Your Essential Guide to Survival Water Filters
When the unexpected happens, clean water becomes your top priority. A reliable survival water filter can mean the difference between staying healthy and facing serious illness. This guide will help you choose the best filter for your emergency kit.
Key Features to Look For
When you’re choosing a survival water filter, keep these important features in mind:
- Filtration Level: This is the most crucial part. You want a filter that removes bacteria, protozoa, and ideally viruses. Look for filters that meet or exceed NSF/ANSI standards for water purification.
- Flow Rate: How quickly does the water come through? A good flow rate means you won’t be waiting long for a drink. Some filters can be slow, especially when they start to clog.
- Durability: Your filter needs to withstand rough handling. Look for sturdy materials and a design that can take a beating.
- Ease of Use: In a stressful situation, you need a filter that’s simple to operate. Can you easily pump it, suck through it, or set it up?
- Weight and Portability: If you need to move, you’ll want a filter that’s light and doesn’t take up much space in your backpack.
- Lifespan: How much water can the filter clean before it needs to be replaced or cleaned? A longer lifespan means more value and less worry about running out of clean water.
- Backflushing Capability: Some filters can be cleaned by pushing clean water back through them. This helps them last longer and maintain a good flow rate.
Important Materials
The materials used in a survival water filter affect its performance and durability.
- Filter Media: This is the heart of the filter. Common materials include hollow-fiber membranes, ceramic, and activated carbon. Hollow-fiber membranes are excellent at trapping small particles. Ceramic filters are durable and can be cleaned, but they can be slower. Activated carbon helps improve taste and remove chemicals.
- Casing: The outer shell should be made of strong, food-grade plastic or metal. This protects the delicate filter media inside and ensures the water stays clean.
Factors That Improve or Reduce Quality
Certain things make a survival water filter better or worse.
- Improvements:
- Multiple Stages of Filtration: Filters with several stages (like pre-filters, main filters, and sometimes carbon filters) remove a wider range of contaminants.
- High Pore Size Rating: A smaller pore size (measured in microns) means it can trap smaller particles, including harmful bacteria and protozoa. A rating of 0.1 to 0.2 microns is generally considered very good for bacteria.
- Ease of Cleaning: Filters that can be easily backflushed or have replaceable parts will last longer and perform better over time.
- Reductions:
- Clogging: If the filter gets clogged with sediment, the flow rate will decrease, and it will become harder to use.
- Freezing: Water filters can be damaged if water inside them freezes and expands. Always protect your filter from freezing temperatures.
- Chemical Contamination: Most basic survival filters are not designed to remove dissolved chemicals or heavy metals. For those, you might need a more advanced system or chemical treatment.
User Experience and Use Cases
How you use your filter and what you expect from it matters.
- User Experience: Many users find straw-style filters very convenient for drinking directly from a water source. Pump filters are good for filling up bottles or containers. Gravity filters are great for filtering larger amounts of water with less effort.
- Use Cases:
- Hiking and Camping: Essential for staying hydrated on the trail.
- Emergency Preparedness: A must-have for your home emergency kit in case municipal water is compromised.
- Travel: Useful in areas where water quality is questionable.
- Bug-Out Scenarios: When you need to relocate and rely on natural water sources.
Frequently Asked Questions (FAQ)
Q: What is the most important thing to look for in a survival water filter?
A: The most important thing is its filtration level. It needs to remove harmful bacteria and protozoa.
Q: Can survival water filters remove viruses?
A: Some advanced filters can remove viruses, but many basic survival filters cannot. You might need a filter with a very small pore size or use a chemical treatment along with it.
Q: How long do survival water filters last?
A: Filter lifespan varies greatly. Some can filter thousands of gallons, while others might only filter a few hundred. Always check the product’s specifications.
Q: What’s the difference between a straw filter and a pump filter?
A: A straw filter lets you drink directly from a water source. A pump filter uses a handle to push water through the filter into a container.
Q: Can I use my survival filter with saltwater?
A: No, most survival water filters are not designed to remove salt. You would need a desalination system for saltwater.
Q: How do I maintain my survival water filter?
A: Follow the manufacturer’s instructions. This often involves backflushing the filter regularly and storing it properly to prevent damage.
Q: What happens if my filter freezes?
A: Freezing can damage the filter media, making it less effective or unusable. Try to keep it from freezing.
Q: Are there any chemicals in survival water filters?
A: The filter media itself is usually safe. However, some filters include activated carbon, which can improve taste by removing chlorine and other chemicals.
Q: How do I know if my filter is still working?
A: If the flow rate significantly decreases, or if the water still tastes or smells bad after filtering, it might be time to clean or replace the filter.
Q: Should I carry a backup water purification method?
A: Yes, it’s always wise to have a backup, such as purification tablets or a small boiling pot, in case your primary filter fails.
