Great filter but it may not be what you are looking for.

Disclaimer: Don't buy this filter if you plan to use it primarily for more than two people.

I use this on solo backpacking trips and it works great as long as you know how to use it. The pump must be backflushed FREQUENTLY in order for it to work well consistently. A lot of people give this filter a bad rap but they have most likely had bad experiences because they got the wrong filter for the job. I love my microfilter. It is light and pumps really quickly (although you do have to take into consideration all the time you must spend maintaining the filter). My only complaint is that screw top for nalgenes/hydromedary bags leaks a bit. As long as you hold the nalgene or hydromedary completely upright while pumping into it through the accessory top you should not have a problem. However, this is much more difficult to pull off with a hydromedary bag.
