Our Best Water Filters Remove Micro-Organisms and Bacteria
Approved by the U.S. government and registered by the EPA

The only filter that always stops germs, parasites, cysts and bacteria. Protects you from typhoid, dysentery, cholera and giardiasis (known as "traveler’s diarrhea").
Never passes untreated water-An enclosed caliper (measuring device) lets you know when element needs to be replaced. Water flow lessens when it’s time to clean the element. When it plugs, just brush it off and re-use! Competing filters let contaminated water reach your cup as they age. Won’t crack like cheap imitations.
No chemicals-Disease causing germs and cysts can’t get past the filter’s microscopic (.2 micron) pores. Self-sterilizing; silver granules hermetically sealed in the filter core positively prevent bacteria growth and mold. Doesn’t add to, detract from, or change make-up of water. No chlorine, iodine or other caustic chemicals!
EPA Registered-Removes 100% of algae, suspended contaminants and bacteria. Used by NATO, International Red Cross, and Wycliffe Bible Translators. Tested and praised by the U.S. Testing Company in New Jersey and Harvard University Department of Applied Sciences.
