy chlorine dioxide pills/ liquid in many places in South-East Asia and I don’t want to lug around too much. I also don’t like the chemical taste and don’t know whether it’s healthy to use in large quantities for extended periods of time. I could buy a Steripen, but you can treat only one liter of water at a time, you would have to filter the water anyway, and you need to bring multiple spare batteries and possibly another light bulb. My main options for now are the pumps Survivor Filter Pro X and MSR Guardian, or electrified chemical purifiers Aqua Research H2gO Prime and the Potable Aqua Pure. The Survivor Filter Pro X seems awesome. It produces very clean (0.01 main filter) and tasty (carbon filter) water without effort (electronic). The downsides are that it is fairly bulky and heavy and, I’ll need one or two carbon filters and, most importantly, that it’s an electronic device and I’m a bit hesistant in placing all my trust for clean water for a year into that. A good option would be to order the manual convertion kit with it. So that, if something happens, you can still manually pump. But it will add even more to the weight and bulkiness of the set-up and the flow rate for manually pumping is really low (0.5 l per minute), which means 20 minutes of pumping for ten liters. So, I wouldn’t want to do that for extended periods. An alternative would be the MSR Guardian, which is a fully manual pump with an exceptional flow rate of 2.5 l per minute. The downsides are that is is even bulkier and heavier than the Survivor Pro X (without the manual back-up kit), that is has only a 0.02 main filter (compared to 0.01 for the Survivor) and that it is super expensive (almost 400 dollars). It also does not have a carbon filter, so the water will taste less good. Furthermore, there are reports of the pump breaking, which could be a potential disaster and unexceptional for a pump with a price like that. In either case, I might still bring my Sawyer squeeze filter, combined with chemical drops, as a back-up system. On the other side are the chemical purifiers Aqua Research H2gO Prime and the Potable Aqua Pure. I couldn’t really find a difference between those two. The upsides are that they are lightweight, you only need salt and that it is easy to pair them with my existing Sawyer Squeeze filtration system. The downsides are that it is chemical, so it makes the water taste less good (although better than usual pills). And from a health perspective I also don’t want to drink a lot of chemically-treated water for a year straight. I’m still researching and hesitating a lot. I’ll have to make a decision soon, since I’ll be leaving Georgia, Caucasus, in a month and will travel to Thailand afterwards. So, there’s only one more month to let a device ship (from potentially the US) to Tbilisi. Thanks for any help/suggestions! Michaël
