Filter Water with the Push of a Button

This post is by Bernie Carr,


Today we are looking at the Survivor Filter Electric ProX, the world’s first portable electric water filter.  Long time readers know I am always trying out outdoor gear that may help in an emergency. Even if nothing happens you can still use it for camping, hiking or backpacking.

I am not affiliated with the makers of Survivor Filter Electric ProX. I received a review sample but the opinions expressed in this review are mine alone.

What comes with it?

How does it work?

The Survivor Filter Electric ProX sends the water through three stages of filtration:

Stage 1: The 0.1 Micron Membrane Pre-Filter

This 0.1 Micron Ultra Filter is the first barrier that helps remove algae, Giardia, E. Coli, Protozoa, and Cryptosporidium. The Pre-Filter is can be cleaned by backwashing using with the included syringe up to 100, 000 Liters.

Stage 2: The Carbon Filter

The Carbon Filter is designed to reduce heavy metals, chemicals, pollutants and improve the taste of the water. The Carbon Filter element will last up to 2000 Liters and can be replaced easily.

Stage 3: The 0.01 Micron Ultra Filter

The last layer is the internal membrane which acts as a barrier to remove the remaining pathogens that make it through Stages 1 and 2 such as viruses.  Once the water has passed through the first three stages, it should remove of 99.999% of tested virus (Phi-X 174), bacteria, parasites and staph.
The Internal Membrane is designed to be backwashed with the included Syringe and re-used up to 100, 000 liters.

Two-part test

First, we followed instructions to prime the the Survivor Filter, which was to install the batteries, assemble the filter and filling the reservoir with water.  There are written instructions in the box, and their website also includes a video showing how to prime the filter.
Now we are ready to test the Survivor Filter Electric ProX . We put the through two testing scenarios.

Colored dye test

This is the test I do on all my water filters, and if the water filter does not pass the test, I don’t even move forward with the review.
First, we mixed red food coloring into tap water and mixed well.
Then we placed the pre-filter with hose into the colored water, and attached it to the water filter.  The outlet hose then drains into a clear container.
We turned it on and the water started flowing.
As you can see from the photo, the red water goes in, while the water flowing into the container is very clear.
Here is the filtered water up close.
The Survivor Filter Electric ProX passed the colored dye test, and now we will try it out while camping.

River test

We went to Zion National Park and filtered water from the Virgin River using the Survivor Filter Electric ProX.
We placed the Survivor Filter in the river water, and filled a water bottle with the purified water.  We drank the water and it tasted great. We suffered no ill effects from drinking river water purified by the Survivor Filter Electric ProX.
Purifying river water into an empty water bottle.
Water purified with Survivor Filter Electric ProX tasted great.
As you can see, I put the Survivor Filter Electric ProX through the paces and it passed both tests. It produced clear, clean water. It takes no effort at all to filter water, no pumping required.  The flow rate is also good: 500ml (17 ounces) per minute.  It took only a minute or so to fill up a standard size water bottle.
The only downside is there is no manual backup if you run out of batteries.  If you use the Survivor Filter Electric ProX filter non-stop, it will last for around 4.5 hours to 5 hours on two AA batteries. You will need to bring extra batteries depending on how long your camping or backpacking trip will be, or you can also use rechargeable batteries with a solar charger.
I think the Survivor Filter Electric ProX would be good to have for emergencies, or for backpacking or camping. It makes water filtration very easy, and the filtration system removes most impurities such as bacteria, viruses, Staph and parasites.

  1. I’m using tap water from the 30 gallon drums I filled in 2011. I’m happy to report that I’ve filtered with a Berkey about 15 gallons, used to drink, and make tea.
    The water wasn’t given any additives, just filled fro the tap. It’s fine.
    Great news about the ProX.
