Make a Water Filter
Connor O’Malley contributed to this report. Making a water filter is an essential survival skill that should be learned. A thousand years ago, humans were free to roam the landscape of North America, drinking whatever water they liked. We regret to inform you that this is not the case anymore. The majority of the toxins and pathogens found in our water, such as giardia, are capable of causing severe disease – illness that might easily prove lethal in an emergency survival situation. Except for when you are certain that the water you are drinking is safe, you should cleanse it using whatever procedures are necessary.
It is possible to build a primitive water filter out of natural materials to filter out sediments and aromas if your water includes a high concentration of sediments and/or strong scents.
A Survival Water Filter
Connor O’Malley contributed to this article. Making a water filter is a critical survival skill that should be learned early on. It was a thousand years ago when humans were free to roam the landscape of North America, drinking any water they wanted. We regret to inform you that this is not the situation now. The majority of the toxins and pathogens found in our water, such as giardia, are capable of causing severe disease – illness that might easily prove lethal in an emergency survival scenario.
The use of modern water filters with micron-sized holes is particularly successful in filtering out giardia, and if you don’t have access to one, boiling water is the next best alternative if you don’t have one available.
Step 1: Gather Your Materials
Written by Connor O’Malley Making a water filter is an important survival skill to learn. A thousand years ago, humans were free to roam over North America, drinking whatever water they liked. Unfortunately, this is no longer the case. The majority of the toxins and pathogens found in our water, such as giardia, have the potential to cause severe sickness – illness that might quickly prove lethal in an emergency survival situation. If you are not certain that the water you are drinking is safe, you should purify it using whatever procedures are necessary.
If your water includes a high concentration of sediments and/or strong scents, you can build a primitive water filter out of natural materials to filter out the sediments and odors.
Step 2: Build the Filter
This filter is actually rather basic and straightforward to construct. The most difficult phase is heating the water that you have purified. The first step is to wrap the bark into a cone and then use your knife to punch a hole in the overlapping portions of the cone. (See Illustration 1) To finish it off, thread the leaf or branch that you selected earlier through the hole and tie the ends together with a square knot. If you do not know how to tie a square knot, you may go to my earlier instructable for instructions on how to tie one.
Bring all of the corners of the fabric together so that the charcoal is at the bottom of the cloth (see figure 4).
Step 3: Find Water
I’ll demonstrate five effective methods for finding water in the wilderness:
- The use of a solar still, plant perspiration, vine cutting, and the use of standing water are all discussed.
Lakes and ponds are a good example (image 1). Standing water is particularly easy to extract water from since it is so concentrated. All that is required is to scoop up the water, pass it through a filter, and bring it to a boil. Make an effort to use larger sources of standing water because the sediment to water ratio will be lower this way. Always scoop the water out of the water by scooping it from the surface of the water. 2. Rivers, creeks, and streams are examples of watercourses (image 2).
The main issue with running water is that it can be in a very little stream, making it difficult to fill a container with it at times.

Step 4: Boil the Water for Purification
Boiling water in the wilderness is a difficult and laborious chore that may be exceedingly aggravating. I’ll demonstrate one method of boiling water using only natural ingredients, and I’ll provide you with options for alternative methods. The method I’ll demonstrate involves boiling water in a hole in the ground. You will need to be in an area where clay is present beneath the surface of the soil. We will use the clay to line the hole in the ground, ensuring that no water seeps into the ground below the surface.
Take the clay and mix it with a small amount of water to make it easier to apply to the hole.
Step 5: The End
You should be able to set together a water filter in the wild now that you know how. The charcoal is responsible for the gray tinge in the cleaned water, but as long as you boil the water before drinking it, it should be safe to drink.
DISCLAIMER: This technique of water purification is intended for for use in SURVIVAL CONDITIONS, and it is not the ideal way of water filtration if you are in close proximity to civilisation. I am not liable for any accidents or medical events that occur as a result of using this instructable.

DIY Survival Water Filter | 12 Easy Steps to Make Your Own
Water makes up the majority of our body, including the brain (75 percent), bones (22 percent), muscles (75 percent), blood (92 percent), and many other organs. Even while we may talk for hours about the many advantages of water, when you’re out in the wilderness, you won’t be able to drink it directly from a stream or river. Just because something appears to be clean and fresh does not imply that it is. A water filter is required to remove germs and other impurities from the water. A failure to do so will jeopardize your health and chances of survival.
