How to choose an emergency water filter?

Surviving in the wild can be tough and dangerous, and the last thing you want is to end up with no way to get clean h20 and get sick from a contaminated water source. That’s why you need a filter that can get rid of the most dangerous contaminants. The essential features to look for in one are its capacity, size, weight, effectiveness, and usability.

The first thing to check when purchasing an emergency filter is its capacity because depending on how much liquid you’ll drink. Choose one that’ll be able to produce enough for your daily needs!

Other critical factors are size and weight since you want to ensure that your filter isn’t too heavy and bulky to carry. You need a compact survival filter that can be easily carried in a backpack without slowing you down when you’re outdoors.

Always check the effectiveness of a filter in eliminating contaminants. Make sure that the one you’ve chosen removes bacteria, protozoa, and other impurities. Last but not least, pick an option that’s easy to use because when you’re in the wilderness, you want to be able to get clean water quickly.

Can a water filter remove viruses?

A standard filter cannot remove viruses as they are too small. 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 with ultrafiltration that uses a nanometer-rated filter. Nevertheless, those filters clog easily and create enormous backpressure.

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 and store it in a dark, cool, and dry place.

If you don’t want to store large amounts of liquid or 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. Its powerful UV protection removes up to 99.99% of major contaminants.

Keep in mind that this is an ultraviolet system, and it can’t work without electricity so it won’t be useful outdoors on most occasions.

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 from 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.

How can I filter my water without a filter?

There are many options to filter water with a purifier, but most are not as effective. The most common way to do so is by boiling the water for a couple of minutes because high temperature kills any living bacteria. Still, it won’t eliminate 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 since the way you clean water is with chemicals.

Most people don’t like or understand this method, but pure bleach removes many impurities in water, and so does Calcium Hypochlorite in 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 – specifically, one that’s clean, free of contaminants, and safe to drink. When checking out emergency filters for your next adventure, keep everything we’ve mentioned above in mind to find a high-quality, effective filter that meets all your expectations and needs.
