Portable water filtration system
Compact filter that removes bacteria and protozoa from sketchy water sources through hollow-fiber or carbon filtration. Turns questionable urban water into safely drinkable liquid for skills practice.
What to look for
- 10.1 micron or smaller filtration (removes bacteria and protozoa)
- 2Filters at least 1,000 liters before replacement
- 3Squeeze bag or straw format that works without pumping
- 4Stated effectiveness against E.coli and Giardia
Skip
- Purification tablets alone (slow, taste bad, and you're learning filtration)
- Filters that only improve taste, not safety
- Gravity systems for urban use (too slow and bulky)
Used for: Practicing emergency water sourcing identification · Testing rainwater collection methods · Urban survival skills training · Backup hydration during long explorations
