7 Best Survival Water Filter Models On the Market Today

Spread the love

In survival mode, you rely on the available source of water. It could be a muddy puddle, algae-filled ponds, livestock tanks, rainwater harvesting from rooftops, or river runoffs.

Filtering is the fastest way to get drinkable water from wild water. This is why a water filter is a mandatory inclusion in your survival kit.

Water filters work in different ways to make the water drinkable to be useful during those emergencies. Today we shall explore how the different models work to determine the best survival water filters in these categories.

To protect you from entanglement in the trade jargon, we will start by clarifying the difference between two popular terms used hand in hand in water cleansing.

Water Filters

These are mechanical devices used to remove unwanted particles from the water using different kinds of media. They are rated according to the largest particle size that can pass through them while the water is being cleaned.

This size is measured in microns. A micron is one-millionth of a meter. The lower the micron rating, the purer the water output.

They can block bacterium, waterborne protozoa, and any other sediment that may be contained in the water from the source because they are smaller in size.

Water Purifiers

They also remove the same contaminants that are removed by filters in addition to eliminating minerals and rendering dangerous contaminants inactive. They kill even the smallest of viruses that are capable of passing through the filters.

Water purifiers employ different techniques to do this, like mechanical filtration, the introduction of chemicals, and UV light.

They are hollow tubes inside of which filter mediums are fitted. You use them like a straw to suck filtered water straight from the water source. The filter medium removes all harmful contaminants as the water passes through the tube.

They are simple to use, lightweight, portable and packable and are ideal for a single person.

Vestergaard’s LifeStraw Personal Water Filter has a -0.2-micron filter membrane pore size. This traps bacteria, microplastics, and parasites. It also traps all debris, reducing the water turbidity, and can filter up to 1000 gallons of water in its lifetime.

A hand pump water filter is a tube fitted with a water filtering medium inside, albeit larger than in-line water filters.

Due to their larger size, sucking is not applicable. They come fitted with hand pumps used to pull water through the filtering medium so that contaminants can be cleared.

They make up for their slightly bigger size and weight by pulling more water faster than in-line filters to serve a small party of people.

The Survivor Filter Pro portable water filter pump is one of the best hand pump water filters with a -0.01 micron protection enforced by three water filtration stages, including a carbon filter that will trap heavy metals and get rid of chemicals. It is good for up to 2000 liters of water.

A gravity filter is not the fastest when you are on the move and is more applicable if you are camping out or staying put for a while because it requires a bit of setup.

Instead of sucking or pumping the water through the filtering medium of a gravity filter, they are more passive and rely on gravity to pull the water through.

You fill water in a reservoir that will then be suspended above the water filter so that gravity can force the water through it and into another reservoir that is below the water filter.

Their best selling point is that they can hold a remarkably high water capacity at once, which can serve a large group without having to go for constant refills. You adjust the size of the gravity bag to fit the amount of water you intend to use.

Waterdrop Gravity Water Filter Straw is simple to use and versatile because the threads on the filter straw are standard, and you can use it with a water bottle when you don’t need to fill the gravity bag, like on a solo mission.

It also has provision for AA batteries and comes with two of its own high-energy alkaline batteries with which it can produce up to 96 gallons of purified water.

Dual Technology Filters

Katadyn Vario Water Filter, Dual Technology Microfilter for Personal or Small Group Camping, Backpacking or Emergency Preparedness
  • A simple turn engages a ceramic pre-filter for long life in dirty water or a pleated glass fiber filter in normal conditions
  • Produces up to two quarts per minute in the faster flow mode and one quart per minute in longer life mode
  • Uses a replaceable Katadyn carbon core and cleanable ceramic disc
  • Adapter base attaches directly to water bottles or an output hose can be used to fill hydration systems or larger containers
  • Glass fiber filter

These are water filters that allow you to switch from one filtering mode to another, depending on the water contamination.

This facilitates optimal usage of the water filter’s capabilities, ensuring it is not strained unnecessarily, thereby prolonging its lifespan.

The best illustration of this concept lies in the Katadyn Vario Multi Flow Water Microfilter. It has three filter levels: a pleated glass fiber primary filter, an adjustable silver-impregnated ceramic filter, and active charcoal or carbon granule for removing odors. The ceramic filter disc protects the micro primary filter, increasing its lifespan.

You use the fast flow rate method when the water is relatively clean with minimal debris. In this mode, you bypass the ceramic pre-filter. The pleated glass fiber and charcoal can handle this load effectively. It produces clean water faster.

If you select longer life mode, the pace will not be as fast, but the ceramic filter comes back in play, and the water has to pass through all three elements. This shields the primary filter from impact.

  • CLEAN WATER ON THE GO: Small Portable, and Powerful. Breeze Water Straw Filter is Just What You Need to Obtain Clean Water in Nearly any Emergency Circumstance, Or While Enjoying the Great Outdoors!

Water filters can remove impurities from water using physical barriers, chemical processes, or biological processes. Sometimes the quality of water is beyond purification by the primary water filtration method. Quality water filters institute a secondary means to complement it.

Activated charcoal is the most common medium. It is used to absorb toxic compounds from organic contamination and addresses issues such as taste and odor. Many of the Survival water filters we have reviewed here have an activated charcoal component.

