Quick Answer
When venturing into the wild, ensure access to clean water with these five essential items: a water filter, water purification tablets, a portable UV water purifier, a solar still, and a water bottle with a built-in filter.
Essential Water Filtration Tools
When selecting a water filter or purification method, consider the contaminants you’re likely to encounter in the wild. For example, a water filter with 0.2-micron pores can remove bacteria, parasites, and sediment, while a UV purifier can kill viruses and bacteria with a dose of 30,000 to 40,000 millijoules per liter. Look for products that have been certified by organizations such as NSF International or the World Health Organization.
Water Purification Methods
In addition to filters and UV purifiers, consider using water purification tablets or boiling water to make it safe for consumption. Water purification tablets typically require 30 minutes to 1 hour to be effective and can remove bacteria, viruses, and parasites. To boil water, bring it to a rolling boil for 1-3 minutes at an elevation of up to 6,500 feet. If you’re unable to boil water, use a solar still to purify it. A solar still can evaporate water and then collect the condensed water, which is free from many contaminants.
Practical Water Collection and Storage
Once you have access to clean water, it’s essential to store it properly to prevent contamination. Use a water bottle with a built-in filter to store and transport clean water. Consider using a water bottle with a capacity of at least 1 liter to ensure you have enough water for drinking and other uses. When collecting water from a natural source, use a scoop or container to avoid contaminating the water with your hands or other objects.
