Additionally, the filter cartridge is marked with a large blue flow arrow and color-coded connectors to designate dirty and clean ends.

The drawback to water filters is that the microscopic holes in their filter media are still too large to catch viruses.

Iodine and chlorine dioxide drops are lightweight and kill many harmful bacteria, protozoa, and viruses, but require 20-30 minutes before drinking and frequently impart an unpleasant aftertaste. Boiling is safest, but takes a lot of fuel and time, which is especially inconvenient mid-day and makes hot water unpleasant to drink during warm weather. When it comes to purifying water, there are many helpful methods: boiling, chemical treatments like iodine tabs and chlorine drops, and ultraviolet light.