When you’re out in the wilderness, you can only rely on yourself and your own abilities to get through the day.
What You’ll Need:
- Rocks, sand, charcoal, grass, and a juice bottle (to use as a container)
Step 1: Put Holes at the Bottom of Your Filter
Specifically, we poked holes in the cap of the juice container in this instance. You’ll need to drill a few holes in the cover to allow for some airflow.
Step 2: Large Rocks
Large pebbles provide airspace for the survival water filtering process to take place properly.
Step 3: Medium Rocks
Limestone is an excellent example of a medium-sized rock. Its purpose is to aid in the absorption of dirt and germs from filthy water by the water filter.
Step 4: Small Rocks
It is also vital to use little stones in the survival water filter because they prevent dirt and other contaminants from entering through.
Step 5: Layer of Sand
Sand is the finest filter in your survival water filtration system, and it is the most effective. Remember to include a layer of fine-grained sand in your water filter design after you’re finished.
Step 6: Coals
In your survival water filtration system, sand serves as the finer filter. Remember to include a layer of fine-grained sand in your water filter design while creating it.
Step 7: Another Layer of Sand
The addition of a second layer of sand on top of the coals is required for even greater filtering efficiency.
Step 8: Fresh Grass
Grass may also be used as a replacement to cloth in your makeshift water filtration system.
Step 9: Egyptian Well
Make an Egyptian well before you use your DIY survival water filter for the first time.
Step 10: Get Some Water
You may start using your survival water filter with the water from the well.
Step 11: Pour Water into the Filter
It is necessary to repeat the procedure in order to make the water cleaner. Place the filter on top of a glass or cup, and pour the water through the filter into the glass or cup. Take pleasure in watching the layers absorb the water till it softly drips into your glass or cup.
Step 12: Drink and Enjoy!
Take a look at the video below, produced by Survival HT, to show how to construct a survival water filter in action: As stated in the video above, a DIY water filter should only be used if you are unable to find a more suitable and cleaner water supply elsewhere. Keep in mind that your health and well-being are your main priorities. After all, you’re a self-proclaimed survivor. We hope you found our instruction on how to create a DIY survival water filter useful and informative.

Wood filters, hot rocks, and seven other ways to purify water in the wild
This article was first published on the website Outdoor Life. In an emergency situation, finding and disinfecting enough drinking water to meet your needs is one of the most important survival considerations. If you find yourself in a crisis position in the desert after being lost or in your own house after a natural disaster, remember that the human body can only survive for three days without any kind of drinking water. It’s a good thing there are plenty of water sources available across much of the world, as well as several methods of disinfecting the water.

Finding a water source
Original publication of this story may be found atOutdoor Life. Finding and disinfecting enough drinking water to meet your needs is one of the most important survival considerations in an emergency. If you find yourself in a crisis position in the desert after being lost or in your own house after a natural disaster, remember that the human body can only survive for three days without any drinking water. The good news is that there are plenty of water sources available across much of the world, as well as several methods for disinfecting water.
Find out by following along here!
Boiling
Give those pathogens a death bath by drowning them with it. Tim MacWelch is a well-known actor. Water should be boiled in order to eliminate any parasites, bacteria, or other pathogens present. This is the most reliable method of killing pathogens in water. Although boiling will not completely eliminate all types of chemical contamination, it is still one of the safest techniques of disinfection available to us today. Most organisms will be killed in five minutes of a rolling boil, but ten minutes is preferable for safety.
It is possible to boil in a metal, ceramic, or glass container over an open fire or on a stovetop.
It’s possible that this container is a rock depression.
Distillation
A solar still, such as this one, will assist you in collecting water from the ground. Tim MacWelch is a well-known actor. In the aftermath of a disaster, your water supply can become contaminated with radiation, lead, salt, heavy metals, and a variety of other toxins, and attempting to filter them out will simply cause damage to your pricey water filter. The alternatives are limited in a situation when the only accessible water is potentially hazardous to human health and safety. Water distillation is the most secure method of disinfection.
Distillation will not eliminate all potential pollutants, such as volatile oils and some organic compounds, but it will remove the majority of heavy particles that would otherwise remain.
Making a steam distiller using a coffee grinder is a quick and easy method to prepare for disaster survival circumstances at home.
