Katadyn Vario Dual Technology MicroFilter

Katadyn's lightweight Vario Dual Technology MicroFilter adjusts for dirty water or normal water conditions, so you get the cleanest, freshest water possible no matter where you're backpacking. A simple turn engages the ceramic prefilter when you're pumping out of a muddy lake so the pleated glass-fiber filter inside doesn't get destroyed. After a long, hard hike, this Katadyn water filter's dual piston pump works smoothly and easily—pumping out up to 2-liters per minute. The Vario Dual Technology Filter removes waterborne bacteria so you can drink safely on your camping trips, and uses a replaceable carbon core and cleanable ceramic disc. Attach Katadyn's adaptor base directly to your standard Nalgene water bottle opening, or use the output hose for larger water containers.
