Frequently Asked Questions

Does this system work in developing countries where viruses are common?

Yes. The combination of ceramic/carbon filtration and Aquatabs purification tablets provides comprehensive protection against viruses, bacteria, and protozoa commonly found in developing countries and popular wilderness areas.

How do you clean the filter element in the field?

The ceramic element can be cleaned repeatedly using the included cleaning pad. No tools are required, and cleaning restores full flow rate for continued use.

What makes this different from iodine-based purification systems?

The Aquatabs tablets use chlorine-based chemistry instead of iodine, eliminating the harsh metallic taste associated with iodine while providing effective viral protection.

Does this meet official water purification standards?

Yes. This system meets U.S. EPA Guide Standard and Protocol for Testing Microbiological Purifiers and NSF protocol P231 testing standard for comprehensive water treatment.