Survival straws
Survival straws can filter water just before it hits your mouth, saving you time and effort. Tim MacWelch is a well-known actor. The straw kind of water filter is one of the tiniest and lightest water disinfection products to have recently entered the market. Newer types may be used in the same way that a drinking straw would be, and they can also be connected to the drain valve on a water heater to clear out any water that may have accumulated in the heater following a disaster. They may also be attached to a garden hose in order to filter the water that passes through it.
Most
Filters
Gravity-fed filtration systems, such as this one, are most suited for situations when you are not in a hurry. Tim MacWelch is a well-known actor. Pump-action water filters and drip/suction water filters are the two most common types of water filters in use today. The former employs a pump to drive raw water through a filter cartridge, whilst the latter does not. The latter are filter cartridges that operate on a gravity drip principle (similar to an IV bag) or that are installed in line with hydration bladder hoses to filter water.
The Katadyn Pocket filter has been my go-to for years and continues to be so.
Ceramic screens out bigger pathogens, whereas silver kills or disables tiny organisms such as viruses and bacterium The majority of filters of this type will pump.
Ultraviolet light devices
UV radiation may destroy tiny organisms, however it is best used on pure water to have the most effective results. Tim MacWelch is a well-known actor. Small organisms are particularly vulnerable to the harmful effects of ultraviolet radiation. Using it as a disinfection method, it has proven to be remarkably efficient. Hand-cranked water purifying devices such as theSteripen Sidewinder, which does not require batteries, destroy the DNA of illness-causing microorganisms in a matter of seconds.
When dealing with water that contains huge floating particles (which germs can hide behind or inside), these devices will not be 100 percent effective, but they will be successful when dealing with clean water of doubtful origin.
Solar water disinfection
Although it appears to be simple to cure water with sunshine, there are a few disadvantages. Tim MacWelch is a well-known actor. Solar water disinfection (abbreviated SODIS) is a water treatment process that disinfects water by utilizing the sun’s radiation. The most often used procedure is to expose plastic bottles full of polluted water to the sun for at least one day, preferably longer. Almost all biological threats in water are killed or damaged by the sun’s copious ultraviolet radiation.
Because it’s simple to use, it’s affordable or even free, and it provides effective bacterial and virus disinfection (albeit not comprehensive or guaranteed).
Furthermore, the process does not make use of potentially hazardous substances and does not need regular monitoring. However, there are certain issues with the methodology. You’ll need bright, sunny days.
Disinfecting tablets
Depending on your condition and the pills you choose, you may have to choose between speed and flavor. Tim MacWelch is a well-known actor. The Micropur pills from Katadyn and the iodine tablets from Pottable Aqua are two of the most frequent and popular water disinfection tablets on the market. They are both capable of doing their jobs well, yet there are some disparities between them. In the case of purification tablets, the shelf life of the product should be taken into consideration when equipping a cabin, cave, or bug-out bag with the product.
That’s not awful, but Katadyn’s Micropur pills have a shelf life of at least two years.
When it comes to speed, Potable Aqua is unquestionably the best option.
Household chemicals
Either bleach or iodine can be used to disinfect water with acceptable results if they are used properly. Tim MacWelch is a well-known actor. Either bleach or iodine can be used to disinfect water with acceptable results if they are used properly. Generally speaking, the amount of chemical you use will be determined by the quality and temperature of the water you are using. The amount of disinfection required for cold or muddy water is somewhat more (four drops per quart) than for warm or clear water (two drops).
Then, turn the bottle upside down and unscrew the cap a turn or two at a time until it comes off.
Close the bottle tightly and wipe the outside of the bottle with a clean cloth.
Build your own filter
Filters constructed of wood have the potential to revolutionize the water filtration industry throughout the world. Tim MacWelch is a well-known actor. Those survival books with a water filter built out of charcoal-filled jeans hanging from a tripod are all too familiar to most of us. We are sorry to break your bubble, but that system is not a dependable source of information. Although it will filter out bigger particles, don’t expect bacteria- and virus-free water to emerge from this gadget.
Because of its structure, the sapwood already has a filtering activity in the live wood, preventing air bubbles from forming in the tree’s sap.
Some humanitarians are considering conifer wood as a potential filter material for this sort of filter.
Drink it raw
Untreated water is dangerous, but if you’re about to perish from dehydration, it can be your last alternative to save your life. Tim MacWelch is a well-known actor. Drinking untreated water is unquestionably a gamble. It is possible that even in the most pristine wilderness locations, the water might be tainted with microorganisms that cause gut discomfort. Drinking unprocessed water is dangerous at best unless you are fortunate enough to come upon a spring that is pumping pure water from the ground’s natural water table into the spring.
