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.

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.
