Survival Skills: How to Filter Water Using Charcoal
Hey there, and welcome! Gary here with the Concealed Carry Academy, back with episode 11 of our Odd Survival Skills series. Today, we’re tackling one of the most critical survival challenges: obtaining clean water in the wild when you don’t have a commercial filter. In this episode, we’ll explore how to use charcoal as a natural water filter, an essential skill that can make all the difference in a survival situation.
The Importance of Clean Water
Water is essential for life, and in a survival scenario, having access to clean, drinkable water is a top priority. Without it, dehydration can set in quickly, leading to severe health issues and decreased decision-making ability. Contaminated water can contain harmful bacteria, viruses, and parasites, so knowing how to filter and purify water is a must-have skill for anyone venturing into the wild.
Recommended Gear for Water Purification:
- LifeStraw Personal Water Filter: Lightweight and easy to carry, perfect for emergencies.
- Potable Aqua Water Purification Tablets: A simple and effective way to purify water on the go.
Using Charcoal as a Natural Water Filter
If you don’t have a commercial water filter on hand, don’t panic. You can create a simple, effective water filter using materials readily available in nature. Charcoal, with its natural filtering properties, is a lifesaver when clean water is scarce.
Step 1: Make or Gather Charcoal
- Start by finding burnt wood from a campfire or create your own by burning wood until it turns black and crumbly.
- Crush the burnt wood into small pieces to create the charcoal needed for filtering.
Step 2: Build Your Filter Layers
- Find a container, such as a hollowed-out piece of wood, a plastic bottle (if available), or even bark.
- Layer the container with crushed charcoal, followed by sand and gravel.
How the Layers Work:
- Charcoal: Traps impurities and chemicals.
- Sand: Removes smaller particles.
- Gravel: Filters out larger debris.
Pro Tip: Use a Collapsible Survival Bucket for easier water collection and filtration.
Step 3: Filter the Water
- Pour the water slowly through the layers of your homemade filter.
- Collect the filtered water in a clean container.
Important Reminder: While this method improves clarity and removes debris, it doesn’t eliminate all bacteria or pathogens. Always follow up by boiling or chemically treating the water to ensure it’s safe for drinking.
Why Charcoal Works as a Filter
Charcoal’s effectiveness lies in its porous structure and large surface area, which allows it to:
- Trap dirt, debris, and impurities.
- Absorb certain chemicals and improve water’s taste.
This natural filtering ability makes charcoal an invaluable resource for survival. With minimal materials, you can turn murky, unsafe water into a drinkable resource.
Additional Tips for Finding and Filtering Water
1. Locate Water Sources
- Look for running water in streams or rivers, which is less likely to be stagnant and contaminated.
- Collect rainwater if possible—it’s naturally clean and easy to gather.
2. Use Natural Filters
- Moss, sand, and even cloth can act as basic pre-filters to remove larger debris.
3. Purify Your Water
- Boil: Heat water to a rolling boil for at least one minute to kill bacteria and parasites.
- Chemical Treatment: Use iodine tablets or drops if available to further purify the water.
4. Avoid Contaminated Water
- Stay away from stagnant pools or water with obvious signs of contamination, such as foul odors, algae, or dead animals nearby.
The Rule of Three: Prioritizing Survival Needs
When you’re in a survival situation, remember the Rule of Three:
- 3 minutes without air.
- 3 hours in extreme weather without shelter.
- 3 days without water.
- 3 weeks without food.
Accessing clean water should always be one of your first priorities.
Practicing Water Filtering Techniques
Like any survival skill, practice makes perfect. Take time to experiment with building and using a charcoal water filter in a controlled environment before heading into the wild. Familiarize yourself with:
- Crushing charcoal efficiently.
- Layering materials correctly.
- Testing the clarity of filtered water.
By honing your skills beforehand, you’ll be better prepared to act confidently in a real emergency.
Final Thoughts: The Power of Knowledge in Survival
Clean water is the foundation of survival, and knowing how to filter water using charcoal is a skill that can save your life. While this method is effective in removing debris and some impurities, always boil or chemically treat water afterward to ensure it’s completely safe for drinking.