However, there are always exceptions to the rule. If you are on the verge of dying from dehydration and you are unable to treat the water, drink it nonetheless. It is preferable to be alive and ill by diseases than to be dead and unaffected by pathogens.
Bonus: build a water bottle survival kit
Choose a bottle with a large opening to make it easier to remove the things. editor(s) of Outdoor Life Online An empty bottle of water can be an extremely precious commodity to a person who is thirsty, but it is not just the water that has value; the bottle itself can serve a variety of functions. One of the most practical use is as a container for a survival kit. Here are some things to put in your bottle, whether it’s made of plastic or metal.
The gear
The components of your water bottle survival kit might be complicated and diversified, or they can be straightforward and practical. Whatever you decide to include in the kit, it’s a good idea to have a significant amount of redundancy. When your life may be dependent on a little collection of equipment, having a backup plan is always a wise decision.
- A folding knife and/or a tiny multitool are recommended. Button compass with liquid filling
- Batteries for a small LED flashlight or squeeze light, with an extra set of batteries
- A lighter, a ferrocerium rod, and tinder tabs are all included. water purification pills in the amount of 40
- Signaling with a mirror and a whistle a blanket for outer space
- A magnifying glass (for use as a backup fire starter)
- 550 cable, 50 feet in length
- Kit for fishing, which includes: 30 yards of monofilament line, 10 bait keeper hooks in a variety of sizes, and split shot
- 2 big and 2 tiny steel safety pins
- 4 steel safety pins A little first-aid kit is included. a few feet of duct tape (which might be wrapped around the bottle itself)
- A pair of scissors When the bottle is being used to carry liquid, a little bag to keep all of this equipment together
The bottle
Water bottles made of stainless steel with a single wall are one of the most innovative pieces of outdoor equipment to enter the market in recent years. This tough vessel is not only crack- and crush-resistant, but it can also be used to boil water to make it safe to drink. It is also dishwasher safe. Important note, however: if you are boiling water in a metal container, the bottle must be constructed of either single-wall stainless steel or another fire-friendly metal, such as titanium, and must be free of any paints or coatings.
The heat will not pass through the vessel adequately, and the vessel will most likely explode.
If you go the route of
How to Make An Emergency Water Filter
The popular post-apocalyptic television program “The Walking Dead” included an episode in which a group of survivors discovered themselves without access to clean water in an unknown environment. To begin, the character Rosita takes an empty plastic bottle and cuts a hole in the bottom of it before filling it with sand and stones. She then proceeds to carefully pour turbid water from a nearby stream through it, a process that takes many minutes. The necessary step of sterilizing the water after filtering (whether through boiling, disinfection with a chemical agent such as bleach, or UV exposure to sunlight) was not shown in the episode.
It is critical to seek out the purest water possible, and this is especially true under adverse conditions.
Materials Needed
What Supplies Will Be Required:
- A plastic bottle or other food-safe container of identical size and shape
- Yet another clean-water storage container
- Clean cotton or cheesecloth
- A coffee filter or a porous fabric
- Charcoal
- Sand (both fine and coarse)
- And other materials Gravel or pebbles are used as filler.
Step 1 – Cut Bottom Off
Cut away the bottom portion of the bottle into which you will be inserting the filter material with scissors or a knife to make a clean cut.
Step 2 – Cut Drain Hole
To make a small hole in the cap, use scissors or a knife to cut a small hole in it. Instead of cutting off the bottom of the bottle for the previous step, cut off the top and poke multiple small holes in the bottom of the bottle if there isn’t a cap available.
Step 3 – 1st Layer: Straining Fabric
Using a fine cloth or paper fabric, fill the bottom of the bottle, such as a coffee filter, cheese cloth, or cotton stuffing. Sand and grass can also be employed in this early step of the construction process. Fill the bottom of the container with about 3 inches of grass clippings to filter out bigger particles and to assist give water a clean flavor due to the chlorophyll found in the grass. Fill the container halfway with water.
Then add 3-4 inches of extremely fine sand to finish up the job. Keep in mind that when collecting grass clippings, you should avoid using toxic or unidentified plants. It is not recommended to use highway department sand since it may include road salt and chemicals.
