Making Sense Of The Different Filtration Style Systems

Many different styles of survival water filters can be a bit confusing.

Not knowing their exact function might not help you to choose the right one for your needs.

Below you will a quick and easy guide on each filter-style and their functions.

Here are the filter styles and the functions mentioned in this article:

Gravity-Fed/Gravity-Bag Style Filter

The gravity-fed bag filters are one of the easiest to use.

You hardly have to put in any effort with the gravity- fed bag because gravity does all the work for you.

You simply fill the bag up with water, hang it up somewhere high such as in a tree, and then gravity will do the rest.

The water will simply run down the tube and through the filter and then into the reservoir bag below.

And presto, you have clean and safe water without much effort.

The gravity-fed style is perfect for families of large groups as they can filter a large amount of water. 

Straw-Style Filter – Single Person Use

Straw-style filters are cool looking, larger than normal straws with portable hollow tubes that house the filter or filters.

You use it like you would a normal straw.

However, the great thing about these water filter straws is that you can suck water through them from any body of water.

Their filters are probably the simplest of filters however they are effective and do protect you from the bacteria and parasites within the water.

Because of its weight and size, they are perfect for single person use and traveling. 

Pump-Style Filter

Just as the name suggests, the pump-style filter makes use of a pump that is attached to a bag and a tube.

The tube is simply put into the body of water you want to filter.

You start pumping the handle, this, in turn, pumps water up through the tube, into the filter and then into the reservoir bag.

Providing you with safe clean water.

Easy to use, a great way to stock up on a good amount of water and ideal for a few people. 

Bottle-Style Filter

The water bottle-style is similar to the straw-style, the difference is that the straw which contains the filter/ filters are contained inside the bottle.

It’s easy to use, simply by filling the bottle with water from any source nearby and as you suck it through the straw it flows through the filter.

The water bottle-style is perfect for single-day outdoor activities.

It is lightweight making it perfect for clean water on the go.

Final Thoughts

There is no excuse to not be prepared and not being able to access clean water that is 99.99% safe.

The SteriPen Adventurer is perfect for the lone traveler or modern-day nomad.

Being affordable, durable, and versatile as well as portable.

And so for me, all of these survival water filters met the brief.

Grab the bottle-style filter to take along on your jogs or hikes.

Use the pump-style or gravity-fed bag style filter on your next family camping trip or your mountain expedition.

And be sure to have one of the straw-style filters on hand for any emergency at any time.

Ensuring you will have safe drinking water from any water source even a muddy puddle or a running stream. 

I hope you found this article interesting and highly informative.

I hope I did my part by helping you on your quest to find the right survival water filter to do the job that you require it for.
