There are two modern ways to kill all pathogens, including viruses. The SteriPens are one. The other is the Aquamira Water Treatment Drops. The Aquamira drops work by reacting to produce an oxygenated chemical that does the work. The reacting and treatment can easily be done in the backcountry. The whole process takes at least 20 minutes but you can keep hiking for most of that. The SteriPens work by producing sterilizing UV light and take only a few minutes. The Classic 3 can use any type of AA battery, including rechargeables or, in an emergency, readily available alkalines. You get about 150 liters from a set of lithiums. The SteriPen weighs 141 g with batteries. The 1 oz Aquamira kit weighs about 75 g and treats 115 liters; you can adjust the mix for different volumes, such as 20 oz instead of a liter.
Another option would be to use Aquatab tablets. These create the same oxygenated chemical as Aquamira drops and also take about a half hour to work. They cost about ten cents per quart of treated water whereas Aquamira costs about a penny.
The SteriPen pre-filter is a nice addition, even though it's relatively heavy. It connects to the nifty Nalgene On-The-Fly 22-oz water bottle, but imperfectly. The 40-micron filter won't remove cloudiness and certainly not pathogens. You could also use a coffee filter or even a bandanna. If you don't need to filter out pine needles and chipmunks you can jam the SteriPen directly into the filled bottle's drinking tube. If you use repurposed 590 ml energy drink bottles to hold your water, as many thru-hikers do, you can drill a 7/8” hole in a spare cap and wedge the SteriPen into it during treatment—a perfect solution, except you'll have to decide whether to use the half liter or full liter treatment options depending on clarity and source of the water.
You have to be aware that no system works on water that's in the threads of containers, and both are less effective at treating the bacterial biofilms that form on tiny particles in cloudy water. You have to take care not contaminate your purified drinking water with even a drop of untreated water in your apparatus, as some pathogens need only a few organisms to cause an infection. Be sure to dry out those threads, and don't brush your teeth with untreated water. Aquamira treated water kills pathogens that it comes into contact with during the time it is working, so you can use that to your advantage, but SteriPen treated water is always inert.
One worry about the SteriPens used to be the life of the UV discharge tube. SteriPen has addressed that with their Premium Lamp Life Pledge. When the number of treatments with your registered unit approaches 8,000 SteriPen will send you a brand new unit. That's one reason I have decided to use a SteriPen when appropriate: not because I think that I will ever use it up, but because I admire a company that stands behind its products.
You should understand some things about acquired intestinal distress. Water-born illness doesn't come on immediately; most infections take about a week or so to manifest. If illness comes on more quickly, the most likely cause is food poisoning. If illness appears on an outing, you probably were infected beforehand. The most common mode of acquiring intestinal distress is, ahem, fecal-oral transmission. Avoiding that transmission process requires diligent hand washing when preparing food in the back country, something that is seldom assiduously practiced. I suspect that nearly all clear back country water is OK to drink without treatment except that downstream from persistent human habitation, but even if you become infected, you'll be home before it hits you.
The pre-filter is a great idea, and I am glad it came with this. The only downside is tha fact it will only fit a nalgene size water bottle, and doesn't have adapters to fit slightly different bottle sizes. (I have a stanley canteen with a much smaller screw top.) But if you do have the nalgee sixed wider mouth, and come across a gunk filled pool of water, this pre filter will keep you from getting dead leaves and stick particles into your water, before you sterilize it. I think that's a great idea, and a plus to include it in this package.
What are you waiting for (like a lot of other people say)! Just get one!
Over the years, I've had one issue and one lost part. In both cases, customer service went above and beyond to get me the parts I needed. They stand by their product...and they're nice about it.

All I can say it is I am still alive and well after using it for a week to purify water from rivers and lakes in the alps.
It eats through batteries so if you're going for an extended trek I would advise getting some rechargeable batteries and a method of charging them.
This does not distort the taste anymore then the water already is from a lake/river. This doesn't make crystal clear water as it doesn't add bleach or other chemicals to the mixture. This is a good thing if people can make the mentle hurdler over drinking real water (lake or river)
Just just came from Pakashkag Lake where the water was hued green. We are perfectly fine and still drinking that water on the way home.
We carry a life straw as a battery-less back up but you cannot purify water you might wish to use in food or for tea with the straw!
EDIT: While we still love the steripen, we are dropping 1 star from it. This requires very high quality batteries and is does not suggest this anywhere easily. Upon watching you tube videos after running into trouble, this product is only realiable with high end batteries. We were using regular-nothing-fancy AA's and when they were cold (eg left in a tent over night while camping) this would fail to start up. We needed to take out the batteries and warm them up, and warm the unit up to get about a 50 percent working rate. Very annoying when you rely on this for you water.
I suggest to the company to increase the price and include 4 highly compatible batteries with a suggested list of recommended battery brands to purchase for the reasons I am listing.
It worked great! Somewhat time consuming, but I would sterilize a few litres at a time and keep the extra bottles in the fridge in our rental. It's somewhat heavy, mostly due to the batteries. Plus I made sure to pack it securely in my suitcase, well-cushioned in clothing so it wouldn't break since the bulb is housed inside a glass "tubule"
The UV sterilizer is extremely easy to use and works as described. I think it is a good purchase that I will use for a long time.
Once I worked up the courage to try it and make sure to follow the instructions carefully it worked! (Meaning I drank water from the wild without getting sick).
I don't know if the water I drank might have been safe without the UV treatment, but I believe in the science enough to trust it now.
I wouldnt recommend this product, and i dont and wont rely on this product with my life. I do a lot of back packing and i need a reliable heavy duty product that will stand the test of time. This product is not it. This can be a great product to have in your car for emergency or for short day hikes here and there where the worst case scenario is a little bit of dehydration for 12 hours. I would instead recommend some pristine tabs and the sawyer mini for filtration.
My intentions are to use it with a nasal rinse. I use it on my already clean water but would also use it for drinking water while traveling.
👍 for me
