SteriPEN Adventurer Opti Handheld UV Water Purifier
The SteriPEN Adventurer Opti Handheld UV Water Purifier harnesses the power of ultraviolet light to make water safe to drink. This same technology is used by leading bottled water manufacturers as well as major cities in the US, Europe, and Asia to purify water.
The SteriPEN Adventurer Opti utilizes an optical eye to sense the water and project UV light to destroy 99.9% of bacteria, protozoa and viruses quickly and effectively. UV light does not alter the taste, pH, or other properties of the water, and works without the introduction of chemicals to the water. The handheld system is easy to use does not require pumping or time consuming filtration. The patent-pending technology ensures safe use and provides purification in even the coldest of waters.
The optical sensor also doubles a great backup light when camping or taking a night-time walk to refill your water bottle. The Flashlight mode is activated by pressing and holding the single button down for three seconds. The clear lamp cover focuses the LED light.

Pros: Lightweight, durable, effective, no bad taste!
Cons: It will be a little pricey to replace the batteries.
I used it in two Nalgene water bottles (one tinted charcoal grey and the other chartreuse yellow) and had no issues not seeing the UV light turn on - even at high noon. It'd take a minute or less to clean the water, dry the SteriPEN, and put it back into my bag where it takes hardly any space. Also, no hassles with pumps and tubes like my friend's filters.
My only gripe, which isn't much b/c its not that big of a deal, but I wish it would buzz or vibrate when it was done. I usually would scoop up the water at the base of my campsite and bring the water up to camp and talk with my friends while using the SteriPEN. I'd find myself a few times looking down after a bit and the light already had turned off - I'd get too carried away in conversation. It gives you a small blinking green light that lasts for about 20 seconds that'll tell you if the water is good to drink after it's finished purifying, but if you're talking to your friends or caught up in a sunrise or sunset or something worth seeing when out in the wilderness, it'd be nice for the system to vibrate to your hand to tell you it purified the water instead of being glued to watching the device the whole time.

I'm notoriously sloppy with water purification, drinking tap water in Mexico, ice cubes in Myanmar and river water in Colombia. In preparation for an expedition to cross Madagascar, where water sources would be unknown, I decided it was time to consider my health. My last big gear-buying spree was in 2005 - it's pretty amazing the advancements since. For any hardcore trip where you risk destroying water tablets, using up iodine on other activities or serious dehydration...get a SteriPEN.
Key moments I was particularly thankful for SteriPEN:
1) When porters topped off a group pot of water we'd boiled the night before, which we realized as we went to tank up for the day. Wait 30 minutes for purification tablets, or, re-purify starter bottles with two wands for immediate consumption? Easy.
2) When I ran out of water and found a river an entire village used to wash dishes, laundry and bathe. I ran through the purification process twice, just for fun, drinking within five minutes.
Since returning from this trip, I've undergone multiple blood tests- the only bacteria strain found was contracted pre-SteriPEN. Having this, I am much more likely to drink wisely on future trips.
The weight was nominal and, while you certainly want to use the included case, it's sturdy enough. I had it in the outer pocket of my pack much of the trip. I used it in multiple 40oz Kleen Kanteen metal containers, which the math was a little tricky on, but I just over-purified when in doubt. Also "works" on Camelbak sacks. I do agree with various other reviews noting it's a little awkward to ensure the wand is submerged while you're stirring (otherwise it shuts off), but it's not a big deal. The signal light is easy enough to keep an eye on, but it would be nice if placed at the end of the handle. A lot of folks warn of contamination around the lip or mouthpiece of your container. Slosh it around while you're purifying or rinse your mouthpiece off with a purified bottle. At the end of the day, my bottles were being dragged through rivers and muck so there are really only so many preventative measures one can take.
Like any tool a life might depend upon, I tested it before departing to at least verify the light remained on through a full cycle, etc. I would encourage anyone to do the same.
October 2016: I still recommend SteriPEN as your primary method of water purification. Also great for extended trips or living abroad.

Les bouteilles d'eau c'est trop contraignant et cher : les porter par 6 et le bisphénol m'ont conduit à trouver une solution me permettant de consommer l'eau du robinet.
Bien qu'en France la réglementation serait stricte, je préfère prendre les devants car je n'ai pas non plus confiance en la "qualité" de l'eau du robinet (résidus malgré leurs contrôles et filtrage en tout genre).
A présent je suis ravie de pouvoir filter l'eau du robinet. Je la met dans des bouteilles en verre comme à l'ancienne et puis au frigo !
Et hop : je bois de l'eau qui a le goût de l'eau des montagnes ou de l'eau de source. La qualité gustative est au RDV.
C'est un investissement qui paye à long terme tant au niveau de la qualité de l'eau que de la santé.
J'ai tout de même testé avec mon appareil, mais y'a pas trop de différence en ppm, peut être n'enlèverait-t-il que le mauvais ?
Eau du robinet sur Nice : 176 ppm
Filtrée : 136 ppm.
@ vous de juger !
I used it everyday for almost all of my water and I changed the batteries once. A great little thing if mineral water is hard to come by, its helped me out many a time when I have needed just a little water to brush my teeth, but cant be bothered to go out and find a shop!
Alternatives to this (things that kill viruses as well bacteria) are not terribly convincing, this is completely chemical free, and my tongue and general well being appreciate that.
I used it after filtering the water beforehand with a homemade gravity filter, as the water must be fairly clear to remain effective.
The only thing I would like to see improved is the strength of the led light which indicates the UV bulb is on; It can be a little difficult to see in direct sunlight, it is possible though, you may need to use your body to create a shadow. So not a massive issue!
Petit détail: il n'est pas possible de stériliser son eau directement dans sa bouteille en plastique (le goulot est trop étroit pour laisser passer le steri pen). J'ai dû pour ma part utiliser un gobelet transparent en plastique et ensuite transvaser l'eau dans ma bouteille.
Cela dit, la gêne est minimale.