Step 4 – Break Up Charcoal
Take charcoal from a campfire or BBQ charcoal (do not use match or quick light type because it is drenched in chemicals) and smash it down into the tiniest pieces you can with a hammer or rock.
Step 5 – Layer 2: Pulverized Charcoal
Fill the bottle with approximately 3 inches of powdered charcoal. Cover the filter with another coffee filter if one is available to prevent the charcoal from being moved too much during the filtering process.
Step 6 – 3rd Layer: Fine Sand
Add a 2-3 inch layer of the finest sand you can locate and rake it into the ground. Filtering out particles in the water is accomplished by the use of this and following layers. It is not recommended to use highway department sand since it may include road salt and chemicals.
Step 7 – 4th Layer: Coarse Sand
Add a 2-3 inch layer of coarse sand or very little small pebbles to the bottom of the container.
Step 8 – 5th Layer: Fine Sand
Add an additional 2-3 inch layer of the fine sand on top of the first one. A water treatment system with many variable filter stages (such as a reverse osmosis system) guarantees that the majority of the particles present in the water are removed.
Step 9 – 6th Layer: Gravel
Add a 2-3 inch layer of gravel or tiny boulders to prevent the sand from being displaced by the water that is being put into the container.
Step 10 – Top Strainer
Bandanas or cheesecloth can be used to cover the top of the filter to keep it from getting dirty. This step is optional, although it is beneficial in straining out any big debris from the water and preventing the water from displacing the sand inside the filter as a result of the pouring.
Step 11 – PouringCollecting
Water should be poured carefully into the filter while it is being held above the second container. Make careful to wipe off or clean the container where the waste is collected. Ensure that the water is poured carefully to avoid disturbing the filter layers too much or causing the filter container to overflow, which might result in unfiltered water overflowing into the collecting container.
Step 12 – Sterilize Water
However, even after you have filtered the water through several layers, germs may still be present in the water, necessitating the need for further treatment and sterilization. The quickest and most straightforward method is to bring water to a boil in a saucepan or kettle. You may also disinfect water by exposing it to the sun. Fill a clean, transparent plastic or glass container 3/4 of the way with filtered water and screw on the lid to seal it. Shake the water vigorously for thirty seconds to introduce extra oxygen.
The quantity of exposure that it requires is determined on the meteorological conditions at the time.
How to Filter and Purify Water for Traveling, Camping, and Survival
For the vast majority of people in the industrialized world, getting a drink of safe, clean, and tasty drinking water is as simple as turning on the faucet. Outside of the comfy confines of one’s own house, however, obtaining potable water can be more difficult and time-consuming. Perhaps you went hiking with all of the necessary equipment, but you just did not bring enough water with you on the trip to keep you hydrated. Alternatively, you may be traveling in a developing nation where you have been advised not to drink from the tap.
In these conditions, how would you go about obtaining safe drinking water? It is possible that the most appropriate approach will differ for each individual.
The Risk and Consequences of Drinking Contaminated Water
Water that is safe, clean, and tasty is as simple as turning on a faucet for the vast majority of people in the industrialized world. The process of obtaining drinkable water outside of the comforts of home, on the other hand, might become more difficult and time-consuming. Perhaps you went hiking with all of the necessary equipment, but you just did not bring enough water with you on your journey. Another scenario is that you’re traveling in a developing country where you’ve been advised not to drink from the tap water supply.
In these conditions, how would you go about procuring safe drinking water?
Does All Water Need to Be Treated?
In the wild, rainfall that has been collected in clean containers, as well as snow that has been melted, is typically considered safe. The water you gather in the woods, whether by transpiration or a still, is nearly always safe to drink (provided that the plant itself is not harmful, of course). It is recommended that you filter and/or purify any water collected by any other means, such as a stream or lake (flowing water is preferable to stagnant water, but it is still not foolproof), dew, or any other source.

Purification vs Filtration
It’s important to understand the difference between filtration and purification when it comes to water purification when it comes to locating and drinking water. They are not interchangeable terms. Water filtration is the process of removing trash and certain microorganisms from water by the use of a sieve, which is a sort of cloth or mesh net through which the water runs. Water purification is a procedure that uses chemicals or ultraviolet light to render bacteria and other hazardous agents inactive.
Sometimes water necessitates the use of both of these procedures, and other times it necessitates simply one.
If you’re traveling through Africa and believe you’ll simply need a filter, you might wind up contracting a fatal illness.
