The Top 5 Most Reliable Water Purification Methods

When it comes to survival, having access to clean and safe drinking water is absolutely crucial. Our bodies can only survive for a few days without it, and consuming contaminated water can lead to serious health issues. That’s why it’s important to have reliable water purification methods in your survival kit. In this article, we will discuss the top 5 most reliable water purification methods that you can rely on in any survival situation.

1. Boiling

Boiling is one of the oldest and most effective methods of purifying water. It kills most types of pathogens, including bacteria, viruses, and parasites, by heating the water to a temperature that is high enough to destroy them. Boiling water for at least 1 minute (3 minutes at higher altitudes) will make it safe to drink.


  • Bring the water to a rolling boil, where large bubbles are rapidly breaking the surface.
  • Keep the water at a rolling boil for the required time.
  • Let the water cool down before drinking or storing.

2. Filtration

Filtration is another effective method for purifying water. It works by passing water through a filter medium that removes particles, bacteria, and protozoan cysts. There are different types of water filters available, including portable water filters, gravity filters, and pump filters. Some filters are even capable of removing viruses.


  • Choose a water filter with a filter size small enough to remove the specific pathogens found in your water source.
  • Read the instructions carefully to ensure proper usage and maintenance of the filter.
  • Consider carrying a spare filter in case the first one becomes clogged or damaged.

3. Chemical Disinfection

Chemical disinfection is a popular method used to purify water. It involves adding chemical disinfectants, such as chlorine dioxide tablets or iodine, to kill bacteria and viruses. This method is lightweight, portable, and effective for treating large quantities of water.


  • Follow the instructions on the chemical disinfection product for correct dosage and contact time.
  • Allow the chemical disinfectant to mix thoroughly with the water by stirring or shaking the container.
  • Use chemical disinfection as a backup method when other purification methods are not available.

4. Distillation

Distillation is a process that involves boiling water and then collecting the steam in a separate container, leaving behind impurities. It effectively removes contaminants such as heavy metals, salts, and most pathogens. Distillation requires heat to boil the water, making it less suitable for emergency situations.


  • Boil the water and collect the steam by using a condensation cone or a makeshift distillation setup.
  • Be cautious of the risk of burns caused by the hot steam during distillation.
  • Store the distilled water in clean containers to prevent recontamination.

5. UV Sterilization

UV sterilization uses ultraviolet light to kill bacteria, viruses, and other pathogens in water. It works by damaging their DNA, preventing them from reproducing. UV sterilizers are compact, lightweight, and easy to use. However, they require batteries or a power source to function.


  • Make sure the water is clear and free of particles before using a UV sterilizer.
  • Follow the manufacturer’s instructions for proper usage and exposure time.
  • Carry spare batteries or have a backup power source to ensure continuous operation.

Remember, in a survival situation, it’s important to have multiple water purification methods available in case one method is not feasible or fails. Consider combining different methods to increase the effectiveness and reliability of your water purification efforts.

My 2 Cents

Water is essential for our survival, and having access to clean and safe drinking water becomes even more critical in emergency situations. Whether you’re camping, hiking, or in a survival scenario, knowing how to purify water is a valuable skill.

While all the water purification methods mentioned in this article are effective, it’s important to assess your situation and choose the method that best suits your needs. For example, if you have access to a heat source, boiling is a reliable and straightforward option. On the other hand, if you’re on the move or have limited resources, portable water filters or chemical disinfection might be your best bet.

Whichever method you choose, always follow the instructions carefully, and be prepared with the necessary tools and supplies. Remember, in a survival situation, every drop counts, so make sure to conserve and purify water whenever possible.

Stay safe and stay prepared!
