Katadyn® Vario Dual-Tech Filter sifts the "uglies" out so you can drink clean, fresh water in the field.
The Vario cleans up dirty river and stream water for drinking... a simple turn of the multi-stage filtration system configures the filter for maximum effectiveness.
Produces up to 2 quarts of water per minute in "faster flow" setting, and up to 1 quart per minute in "longer life" mode that saves your 0.3 micron filter. Comes with a replaceable carbon cor to keep your water tasting fresh. Reduces chemicals, odors and toxins through the life of the cartridge. A great buy for the adventurous type... keeps you close to hydration, no matter where you roam.
