This video is actually quite funny.
What is the best wilderness water filter system?
First off there are about a dozen different options for purifying your drinking water. We will put them into a few categories to make things easy.
First we have tablets and drops. Where you basically add some chemicals to your water to kill any bacteria and bugs etc.
Unless you want pieces of (stuff) in your water while you are trying to drink it you will also need some sort of filter.
Not convenient at all in my opinion.
Probably my next least favorite would be The SteriPEN Classic ($70) uses ultraviolet light to neutralize bacteria and protozoa in your water, including giardia and cryptosporidium. The Classic takes four easy-to-resupply AA batteries which can purify up to 150 liters of water. Fast and easy to use, it purifies a half liter of water in 48 seconds or 1 liter in 90 seconds. However, a pre-filter must be used to remove any sediment because the SteriPEN is only effective in clear water. The SteriPEN Classic is also an excellent water treatment option for colder weather and even winter, when ice can damage a water filter and cold temperatures slow chemical reactions. Weighs 6.3 ounces w/ batteries.
Its expensive, needs a filter, uses batteries and is heavy...No thanks.
Next up is the Sawyer Point One Water Filter, 2 x 64 ounce and 1 x 16 ounce soft bottles, a plastic syringe for cleaning, hydration system adapters, and a straw. Like the Sawyer Mini, you can drink directly from the Sawyer Squeeze but most people squeeze untreated water through it from a soft bottle to a clean container. The filter uses a hollow-fiber membrane filter that removes 99.99999% of all bacteria, such as salmonella, cholera and E.coli and removes 99.9999% of all protozoa, such as giardia and Cryptosporidium. The filter itself weighs 3 ounces.
A pretty good system, a little pricey but quite easy to work with over all. Comes in at 3rd place.
My #1 and #2 choices are made by the same company LifeStraw.
First: The Lifestraw Flex ($35) is a screw-on style backcountry water filter that is compatible with a wide range of soda-sized water bottles and reservoirs. While it comes with its own 22 oz soft-bottle, you can also screw it onto standard-sized soda bottles, Platypus or Evernew reservoirs, integrate it into a hose-based hydration system, use it in a gravity filter configuration, or as a drinking straw. It’s 0.2 micron filter is EPA tested to remove 99.999999 % of bacteria and 99.999 % of parasites and includes an add-on activated carbon capsule which reduces chlorine, lead, and improves water taste. The filter has an expected lifetime of 2000 liters and weighs 3.5 oz dry.
Second place goes to the older leaner little brother: The LifeStraw water filter ($20) weighs just two ounces and is extremely portable, making it an excellent option for day hikers as well as backpackers. It removes 99.9999% of waterborne bacteria, including E. coli and salmonella and 99.9% waterborne protozoa, including giardia and cryptosporidium. While you can sip water through the LifeStraw directly from a stream or pond, most people scoop up water using a small bottle or cup. The LifeStraw can filter up to 1,000 liters. To clean the LifeStraw, blow air back through the filter to drain any residual liquid after use, effectively backflushing it. Weight: 2 ounces.
I especially like this one for its size weight and ease of use. Plus its wicked cheap.
