SteriPen

<p>Use shortwave ultraviolet light to disinfect your water. When you immerse the lamp in the water it disrupts the DNA of bacteria, viruses and protozoa, rendering them harmless. SteriPen is most effective with clear water. It does reduce microbial contamination in mildly turbid water, but you should consider pre-filtering any time you expect to encounter muddy or silty water sources.</p><ul><li>Treatment of .5L takes approximately 45 seconds and 1.0L takes approximately 90 seconds</li><li>Lamp life is approximately 8,000 treatments</li><li>Requires 4 AA batteries (not included)</li><li>Manufacturer’s tests with lithium batteries treated approximately 150L.

SteriPen Classic 3 Water Purifier

Water can be treated using various types of filters, chemicals or non-chemical purification methods, or a combination. Filters on their own will not remove viruses as they are too small.

The life of the filter cartridge is based on the quantity of water you can treat before the cartridge is no longer effective. This does not apply to battery operated or chemical filter systems.

Most viruses are in the 0.1 micron size range, but they can be as small as 0.002 microns.

Particulate consists of very small bits and pieces such as dirt or bugs.

Protozoa are larger than one micron and include cryptosporidium and giardia. 

Bacteria can cause illnesses such as diarrhea and dysentery and are about 1.0 micron in size, although some can be as small as 0.2 microns.
