A compact and reliable water filter that purifies about a liter of water per minute. Made by Katadyn - this here is Swiss quality.
A plastic shell with active charcoal innards through which you pump the water and it comes out clean. Filters by 0,2 micron, which means 99,999 % of bacteria and protozoa won't get through, but to kill viruses you should use purification tablets. Also neutralizes any nasty flavors to some extent. You put the other tube into the water source and the other in your bottle or cup or whatever, then you pump it through the filter. Use the pre-filter to sort out larger debris in murky water. Very simple. Works with many hydration bladders too, for example, CamelBak and Source.
The following table shows the most common pathogens that make drinking water risky. The order is from largest to smallest: filters are rarely able to remove viruses from water, so it's recommended to use purification tablets after filtering for the best effect.
Family | Known examples | Size range |
---|---|---|
Protozoans | Amoeobiasis (Entamoeba histolytica) Giardia Lamblia (Giardia intestinalis) Cryptosporidium (Cryptosporidiumparvum) | 1 –15 µm |
Bacteria | E-coli (Escherichia coli) Salmonella (Salmonella typhimurium) Cholera (vibrio cholerae) | 0,2 – 5 µm |
Viruses | Hepatitis A Norwalk virus Rotavirus Poliovirus | ~0,02 – 0,2 µm |
