LifeStraw Personal Water Filter for Hiking

Every vehicle, including our RV and boat, has a LifeStraw. These are simple to keep on hand in case of an emergency. They’re simple to drink from and keep you secure from unsafe water sources. Everyone should have a couple of them!

The Lifestraw has been a game-changer for me; I have one in my vehicle and one in my hunting bag, and while most streams where I live are safe to drink from, it’s still a good idea to have one. It’s quite simple to use and lasts a long time. It’s something I’d recommend to anyone who spends a lot of time in the woods.

Safe & extremely reliable filter!

I took it with me on a camping trip through Maine’s Bigelow Mountains. I was fine with it when I ran out of the water I had brought. Pack a wide-mouth container to fill with any water you come across. I drank from a disgusting-looking crack packed with brown sludge on top of one of the lower peaks. I reasoned that this would be safe but taste awful. But the taste was like fresh water! It’s superior to any tap. Take my word for it: I’m from Maine, and I’ve had enough of water straight from mountain springs. One word of caution: getting started might be difficult. You’ll have to soak to prove it. If that doesn’t work, try blowing into it.

Get one for your outdoor trips and one for your bug-out bag, which should be in everyone’s home in the event of a natural disaster.

In an emergency, the LifeStraw Personal Water Filter can save your life. I’ve tried it with topwater, and it seems to work. However, I would recommend the following based on some of the reviews. Before using the filter, soak it in water for about ten minutes and cover it with a piece of cheesecloth or a handkerchief. The water will flow more freely, and the cheesecloths will keep the filter from clogging.

It is a little silly that it stopped operating after I dropped it from my mouth while blowing water out of the tube, and it fell on the countertop.

There was no impact at all; it was only about 12 inches. If it can’t withstand any form of impact, it’s risky to use as your sole source of water in the woods. So the sole reason for this negative evaluation is because of that.

Is there a date of manufacture on it or do we have to replace these every 5 years?

Five years from the manufacturing date, which should be printed on the packaging. The last ones I got from Amazon were over their expiration date, but the manufacturing and expiration date were no longer visible on the packaging. I called Lifestraw, and they were a few years out of date, according to the batch of the product. If you go to your local gaming or sporting goods store, you will see that they all have a production date, an expiration date, and a batch number. Remember that you get what you pay for, and saving a few bucks by buying from sellers that aren’t exactly trustworthy and sold you unusable, expired goods isn’t a good deal in the end. If it doesn’t have a date you can find on the packaging, then its most likely been removed and either out of date or close to

Does it filter out chemical toxins?

Chemical pollutants can only be removed/ADSORBED on a molecular level. That’s where charcoal filters come into play. Consider it as a series of filtration stages. Bandana increases filter life by removing particles, pollen, plant fragments, and algae reduced to 50 microns, and cotton adsorbs chemicals on its surface. If you bandana filter first, it extends your filter’s trip life and flow rate! Then pass over/filter through finer and finer crushed activated charcoal stabilized by separating membranes to get rid of bacteria, protozoa, and large viruses (0.1 micron or 100 nanometers. But viruses like Norovirus (23 to 48 nanometers) can go right through. This device will absorb chemicals and many fine viruses down to 17 nanometers. Keep in mind that viruses with a diameter of 10 to 27 nanometers usually exclusively infect plants, are smaller, and prions that cause mad cow disease with a diameter of 2 to 10 nanometers are even smaller! Depending on the virus type, you can now treat with a chlorine or bromine water purification tablet (the best are chlorine dioxide tabs), which will damage the virus cells. So, there are already pondering how to carry out the gross filtration-microfiltration-charcoal filtration-chemical treatment.

Is the LifeStraw compatible with seawater?

The Life Straw will not remove salt from seawater. Desalinators, which can create drinking water from saltwater, may be purchased on Amazon for roughly $250- $300. Life Straws, unfortunately, are unable to remove salt or hazardous substances from contaminated water.

What is the product’s shelf life?

I wrote Lifestraw and received the following response that  LifeStraw® does not have a shelf life; they have tested it in their water lab for up to 5 years without apparent deterioration. It contains no organics or other unstable materials.

Will it taste like water or urine if I filter urine?

The filtered urine will retain salt and urea, as well as numerous other chemicals your body is trying to expel, so it will still taste like whatever urine tastes like. Many people have attempted to drink their urine in extreme survival situations. Up to a point, that’s fine. However, your urine will become heavily concentrated as your dehydration progresses, turning dark and even vicious. Urine is best consumed early in a survival crisis since it is less concentrated and less harmful. That way, you’ll be able to conserve what water you do have for a longer period. Of course, most people will use up all of their water before resorting to drinking urine. On the other hand, drinking concentrated urine is probably worse than not drinking any at all. Furthermore, urine is sterile inside your bladder but not as it passes through your urethra.

There are better options on the market

Get yourself a Sawyer-Mini. On camping vacations, I’ve used both. To suck water through a Lifestraw, you’ll need steel jaws. However, you won’t rip out your fillings attempting to retrieve water with a Sawyer or other pump/squeeze filters. Furthermore, you must lie on the ground, whereas other filters include collapsible pouches as well as a straw if the pouch breaks.

You should view actual footage of people that use these regularly before deciding. Everyone moves to a filter that uses a pump or squeeze to filter the water.
