Buying Guide: Cheap but Effective
Keep these points in mind before you buy.
Pore size matters
CDC says a filter with an absolute pore size of 0.3 micron or smaller removes bacteria and parasites, but not viruses.
Squeeze, straw, gravity or purifier
Straws are simplest, squeeze filters are flexible, gravity filters serve groups and purifier bottles target viruses too.
Skip what you do not need
Solo hikers rarely need gravity bags; families and groups do.
Budget Tips
Safe water for less:
- Pick 0.1 micron filters.
- Add tablets for backup.
- Clean the filter often.
