Does the steripen work against "beaver fever" (Giardiasis). Having had it one time I could pass (sorry for the pun) on it again. The Giardia cyst is fairly hard to kill so I am wondering if the pen works

Thanks

Have you looked at the hydro flask??? It is pretty good as far as keeping things hot or cold and from what I hear they have all kinds of things to go with it filters being one of them.

I've been using the Bota of Boulder water bottle purifier for about 7 years now. Lightweight and cheap and most of all, I havent had any problems! I do have a cloth thermal holder that enables me to attach it to my belt while wading. I have fresh cold water immediately, all the time.

Yes indeed. Kills bacteria, cysts, protozoa, AND viruses. That is, Steripen is a true purifier unlike all the other products mentioned here. While filters will take care of most bacteria and cysts, only a true purifier will kill viruses as well. Viruses are far too small to be filtered, so they need be killed, either chemically (iodine or chlorine) or by bursts of UV. Steripen is a UV purifier much like those found in both residential and municipal water treatment systems.

NOTE: In my experience, most of the filters mentioned here are effective at what they are designed to do, IF USED PROPERLY. I have participated in a number of exercises that have tested these—in the field and in lab settings—extensively.

On that note, then, do they recommend a pre-filter with the Steripen?

We have a UV sterilization system in my home and my workplace, and the people that service both of these systems stress that UV is only as good as the pre-filtration, since it's easy for viruses and bacteria to "hide" behind small solid particulates and avoid most of the UV radiation and survive to make it into your body. For this reason (and the fact that there's always some small amount of solid particulate in moving natural water), I've always been very skeptical of the steripen as a standalone purification measure.

They just say that in case their product fails so you can't sue them
