How To Pick The Right Water Filter

While searching for the best water filters for preppers, you may stumble upon various items. But it would be best if you considered every factor before hitting that buy button. Here’s a small guide to help you choose the right one.

Micron Rating

It indicates the filtering ability of the water filter—micron rating 0.1 means the water filter can remove contaminants of the size of 0.1 microns. The smaller the pore, the higher is the filtration.

  • 0.1 Microns means the filter can remove 99.9999% bacteria and 99.9% protozoa/cysts.
  • 0.02 rating means the filter can remove 99.99% of viruses, too, as they are 100 times smaller than bacteria.

Also, keep a note of micron rating, if it’s nominal or absolute.

Filter Flow Rate

Another vital metric to keep in mind is the flow rate. A powered system can produce filtered water at a much faster rate than a gravity-fed system. Depending upon the situation you need the water filter for, you can choose it.

Gravity-fed systems can pump out 1 to 4 gallons of water every hour. In contrast, powered systems can pump out the same quantity in a minute. But powered systems are more expensive than the former.

Size

Water filters for preppers come in all sizes to ensure they always consume clean water. If you need it for your bug-out bag or off-grid living, you would not want to bulk your load. The water filter should be easily portable. However, for everyday use or use among many people, you can go for a more oversized option.

Price

Again, it all falls upon your discretion. If you’re ready to shell out big bucks, you can bring in a water filter that does everything. For economical ones, there’s always a cheaper option available. Water filters for preppers come in different price options to choose from a diverse range.

Types of Water Filters

Tap water may not always be safe for direct consumption. Various bacteria, protozoa, viruses, sand, and other contaminants reside in the water and make them unsafe for drinking. Here we will look at different types of water filters for preppers for comprehensive emergency preparedness:

Carbon Filters

The United States Environment Protection Agency (US EPA) considers carbon filters an effective option to clear chemicals like pesticides, herbicides, and volatile organic compounds. They are of two types: solid block carbon filter (more effective) and granulated activated carbon (less effective).

Some benefits of using carbon filters are:

  • The porous filters remove contaminants efficiently. Keeps the salts and minerals of water intact.
  • They are easy to maintain and replace.
  • They do not burden your wallet.

Ultraviolet Filter

This is the more advanced form of filtration and can eliminate viruses, disease-causing pathogens, bacterias, molds, and other microorganisms. The UV treatment can remove the highly infectious hepatitis virus too.

Some of the benefits of UV Filtration System are:

  • Effective against disease-causing pathogens and hepatitis virus
  • Produces safe to consume water

Reverse Osmosis Filter

Save yourself from water-borne diseases with the reverse osmosis filtration system. The RO filter can remove bad taste and odor along with contaminants. Thus, it delivers completely safe and healthy drinking water to hydrate yourself.

Some benefits of Reverse Osmosis Filters are:

  • It prevents you from water-borne diseases
  • Eliminates terrible taste and odor

Conclusion

The best water filters for you is really a matter of preference. Do you live near the woods or a river? Are you smack in the middle of a city? Is your city prone to power outages or natural disasters?

Either way, we hope the information we provided has helped you to make an informed decision for you and your family.
