Water is the category where bad assumptions hurt fastest.
If your household has plenty of gadgets but no clear water plan, the priorities are upside down.
You need both:
- stored water you can use immediately
- a backup method to treat or filter more
Storage vs filtration
Storage solves immediate disruption. Filtration solves resupply. They are not the same problem, and treating them like one usually leads to thin coverage in both.
Good backup layers
- bottled or filled container storage
- gravity filter for household use
- portable filter for movement or travel
- purification tablets as a fallback
Pick by scenario
A large household with shelter-in-place plans needs something different from a person building a compact go-bag.
The boring truth
A reliable, simple filter you maintain is better than a complicated premium system you never test.
