Benefits of Using an Outdoor Water Purifier

Water is Life

If you find yourself in a hostile environment where water sources are heavily polluted, an outdoor water purifier could save your life. Know that humans can only survive up to two-three days of dehydration.

Provides Convenience

An outdoor water purifier helps ease up your load. It eliminates the need for bringing gallons of drinking water during camping.

Prevents Diseases

The hazards found in water are innumerable. Viruses, bacteria, and protozoa are most difficult to eliminate since these are organisms with a size in the range of microns. Each time you drink unsafe water, you risk yourself getting Typhoid, Cholera, and Hepatitis among others.

Disaster Preparedness

We probably won’t be expecting zombies to take over the world anytime soon, but it is a known reality that a natural disaster, a war, or any catastrophe that could bring an end-of-the-world scenario could possibly happen. Such an event will arrive unannounced and hence it would be best to prepare.

What to Look For

Microfiltration Efficiency

In choosing an outdoor water purifier, the most important factor to consider is its ability to filter bacteria, protozoa, and viruses that are responsible for a number of diseases. Opt for a purifier that can eliminate not just debris and other visible particles, but also pathogens that are as small as 0.2 microns in size.

Speed

A second can feel like a minute when you are thirsty. So, the next factor to consider is the purifier’s speed. Some brands can easily deliver 2.5 liters of purified water per minute, while some may ask you to wait a little bit more just for a liter. Regardless, the quality of the water used may affect the speed of treatment.

Capacity

Is it for personal or family use? Are you planning on storing drinking water for later use? These are questions you need to ask yourself so you can narrow down your choices. Outdoor water purifiers also vary in shapes and sizes. If you are thinking of bringing friends or family members during your trips, choose one that could deliver a continuous supply of drinking water. A purifier with a larger filtering medium provides a faster flow and hence more water.

Weight

It isn’t wise to carry a bulky water purifier if you are on the go. There are outdoor water purifiers that allow solo trekkers to travel as light as they can. Such types can be folded and kept in the backpack.

Ease of Use

An outdoor water purifier with a gravity filter would be the best option for convenience. Apart from its initial setup, all you have to do is wait for your water to be filtered. Most importantly, it allows you to utilize any type of water source, be it a stagnant pond or a flowing stream.


Final Thoughts

Don’t let the weariness of carrying a backpack full of bottled water hinder you from exploring the great outdoors. The next time you escape the bustling city, make sure you already have an outdoor water purifier with you!

The LifeStraw Mission is our favorite of the bunch because of its efficiency in eliminating pathogens and its versatility for being a gravity-type purifier. Like any product, it has its share of disadvantages but its pros surely outweigh its cons.

Nonetheless, we aim to help you choose the best outdoor water purifier and we made sure you can have a great choice for each activity be it family camps, trail running with friends, solo trekking, etc. Now that we’ve shown you the best outdoor water purifiers, you no longer have to do the guesswork!
