Prepper water filters need to match the job: squeeze/straw for movement, gravity for base, and chemical backup when water is dirty or cold. Capacity claims mean nothing if you won't carry or maintain the system.
Written by Mike, a union power lineman with 22 years on the job and mutual aid plus storm restoration deployments after Sandy, California wildfires, Texas winter storms, and Gulf Coast hurricanes.
LifeStraw is simple drink-through for streams. Sawyer Squeeze is more versatile (bottles, inline, bags) for group and longer trips. Many kits carry both roles covered somehow — filter plus chemical backup.
Yes. Filters need source water. Store gallons for home; use filters when moving or when stored water runs out.
FEMA baseline is 1 gallon per person per day minimum; serious plans run closer to 2 gallons when cooking and sanitation count. Use the free water storage calculator for household size and duration.
