Preparers can chat until the zombies get home about the best ways to survive the apocalypse, but there’s one thing everyone both in and out of the bush can be concerned about. Okay, in the event of a natural disaster, there is nothing more important than having enough water. Humans can only survive three days without water, so without water you are sunk.

If you have space, you should try to have plenty of bottled water on hand. Stephanie Fox of the American Red Cross recommends having “at least a gallon of water per person per day” for three days if you have to evacuate and two weeks if you are stuck at home. “But once that’s over,” says former Army Special Ops captain and survival specialist Mykel Hawke, “you have to have a way to resupply yourself. As homesteader and survivalist Morgan Rogue of Rogue Preparedness explains, “The disaster itself is only part of it. We also have to consider the consequences, ”during which floods, power outages, broken water pipes and supply chain disruptions can cut you off indefinitely. This is where water purification comes in. There are several ways to do this, but the most convenient are to boil it, strain it and purify it with lozenges. Most of the experts we spoke to recommend a combination of these methods. And just to be clear, we’re not talking about a pitcher with a charcoal filter that you fill from the tap – these make your water taste better, but they’re useless against viruses, bacteria, and most. other harmful contaminants from questionable water sources. We’re talking about how to purify water from potentially dangerous sources, so we asked nine experts in the survival field to recommend the best products to keep you safe and hydrated in the event of a disaster.

AOFAR AF-374 Magnesium Fire Starter (two-pack)

If you have access to a fireproof container and a source of fire, boiling water is a very effective way to remove contaminants. The National Park Service recommends that you keep the water boiling for at least one minute if you are below 6,500 feet in elevation and three minutes if you are above 6,500 feet. “You will need clean water not only for drinking, but also for washing dishes, laundry, cleaning, personal hygiene and cooking,” says Hawke. He suggests that you use a “good big pot” in the fireplace (if you have one) or outside on a grill or portable stove, and he recommends that you have back-up lighting methods like lighters or magnesium bars. For a convenient and portable all-in-one solution, he likes the Kelly Kettle, which is a stove and kettle that uses natural fuel (like twigs, grass, or whatever you find around you) to boil water or rehydrate food. in a few minutes.

Aquatabs water purification tablets

Another simple and inexpensive way to purify water is to use purification tablets. There are two main types: those that use iodine and those that use chlorine dioxide. (Iodine should be avoided by pregnant women and those with shellfish allergies or thyroid issues.) Both will kill most harmful contaminants in about 40 minutes, but only those made with chlorine dioxide will kill this. called cryptosporidium, a parasite that causes gastrointestinal and respiratory illnesses. , although it will take four hours to do so. And both can leave a somewhat unpleasant aftertaste. Iodine is said to be worse, but it can be largely relieved with vitamin C or ascorbic acid tablets, which are sometimes sold with the purification tablets. Thomas Coyne, the owner and lead instructor of the highly respected Thomas Coyne Survival Schools, recommends Aquatabs, which are made from chlorine dioxide. One tablet will purify two liters of water in about 30 minutes and have a shelf life of five years. Rogue likes these as well as those from Potable Aqua, iodine-based tablets with a four-year shelf life. The PA + package contains 100 regular tablets and 100 taste enhancing tablets, and it treats up to 25 liters.

Berkey Filters Big Berkey Gravity-Fed Water Filter

Filters are another versatile option for water purification, and many experts, including John Ramey of the Prepper the Prepared site, recommend a combination of tablets and a filter. “Everyone does well on their own, but everyone has weak points, so the one-two move is the way to go,” Ramey said. But if you only have one thing, he adds, go for a filter “because it will treat a lot more water than tablets.” A gravity filter uses gravity to do the job and usually consists of a bag that you fill with water and hang somewhere, although there are freestanding styles that sit on flat surfaces. They are great if your water source is deep enough for easy collection in a bag, but if you are collecting water, for example, from a shallow stream, you will find it easier to use a pump filter. . Straw style filters are great for individual use and are lightweight and easy to carry with you. The most popular gravity filter is the Berkey, which can sit on a flat surface and is loved by many of our experts, including Snape, Lisa Bedford (aka “The Survival Mum”) and the popular YouTuber Who’s Who. calls Prepper Potpourri. It costs a bit, but the fact that it can filter 6,000 gallons of water before needing to replace the filter makes the faithful say it is worth it.

LifeStraw Flex Advanced Water Filter with Gravity Bag

Nettie David of Preppers Survive recommends this gallon gravity bag which removes lead, parasites, bacteria and chemicals and can be used with a straw, plastic bottle or in-line hydration bladders.

Mini Sawyer Water Filtration System

The Survival Mom uses and recommends a similar but even smaller and cheaper option called the Sawyer Mini, which doesn’t require gravity. It consists of a small filter that can be attached to the included pouch or your own water receptacle (like a plastic bottle) and sipped through the supplied straw.

LifeStraw Personal Water Filter
Roving Blue O-Pen Ozone Purifier

The LifeStraw and the O-Pen, two of Hawke’s favorites, are as sleek and simple as it gets. While he recommends you use them with a transportable water source like a canteen or a bottle, both essentially allow you to sip directly from a body of water like a stream or river. The LifeStraw can filter up to 1000 gallons of water and even filter microplastics down to one micron. The O-Pen looks like a pen and weighs just over an ounce. It uses gaseous ozone and can filter 16 ounces of water in under a minute. Its rechargeable battery can filter approximately 25 liters per charge.
