Mine got here a couple of days ago. So I have been checking it out and they really came up with a good idea on this filter.
For canoe trips...........
Been searching the web for there mesh bag so it can be used as a gravity filter on canoe trips. Figured it would be a lot simpler to fill the bag , hang it in camp and let the water flow without doing any work.
The up side is that I would only have to take a one gallon jug and as it was emptied then refill it in camp in place of carrying a gallon of water for each day on the water.
For backpacking , A lot of the back country areas the state has for hikers they have the old fashion pitcher pumps with signs on them that the water needs to be treated and this filter should do the job. Have the water from a couple of the Nalgene bottles to drink between camps and then in camp fill the bag and filter the water in to the Nalgene bottles.
After a trip the maintenance on the filter is really simple , Back flush the filter. Then put a cup of bleach in the bag that was used and top it off with water. Run some of this mix threw the filter , let it sit for an hour , empty it and let it dry. It could not be any simpler.
I plan on putting it and the bags in a gallon zip lock and roiling it to get a lot of the air out for when it is being packed on trips. If luck smiles on me I might be able to locate a small stuff sack for it , if not then I may break out a needle and some thread and make one. But still in the zip lock since I am not sure how much water will stay in the filter after it has been used a couple of times. I don't want anything leaking on the stuff in the back pack even with everything in waterproof stuff sacks.
Over all I really like it , it is simple to use , packs up nice and small , simple to clean and weighs next to nothing. Plus according to them it will furnish a lot of filtered water.
