Has anyone used this filter yet? http://www.renovowater.com/products/renovo-trio
I became intrigued after reading the review on Stick's Blog (http://sticksblog.com/2014/03/22/first-look-the-renovo-water-filter/). It filters down to 0.05 microns, which will filter some heavy metals and chemicals (pesticides). I hike a lot in the Washington DC suburbs and have been very hesitant about filtering from suburban streams with my Sawyer mini in densely populated areas due to the possible chemical contamination, so I end up just packing all my water for dayhiking (which is a serious drag on high heat/humidity days).
The Trio weighs more than the mini (3.5 oz) but a lot less than an extra liter or two of water. ;-) More expensive to maintain than the Mini as well due to replaceable filters, but may well be worth it in more suburban/urban environments.
