Never get sick from tainted water again! The affordable and efficient SteriPEN emergency purifies up to 200 half-liter servings of water on just one set of AA lithium batteries. That's more than enough to see your family comfortably through any problem involving unclean water. The SteriPEN Emergeny UV lamp life is 3,000 treatments.
The SteriPEN Emergency fits perfectly into commercial water bottles, forming a seal that lets you keep the water in the original bottle for purification. Just insert the SteriPEN Emergency securely into the mouth of the bottle, turn it upside down, and you have safe drinking water in less than a minute.
SteriPEN Emergency is powered by 4 AA batteries. Battery quality varies greatly by brand. We recommend using only well-known brand name Lithium or Nickel Metal Hydride batteries. Alkaline batteries are not recommended.
