lifestraw

This product would have been our pick if it wasn’t so pricey. It truly is amazing.

This product is a water purifier that is gravity-powered. Having no batteries, chemicals or moving parts, the product does not expire.

The LifeStraw Mission sieves out over 99% of bacteria, protozoa, and viruses. It can therefore be filled from nearby lakes, rivers, streams and ponds.

Its large capacity makes the Mission water purifier ideal for clean water provision to multiple people, in group activities, camping, hunting, and emergency and disaster survival prep kits.

When the reservoir is suspended from a tree or any sturdy support, gravity pulls the water to the filter’s ultra-filtration membrane. Clean water then leaves through 0.02 micron pores in the hollow fibers, trapping the microbes and other contaminants inside. These are then flushed out by backwashing.

The Compact water purifier comes in a BPA-free roll bag reservoir with a wide mouth for easy filling, and a convenient shoulder strap for carrying. For easy storage and portability, it has a drawstring stuff-sack. Four extra pre-filter screens makes on-site maintenance easy.

Survivor – 0.05 Micron Water Filter Straw  – Best for the Individual Long Haul

The Survivor Filter water filter can be attached to water bottles to carry water on the go.Because of the replaceable parts making up the filtration system, the Survivor – 0.05 Micron Water Filter Straw can last for ages. Let us therefore begin this review by looking at the 3-stage filtration system:

  • Stage 1- The cotton Pre-Filter: this sits in the water inlet of the survivor filter, and acts as the first sieve against large particles. The product comes with 5 extra Cotton Pre-Filters.
  • Stage 2 – The Ultra-Filter: this 0.05 micron ultra filter barrier sieves algae and most microbes. It can be used for up to 100,000 liters of water (264 gallons). This filter is easy to change.
  • Stage 3 – The Carbon Filter: this reduces chemicals, heavy metals and unpleasant taste and odors from the water. It can be used for up to 1000 liters of water (26,417 gallons). The filter is removable.

And this is not just marketing hype. The microbe filtration claims have been tested and proved. The product comes with a hygienic flip-top and mouthpiece, from which one can drink directly – like a straw. All the same, it easily screws into most canteens and standard water bottles.

Because of its compact size and light weight – 7 inches, 3.5 ounces (100 g), the survival filter is easy to store and carry. This makes it ideal for all forms of outdoor activities and travel, in addition to the emergency response.

Now for the couple of downsides we found with this product: First, though it has capacity to filter large volumes of water and works perfectly for one person, it is a bit tricky to set up for use by a large group of people. However, each person in the group could get their own filter.
The Survivor Filter uses 3 levels of filtration: Cotton Pre-Filter, Ultra Filter and Carbon Filter

Secondly, the filter flow decreases with each liter filtered. You are forced to squeeze the bottle as you suck. Pre-filtering with a cloth could improve this.

Pros

  • Replaceable filters making it long lasting
  • Life time warranty
  • Easy to use
  • Light weight and compact
  • Can be used on most water bottles

Cons

  • Takes long to come up with enough water for simultaneous group use.
