Travelers Rule #1: Don’t drink the water!
It is one of the most common and most embarrassing travel-related illnesses. Between 30% to 70% of travelers are affected, depending on the destination and season.
Bad water can cause even more serious problems than a couple days of diarrhea. Certain amoebas and parasites can only be treated with very strong medication.
But what are you supposed to do? Bottled water is okay as long as it’s available. But what if there are no stores nearby? And buying water can get expensive.
Does SteriPen Actually Make Water Safe?
After writing about drinking water and how to stay safe, SteriPEN contacted us and asked us to test and review one of their UV sterilizing units for travelers.
The model they sent us to test was the SteriPEN Ultra (with USB charging).
We had two options to test the UV light:
- Use the pen, drink the water, and see if we get sick
- Test the results in a lab
While option #1 sounds tempting, we decided on option #2. Here’s what we did.
How We Tested the SteriPEN Ultra
To find out if it really worked, we took water samples from two unlikely places (both in Cuenca, Ecuador):
- a public washroom in a busy shopping center
- the Tomebamba River (one of the four rivers that run through the city)
We then tested them in a lab. Here’s what we found.
- The tap water passed the test without treatment. While it did have some bacteria, it was safe to drink. This is impressive, given that we took the sample from a public washroom. As you will see in the video below, I did let the water run for a few seconds first and we used a sterilized container.
- The river water, of course, was full of life – and dangerous to consume. In addition to a lot of rotting organic material we found bacteria, amoebas, amoeba eggs, and parasite eggs.
Here are photos of some of the wildlife from the river water:
Once we established that the river water was unsafe, we then we treated the same water with the SteriPEN Ultra and retested the water.
Did The SteriPEN Work? Our SteriPEN Review
Yes. All the life, including amoebas, parasites and bacteria were killed by the SteriPEN and it was safe to drink. It was even safer than the treated/filtered tap water in the same city because everything was dead – including the bacteria.
I should mention that I didn’t stir the unit properly in the test. I was supposed to keep it in motion during the test to ensure uniform purification – but I forgot. In spite of that, it still eliminated all of the living contaminants in the water. See the end of the post for more tips on proper use.
Here are two image of the same amoeba:
I was really impressed by this test. Seeing the same organism alive and then dead from the UV light convinced me. We are going to use the SteriPEN on all questionable water from now on.

SteriPEN Ultra Features
Here are some of the key features of the model we tested:
- Works in 48 seconds (500 ml) or 90 seconds (1 liter)
- Treats up to 8,000 liters (over 7 years of safe drinking water for one person)
- Destroys 99.9999% of bacteria, 99.99% of viruses, 99.9% of protozoa
- USB rechargeable from a computer, wall socket or solar panel
It is quite fool-proof: The Ultra model displays a smiley face when you have successfully treated the water and it won’t turn on unless it is properly submerged in the water.
9 Tips for Safely Using the SteriPEN
Here are a few things to keep in mind as you get started with the SteriPEN:
- The unit should be moved in a stirring motion during water treatment. This agitation helps ensure consistent purification.
- SteriPEN is meant for use in clear water. It can be used to treat turbid or cloudy water in an emergency. It is always best to physically filter the water to remove as much dirt and silt as possible. This material will affect the effectiveness of the UV light. SteriPEN recommends doubling the treatment time on cloudy water.
- The UV lamp emits both visible and UV light. If the lamp isn’t emitting visible light it needs to be repaired or replaced.
- The UV light will not treat water droplets on the mouth of the water bottle. Always be sure that the mouth of your bottle is clean and dry before drinking purified water.
- Because glass, plastic, ceramic and metal all absorb or reflect UV light, you are not at risk for UV exposure.
- Do not use in water above 120°F / 49°C
- A fully charged SteriPEN can treat approximately 50 liters of water. Always charge your unit before heading out.
- The OLED screen will indicate when the bulb is nearing it’s end – displaying when it has less than 100 treatments left.
- The unit has two water-sensing pins. They must be submerged in the water in order for the light to turn on.
3 More Reasons to Use SteriPEN
SteriPEN not only keeps you healthy. There are other key benefits.
- Save Money: Let’s do a little math. One SteriPEN will purify 8000 liters of water. That means you won’t buy 16,000 bottles of water. Even here in Ecuador where water is cheap ($0.30/500ml bottle) this would save you $4800 for the life of the purifier. Water can cost between $0.03 and $3.00 for a 500ml bottle. At less than $100, the SteriPEN makes good economic sense.
- Save Time: Water isn’t always available. Who wants to spend time your travel time looking for a bottle of water? Just take some tap water, treat it and enjoy your travels.
- Save the Environment: Beside the costs of buying water, there is also the environmental impact of thousands of bottles of water. By purifying 8,000 liters of water (the life of a SteriPEN) you are keeping 16,000 bottles out of the landfills.
