Frequently Asked Questions

What is the best emergency water filter?

There is a clear winner when we’re talking about emergency water purification, and that’s the Survivor Filter PRO. This unbelievable product removes 99.9% of most impurities while reducing almost all heavy metals and chemicals. Quality and reliability are wanted by everyone when it comes down to emergency water filtration systems, and this one will never disappoint.

Can a water filter remove viruses?

A standard filter cannot remove viruses as they are too small to do so. Most physical filters will remove contaminants on the micron scale. However, viruses can be even smaller. There is a possible way to have virus protection, and that’s with ultrafiltration that uses a nanometer-rated filter. Nevertheless, those filters clog easily and create enormous backpressure.

dirty water needs filter

What is the best water filtration system for emergencies?

The best emergency water filtration system is Sawyer MINI, with its compact and lightweight size, which makes it a great option when you’re in the outdoors, and that’s where most emergencies will occur. This survival water filter removes 99.9% of all bacteria while filtering giardia and cryptosporidium. It’s easy to set up and even easier to use with the provided straw filter that enables you to drink it directly from a water source.

How do you filter water in an emergency?

Emergency drinking water that should be part of your anti-disaster prep comes with 20 years of shelf life, which means it’s safe to drink when stored properly. You don’t necessarily have to filter it, but make sure it isn’t exposed to direct heat and sunlight in a plastic bottle, store it in a dark, cool, and dry place.

If you don’t want to store large amounts of liquid or you don’t have the space to, you can always opt for a filter for emergency preparedness. 

Which water filter pitcher removes the most contaminants?

If you’re looking for a filter that removes most impurities, the Express RO UV Sterilizer is what you need. All of Express’s filters are specifically engineered to work together, to produce the safest and best tasting h2O you’ll ever drink.

How do you purify water for survival?

The easiest way to purify it in the wilderness is to boil it, provided you have the equipment to do so (a.k.a. survival kit), plus a campfire. Another option is to have a filtration system with you.

That might not always be the case, but if you have purification tablets, you’ll have a way to drink clean water, even if it’s not necessarily the best tasting – method. Almost all methods require you to carry h2O or have a water source nearby.

Still, in case of an emergency or a severe natural disaster, you can evaporate water in the ground. Dig a hole and insert a container on the bottom with a cover that will allow it to evaporate from the soil upwards, condensing on the cover and dripping into the container.

Does LifeStraw filter radiation?

Radiation can enter the water supply due to both natural and man-made sources. We can find small traces of radioactivity in nearly all drinking liquids. There is no simple way to remove radiation from it.

Still, the combination of treatment methods, including carbon filtration, ion-exchange water softening, and reverse osmosis, is most effective yet not entirely accurate. That’s why LifeStraw personal water filter can do wonders for your survival in the wilderness.

How can I filter my water without a filter?

There are many options to filter water with a purifier, but most of them are not as effective. The most common way to do so is by boiling the water for a couple of minutes because high temperatures will kill any living bacteria. Still, it won’t get rid of contaminants such as heavy metals, salts, and chemicals. Pasteurizing water is another option in which you heat water to 149 degrees for several minutes, removing bacteria, heavy metals, and chemicals.

Your easiest option is solar water disinfection in which you leave the liquid in plastic bottles on a dark surface in the sun to increase temperature, and the water gets somewhat clean. Last but not least, this option shouldn’t be used often or for an extended period of time since the way you clean water is with chemicals.

Most people don’t like or understand this method, but pure bleach gets rid of a lot of impurities in water, so does Calcium Hypochlorite in the event of an emergency. Water filtration is no joke, use these options if you don’t have a proper way to filter your water.

Final Words

One of the essential things to survive in the great outdoors is water – more specifically, one that’s clean, which is free of any contaminants, and safe to drink. When you are checking out emergency filters for your next adventure, keep everything we’ve mentioned above in mind so that you can find a high-quality, effective filter that meets all your expectations and needs.