While a water filter straw, this water filter straw for survival has a patented design allowing for multiple filtering options. It has a hollow ultra-filtration membrane and can easily transform contaminated water into safe and clean drinking water. It also allows for a hand pump option and has a water bottle attachment.

Classes of Water Impurities

Bacteria

These are mainly byproducts from animal and human fecal waste and come in many forms; E. coli, Salmonella, cholera, shigella, or coliform. The major harmful bacteria diseases transmitted via water are cholera, typhoid fever, and bacillary dysentery.

Protozoan Parasites

These are single-celled organisms that feed on organic matter and use the water to get into their host. They are larger and more advanced than bacteria.

Different protozoan parasites make you sick in different ways. The most common in water are Cryptosporidium, Giardia, and Entamoeba histolytica. They will live and feed off our intestines, causing diarrhea.

Cysts

They are resistant walls that form around the parasites, protecting them from harsh environments. The bacteria and protozoa can sit in dormant form, ready to activate inside your body.

Viruses

Some viruses found in water, such as the adenovirus, astrovirus, rotavirus, norovirus, Hepatitis A and E viruses, and others are classified among those with the ability to impact human health significantly by the World Health Organization (WHO).

Most are associated with gastroenteritis which causes diarrhea and other abdominal disorders. They can also lead to more severe illnesses such as Hepatitis A, SARS, polio, and HFMD (hand, foot, and mouth disease).

Heavy Metals

They are called heavy because they have a high atomic weight. Their density is approximately five times that of water. They are scattered all over the environment due to their many applications and often find their way into the water.

Over-ingestion can cause organ damage, and they have also been classified as carcinogens. Lead, mercury, arsenic, cadmium, and chromium have high toxicity levels and are given priority when purifying water.

Society Wastes

This category generalizes all contamination that arises courtesy of human activity and eventually finds its way into the water.

These include microplastics, pesticides, cleaning agents, industrial runoff, paint, and acid rain. The water is laced with chemicals, making it unfit for human consumption.

Sediments

These are solid pollutants collected by water runoff and deposited in nearby creeks, streams, and rivers. They are made loose by a combination of erosion, decomposition of plants and animals, and construction activities.

The contaminants include dirt, sand, silt, microplastics, plant and animal matter, and all kinds of debris. They degrade the quality of water for drinking.

Algae

Industrial waste and climate changes have led to the blooming of harmful algae in our water, which produce toxins that can cause illness or even death when ingested. These are the greenish brownish slime seen in waterbeds.

Water Cloudiness

The technical term for this is turbidity. It is usually an indicator of the presence of harmful bacteria, viruses, and other pathogens in the water.

Water in this state provides an environment for the growth of microbial that may be disease-causing. It also hinders disinfection.

How to Determine Which Survival Water Filter Is Suitable for Your Needs

When it comes to survival, you can never be too sure what your needs will be at the point of emergency. The safe move is to have a couple of options to choose from, but we need to factor in budgetary constraints as we make the selection.

Below are some of the considerations you should be pondering over when it comes to what emergency water filter you should have on hand.

Quality of the Source Water

If you know what contaminants you are removing from the water, you can concentrate on survival water filter models specifically designed to combat those impurities.

Try and keep up with the local water analysis reports from reliable sources like county health departments and the Environmental Protection Agency (EPA).

They usually include the concentration of contaminants, which should help in making your preparation relevant.

The closer you are to the water source, the less treatment the water will need because it hasn’t had a lot of exposure to contamination.

The further it flows downstream and the closer it comes to human activity, the more contaminated it becomes. You will need more than a basic filter to clean this water.

The Size of Your Party

A basic in-line water filter will suffice for your individual survival. You may be forced to consider other options for a group of people unless everyone has their own water filter.

This reduces efficiency as you will spend a lot of time getting water as opposed to serving everyone with the faster hand-pumped water filter.

Gravity-fed filters are also ideal for larger groups camping in one place as the setup will be faster, and they have a larger holding capacity.

Portability of the Survival Water Filter

The lighter you pack, the more agile you are and the further you can move before fatigue sets in. if you are alone, the small in-line water filter will suit your purposes.

In a group, you need to weigh the convenience of a water purifier against the speed with which you will purify the water and prioritize.

Think about how much weight it could be if you could only carry bottled water instead of a smaller and more convenient emergency water filter for safe drinking water.

The Budget

The ideal situation is to have survival water purification for every perceivable scenario. That may not be possible because you need more gear to complete the full survival kit while covering your everyday expenses.

Prioritize your requirements and make a checklist in that order. Then you can go for the portable water filter that checks the most boxes.

You can build your water filter collection over time using the same criteria but changing priorities to cover the gaps left by the previous filter.

Having at least two diverse filters in your backpack gives you access to more water options. You will have covered all your bases so you can adapt to the situation at hand.

At about 8.3 pounds per gallon, water is considerably hefty. Adult humans need about a gallon of water per day, so it is impractical to think you can carry all the water you need when required to be on the road for days. You should be prepared for fetching water on the go.

This does not take away from the sense of having at least 24 ounces of water in your survival pack at all times as a safety measure. This will be your initial water source before you can identify others.
