Finally, field water disinfection has become lighter. Never did I notice the bulk and serious weight of water filter more than when I had to pack for a week in rural Haiti. In my Patagonia MLC pack I had just enough room for a Sawyer water filter bottle, a Cocoon travel sheet, and a stash of medical gear. Nothing else.
Here are two new purifiers that would have given me some spare room in my pack.
Traditional filters with 4 micron pores remove protozoa and bacteria, but tiny viruses are small enough to escape capture. Check out Katadyn's MyBottle, with 3-stage ViruStat purification technology including 0.3 micron microfilter, iodinated virus-toxic resin, and a carbon filter to remove bad taste. The best part? You get all this in a bike-cage-compatible water bottle.听
In October, Sawyer鈥檚 already proven squeeze filter system will get upgrade to a 0.02 micron viral filter. And it will clock in at about 6 ounces鈥攁 boon for us weight weenies.
