The Sweetwater purification system couples the ability to filter particulates from the water as well as bacteria and most common protozoa, such as crypto and giarda, with the ability to inactivate 99.99% of all viruses, all while leaving your water tasting great in the process. The MSR Sweetwater is an award winning water purification system (winner of a “best of the best” 2009 Editors’ Choice Award from Women’s Adventure Magazine for ease-of-use and offering “extra protection and peace of mind.”) that would make a great complement to your backpacking ensemble. Let’s delve into the features below.


The MSR Sweetwater offers comprehensive protection from waterborne microorganisms and sediment by:

  • removing 99.9% of common waterborne protozoan parasites, such as crypto and giardia

With an output of 1.25 Liters per minute and a 4:1 mechanical advantage dual-action pump, this filter can serve the needs of several backpackers at your base camp. The filter can easily be cleaned in the field as well.

SteriPen Sidewinder Water Purification System

[amazon_link id=”B0046RES06″ target=”_blank” container=”” container_class=”” ]SteriPEN SidewinderHand POWERED UV Water Purifier[/amazon_link]When it comes to purifying the water you drink while in the backcountry, there are many different options available to you on the market. SteriPen is leading the way in water purification technology, apparent by the different models available from SteriPen. The SteriPen Sidewinder is a fascinating and exciting water purification system. One of the drawbacks of the SteriPen concept is the reliance on AA or CR123 batteries. With the Sidewinder model, however, there are no batteries required for operation. Let’s look at how the SteriPen Sidewinder purifies your water, as well as features and specifications of the specific model.


The SteriPen Sidewinder utilizes a hand crank to generate the energy required to power the UV light bulb, which in turn kills waterborne bacteria, viruses, and protozoa, such as crypto and giardia. The water purification system includes a SteriPen pre-filter, to remove sediment and particulate materials from the water (so you aren’t drinking sand and dirt). Also included is a 1 Liter BPA free water bottle that mates with the rest of the apparatus. Basically, all you have to do is fill the water bottle up (can be any 1 Liter Nalgene style wide-mouthed bottle) with pre-filtered water, attach the bottle to the purifier, turn the whole thing upside down, and swirl the water while you crank the handle approximately 2 revolutions per second for 90 seconds, or until the LED flashes green.

SteriPen is truly one of the most innovative outdoor product companies out there today, as is evident by the products that they are putting on the market. While the 16.6 ounces weighs quite a bit more than the smaller SteriPen Traveler or Adventurer Opti, the reassurance that you won’t be without water if your batteries run out or die on you is worth the extra few ounces. It will basically last you forever (8,000 Liters of water is a lot of water), so you won’t have to worry about batteries or replacement filters. I never leave home without my SteriPen Sidewinder, whether I am going on a road trip or a 12 day backpacking trip in the Rockies. Every backpacker should have a SteriPen Sidewinder water purifier. It is as simple as that. Click the following link to get yours today.
