Water Filtration Amazon SalesI’m going to try to wade through the huge market of water filtration systems, from diy water filtration experiments (types like gravity filters) to advanced systems (such as, desalinator systems for salt-water treatments). The methods for ensuring clean drinking water while camping/hiking of living off-the-grid are improving and keep getting lighter and easier.

Factors to Consider Before Buying A Water Filtration System

Water filtration systems can be very confusing for the novice buyer, there are so many different varieties and things to consider. The basic factors for a water filtration system are based on simplistic factors such as size, ease of carry, weight, price and how long it takes to treat the water are easy enough, but when you start adding in other advanced questions like filter type, how long the system lasts, replacement parts availability and cost, effective rates, and which types of organisms they remove you will need to start researching your needs, environment and budget.

It is recommended that you treat all water you drink while hiking or camping, most risks are not visible and it’s always better to be safe then sorry. The most common types of water-born pathogens, bacteria and viruses include protozoa, e. coli, dysentery, hepatitis and rotovirus, which can all cause some pretty serious side effects on our bodies, mostly centered around the stomach and intestines.

Threats Types Symptoms Methods of Treatment
Protozoa Cryptosporidium parvum, Giardia lamblia. Profuse, often watery diarrhea, vomiting, gas and intestinal discomfort. Most infections last 1 to 6 weeks; rare chronic cases can last up to a year. People with weakened immune systems need to be extra vigilant against contracting cryptosporidiosis. Boiling, mechanical filtration/purification; UV light. Chemicals and halogens are effective against Giardia, but not alwaysCryptosporidium.
Bacteria Escherichia coli (E. coli), Salmonella, Campylobacter jejuni, Yersinia entercolitica, Leptospira interrogans and many others. Diarrhea and potentially prolonged intestinal discomfort. A more serious bacteria-caused disorder, cholera, is rare in the United States but fairly common in some countries. It is usually associated with dehydration. It can result in death if not quickly treated. Boiling, mechanical filtration/purification; UV light; chemicals/halogens.
Viruses Hepatitis A, rotavirus, enterovirus, norovirus. Diarrhea, intestinal discomfort. Potentially a variety of other ailments. Boiling, purification; UV light; chemicals/halogens (though contact time, ranging from 5 minutes to 4 hours, is required).

What To Use To Purify Your Water

To purify your water you will want to use filter, chemical treatments or purifiers, or a combination of these items. Filter will eliminate certain bacteria and make your water taste better, but it provides no protection against viruses (such as rotovirus). Chemical treatments (water filtration tabs) can eliminate both viruses and bacteria, but takes a bit longer than filters and sometimes can make your water taste weird. UV Purifiers are effective against all bacteria, viruses and pathogens. These do not remove these things, instead they neutralize them, but they can be used with filters to remove some of these items too. Below is a table indicting what types of treatments work for which types of threats.

Method Protozoa Bacteria Viruses Process
Boiling Water is boiled for at least 1 minute.
Filter __ Water is strained through an internal element by pumping, gravity or sip/squeeze bottle.
Purifer Same as a filter but may include a chemical component.
Ultraviolet light Water is exposed to UV light; takes about 90 seconds per 32 fl. oz.
Chlorine dioxide Tablets are dissolved in water; requires 15 minute wait time.
Iodine √* Tablets, crystals or tincture are dissolved in water; requires 15 minute wait time. (Important: not for pregnant women or people with a thyroid condition).