Water Filtration
Using a water filter, especially one that has been commercially tested (as opposed to the do-it-yourself backwoods kind), can effectively eradicate certain microorganisms. However, this is not the case. Filters may remove protozoa and bacteria from water, but they are unable to remove viruses that are present in the water because they are too tiny to be caught by the mesh of the filter. Water in the United States and Canada is generally considered safe for backpacking and survival purposes when only filtration-only methods and devices are used; this is especially true in mountainous environments.
Water that has been filtered also has the best flavor. Your water will have a natural flavor.
Water Purification
Water purification renders H2O safe to drink by deactivating any dangerous organisms, including viruses, that are present. Purification, on the other hand, does not completely eradicate pollutants. Filthy water that has been cleansed is still dirty water, and it is likely that it will require filtration (that should happen first, actually). Purification is accomplished largely by the use of boiling, chemical agents, or ultraviolet radiation. If you are traveling outside of first world nations, where viral illnesses are more frequent, you should take extra precautions.
Methods
You’ll find the most popular ways of water filtration and purification in the wild, as well as some of the advantages and disadvantages of each approach, listed here.
DIY Filters
Here are the most popular ways of water filtration and purification in the wild, as well as the advantages and disadvantages of each approach.
Commercial Filters
Straws for survival. A new generation of survival straws, the most well-known of which is the LifeStraw, has sprung into the market in the last 5 years or so. Drinking water directly via the straw (or water bottle with straw attached) is said to be safe due to the numerous filters that are housed within it, according to the concept behind it. The vast majority of straws available on the market are effective against bacteria and protozoa, but not against viruses. In most cases, they do not include any purifying agents.
Just make sure to double-check the specifications to ensure they meet your requirements before making a purchase.
This is not a good idea.
Boiling
Water purification in the backcountry is often accomplished by the use of boiling water. According to the Environmental Protection Agency, one minute of rolling boil will destroy all harmful organisms, including viruses. The duration is increased to 3 minutes if you are at a high altitude (more than 5,000 feet). Any metal or glass container will suffice, but if you don’t have any of those materials on hand, you may melt pebbles over a fire and set them in your container instead. When boiling water, one of the drawbacks is that it necessitates the use of a fire and consequently fuel, which is not always accessible (although it is more feasible if you read our article on how to start a fire without matches).
Chemical (Iodine/Chlorine/Bleach)
Water cleansing in the backcountry is usually accomplished by boiling it. As stated by the Environmental Protection Agency, one minute at a rolling boil will destroy all of the harmful organisms, including viruses. The duration is increased to 3 minutes if you are at a high altitude (over 5,000 feet). Alternatively, if you don’t have access to a metal or glass container, you may melt pebbles over an open fire and place them into your container. When boiling water, one of the drawbacks is that it necessitates the use of a fire and consequently fuel, which is not always accessible (although it is more feasible if you read our article on how to start a fire without matches first).
It also causes evaporation and a loss of some water volume, which should be taken into consideration when planning a water supply system or project.
UV/Solar
SODIS. Solar water disinfection (SODIS) is a technique that uses the power of the sun to disinfect water and make it safe to drink. Believe it or not, if you have a transparent water bottle, you can simply leave it in direct sunshine for 12 hours (24-48 hours on overcast days), and the sun’s ultraviolet rays will destroy the majority (but not all) of the bacteria and microbes in it. Some experts recommend leaving water exposed for a full day regardless of the circumstances, simply to be on the safe side.
Because this specific ultraviolet (UV) approach does not necessarily eliminate all germs and viruses, it is best utilized for survival purposes only, or in regions where water is known to be safe (or at least safe-ish).
There are a variety of gadgets available that generate UV light artificially in order to kill germs and even viruses in the home.
Bottom Line: What’s the Best Method for Various Scenarios?
SODIS. When it comes to making your water safe, solar water disinfection (SODIS) is a great option. Yes, if you have a transparent water bottle, you may keep it in direct sunshine for 12 hours (24-48 on overcast days) and the sun’s ultraviolet radiation will destroy the majority (but not all) of bacteria and germs. Water should be exposed for a whole day, according to some experts, regardless of the circumstances. What you need is entirely dependent on you. Because this specific ultraviolet (UV) approach does not necessarily eliminate all germs and viruses, it is best utilized for survival needs only, or in regions where water is known to be safe (or at least to be safe enough).
To get rid of germs and viruses, there are a variety of gadgets on the market that artificially generate UV radiation.
