Clay pot filtration uses a natural and effective method to purify water. The clay's porous nature traps impurities while allowing clean water to pass through.

To create this filter, you'll need two unglazed clay pots. One pot should fit inside the other, with a small gap between them. The inner pot should be cleaned thoroughly before use.

Fill the inner pot with dirty water. As the water seeps through the clay, it leaves contaminants behind. Collect the filtered water in the outer pot. This process can take several hours but requires minimal effort.

You can increase effectiveness by adding a layer of sand or charcoal inside the inner pot. This adds extra filtration and removes additional impurities.

Clay pot filtration is excellent for bushcrafting because it doesn't require chemicals or complex setups. It's a low-cost, sustainable method. Keep your pots clean and free of cracks to ensure optimal filtration.

8) Sand and Gravel Filter

One effective bushcraft method to purify water is using a sand and gravel filter. This method involves layering different materials to filter out impurities.

Start by gathering sand, gravel, and a container. If you have access to it, charcoal can also be added for extra filtration.

Create several layers starting with gravel at the bottom. Gradually add finer materials like sand on top. You can use multiple layers of sand and gravel to improve effectiveness. Charcoal, if available, should be sandwiched between sand layers.

Pour the contaminated water slowly over the top of the filter. The water will pass through the sand and gravel, which will trap dirt and particles.

This method removes physical impurities and some pathogens, making the water much safer to drink. Filtering water through sand and gravel is relatively straightforward and can be accomplished with natural materials found in most environments.

9) Plant-based filtration

Plant-based filtration is an effective and natural way to purify water while bushcrafting. Utilizing plant materials helps filter out impurities from water.

You can use charcoal from a burned piece of wood. Crush the charcoal into finer particles and layer it with sand and small pebbles in a container with small holes for draining.

Cattail roots are another useful material. Clean and crush the roots, packing them tightly into the filter. These roots help remove sediments and some contaminants.

Moss can also be used for filtration. Place a thick layer of moss at the base of your filter system. It helps trap larger particles and organisms present in the water.

A multi-layered filter uses various plant materials. Combine charcoal, sand, pebbles, and moss in separate layers to enhance filtration effectiveness.

These methods are accessible and can be applied using materials commonly found in nature. Always remember to follow each filtration step carefully for the best results.

10) Distillation

Distillation is one of the most effective ways to purify water. It involves heating water to create steam, which is then collected and condensed back into liquid form. This process removes most impurities, including bacteria, viruses, and heavy metals.

To start, you'll need a heat source, a container for boiling water, a collecting apparatus, and a cooling mechanism. You can use basic materials like a pot, a lid, and a separate container to catch the distilled water.

Place the pot with water over the heat source and position the collecting apparatus to capture the steam. As the water boils, steam will rise, leaving impurities behind. The steam then cools and condenses back into pure water in the collecting container.

This method is particularly useful when you're uncertain about the contaminants in your water source. It's highly reliable, especially when other purification methods might fall short.

Remember to be patient, as distillation can be time-consuming. The setup needs to be steady, and you'll need to wait for all the steam to condense fully before collecting the purified water.

This technique provides a reliable source of safe drinking water, making it indispensable for bushcrafting.
