DIY Water Filter
A field filter clears sediment and improves taste — but it does NOT make water microbiologically safe by itself.
A note of discernment
A common dangerous myth: a sand-and-charcoal filter does NOT kill germs. Treat the water afterward — clear is not the same as safe.
What to do
- 1Layer (top to bottom) in a bottle/cloth: cloth, then fine sand, then coarse sand, then charcoal, then gravel.
- 2Pour cloudy water through; it comes out clearer and better-tasting.
- 3ALWAYS finish by boiling, using a rated filter, or chemical treatment to kill pathogens.
- 4Use crushed charcoal from a clean wood fire (not briquettes) for odor/taste.

- Believing DIY filtering makes water safe to drink
- Using barbecue briquettes (chemicals)
