Our Selection of the 5 Best Water Purification Pens:

If you have a need for one, you can check out our list of the best water purification pens, and maybe there will be something there that will catch your eye.

1. LifeStraw Personal Water Filter

LifeStraw Personal Water Filter

Our first item is LifeStraw water filter pen/straw. Easy to use and highly reliable, this pen has been a favorite among adventurers of all kinds. The pen is simple to use – just pop the cap, put it in the water and start drinking – and that’s it. The hollow fiber membrane filters out most 99.9% bacteria, protozoa and viruses, making sure that the water you’re drinking it not in the least contaminated. The pen has a maximum capacity of 1000 liters.

The splendid pen is also quite affordable, and you can find it on amazon for under 20$.

2. SteriPen Ultra UV Water Purifier

SteriPen Ultra UV Water Purifier

Not all purifiers need filters, and SteriPen (you’ll get to see this name often) uses UV light to ensure that your water is clean and safe to drink. The purifier is very powerful, and it removes 99.9% bacteria, viruses and protozoa by killing them and disabling their reproduction. In fact, the device is just as efficient as the VitalityStraw water filter straw.

However, SteriPen has a much larger capacity, and it can go for 300 discharge cycles on a single charge, which is close to 15,000 liters purified. The battery is recharged via simple USB cable.

3. SteriPen Traveler Mini Water Purifier

SteriPen Traveler Mini Water Purifier

Like we said, you’ll see SteriPen a lot, and their Traveler Mini Water Purifier is a smaller, but equally powerful, iteration of the Ultra UV water purifier. This tiny pen is superbly effective against all above-mentioned contaminants, delivering the same performance as both the Ultra UV and VitalityStraw. Not only that, but the UV does not leave an aftertaste, nor does it alter pH levels.

The only difference between this pen and the Ultra is that this pen is rated to 3000 liters, as opposed to Ultra’s 15,000.

4. Meco Water Filter Straw

Meco Water Filter StrawOur penultimate product is another straw, this time from Meco. Just like VitalityStraw, this is a highly effective and simple device. It uses a hollow fiber membrane filter that retains up to 99.9% contaminants. Of course, the device needs cleaning once in a while, and you can do it by simply backflushing. The straw is even more reliable than UV devices, as it requires no batteries. However, it has a lower capacity rating, being rated to 2000 liters.

The pen is also inexpensive, and can be purchased off Amazon for 20$.

5. SteriPen Adventurer Opti UV Water Purifier

SteriPen Adventurer Opti UV Water PurifierOur last item comes again from SteriPen. This marvelous device uses UV light to destroy all contaminants, making any puddle of water as clean as a mountain spring. Not only that, but the UV light does not leave an aftertaste, nor does it change the pH value or other chemical traits of the water. The device is rated to purifying up to 8000 liters of water before requiring you to recharge it. It also doubles up as a flashlight.

The device costs about the same as other SteirPen products, which is about 90 bucks.
