How to Make a DIY Water Filter at Home
Clean water = essential for survival.
But what if you’re outdoors or in an emergency with no clean water?

Build your own DIY water filter using simple materials!
What You’ll Need:
1 plastic bottle (cut in half)
Rocks (small & medium)
Coarse sand
Crushed charcoal (activated is best!)
Fine sand
A clean cloth or coffee filter
Contaminated water
Step-by-Step Guide:
1. Prep the Bottle
Cut a plastic bottle and turn it upside down.
2. Add a Cloth Layer
Place cloth over the neck—acts as the last filter layer.
3. Fine Sand
Add a layer to catch small particles.
4. Charcoal
Crushed charcoal removes toxins, chemicals, and smells.
5. Coarse Sand
Helps filter out medium debris.
6. Rocks
Catch large particles like leaves and dirt.
How It Filters Water:
Water moves through each layer:
Rocks trap large debris
Coarse sand filters mid-sized particles
Charcoal absorbs chemicals & bacteria
Fine sand catches tiny particles
Cloth ensures clean, sediment-free water
By the end, the water is much cleaner and safer!
Important Reminder:
This filter improves water quality—but doesn’t fully purify it!
Boil the water or use purification tablets before drinking! ![]()
