Product Summary

The SteriPEN Classic 3
When camping, hiking, backpacking, or traveling, the SteriPEN Classic 3 with Pre-Filter is the perfect pack to keep you safely hydrated. The Classic 3's UV light destroys over 99.9% of waterborne microorganisms that cause illness. One set of four alkaline batteries treats 100 half-liters or 50 full liters of water. Supercharge your SteriPEN with a set of lithium batteries and treat up to 150 liters; you can also use NiMH batteries. The Classic 3's enhanced LED indicator panel lets you know treatment size and status of batteries and UV lamp. It's also sleek and ergonomic with an easy-to-remove, twist-off lamp cover.

Easy to Use
Like all SteriPENs, the Classic 3 is simple to use: remove the lamp cover, press the activation button, submerge in water, and stir. In 48 seconds you have a half-liter of safe drinking water, or purify a full liter in 90 seconds.

The 4040 micron screen Pre-Filter fits perfectly on wide-mouth, one liter water bottles and removes particulates that can get in the way of UV light in water. The Pre-Filter is designed to be stored directly on a wide mouth bottle, and the SteriPEN Classic 3 fits perfectly in the filter. Just insert the Classic 3 in the filter opening, turn the bottle upside down, and gently rock to circulate light throughout the bottle. The tapered end also fits snugly in plastic water bottles. Just insert the lamp into the water bottle, turn it upside down and gently rock the bottle.

The Bundle Pack includes the SteriPEN Classic 3, carrying case, Pre-Filter, and user's guide. Weight: 2.9 oz. Dimensions: 7.3" x 1.7" x 1.7". Lamp life: 8,000 activations. Minimum bottle diameter: 0.8". Comes with a 3-year limited warranty.
