The LifeStraw Personal Water Filter is a compact, lightweight and portable water filtration device designed for outdoor enthusiasts and travelers. It can filter up to 1,000 liters of water, removing 99.9999% of waterborne bacteria, protozoan parasites, and microplastics. This makes it an ideal tool for hiking, camping, travel, and emergency preparedness.

If you were to pee into a bowl and use the LifeStraw filter, the filtered urine would still taste like urine, as the filter is not designed to remove salt and urea from the liquid. While drinking urine may be a last resort in a survival situation, it is important to note that the concentration of toxins in the urine increases as dehydration sets in. Therefore, it is recommended to drink urine only in the earliest stages of a survival situation, as it may be less concentrated and less toxic at that time.

LifeStraw Personal Water Filter for Hiking

The LifeStraw Personal Water Filter is designed to remove waterborne bacteria, protozoan parasites, and microplastics, but it is not specifically designed to filter out chemical toxins. To filter out chemical toxins, you would need a filter that can adsorb the toxins at a molecular level, such as a charcoal filter. It is possible to use a combination of filters, such as a bandana to remove larger particles and extend the life of the LifeStraw filter, followed by a microfilter and a charcoal filter to remove bacteria, protozoa, and chemicals. Additionally, water purification tablets can be used to denature virus protein capsid coat or spiky envelope, depending on the type of virus. However, it is important to note that no single water filtration method is 100% effective against all types of contaminants, and it is always best to use multiple methods to ensure the water is safe to drink.

What is Microfiltration membrane?

Microfiltration membrane is a type of membrane used for filtration purposes, typically for removing small particles and microorganisms from a liquid or gas. It is made up of a thin layer of material with tiny pores or channels, usually in the range of 0.1 to 10 microns in size, that allow liquid or gas to pass through while blocking larger particles and microorganisms. In the context of the LifeStraw product, the microfiltration membrane is a key component of the water filtration system that removes bacteria, parasites, and other contaminants from water, making it safe for drinking.

What are the alternatives to this membrane, what are their advantages and disadvantages?

There are several alternatives to microfiltration membranes for water filtration, each with its own advantages and disadvantages. Some of the common alternatives are:

  1. Reverse Osmosis (RO) Membrane: This type of membrane uses pressure to push water through a semi-permeable membrane that removes dissolved solids, salts, and other contaminants. The advantages of RO membranes are that they can remove a wide range of contaminants, including heavy metals, dissolved salts, and minerals, and produce high-quality water. The disadvantages are that they can be expensive, require electricity, and generate wastewater.
  2. Ultrafiltration (UF) Membrane: UF membranes are similar to microfiltration membranes but with smaller pore sizes that can remove viruses and smaller particles. The advantages of UF membranes are that they can remove a wide range of contaminants and do not require electricity. The disadvantages are that they can be expensive and may require pre-treatment to remove larger particles and sediment.
  3. Activated Carbon Filter: Activated carbon filters use a porous material, typically made from coconut shells, to adsorb contaminants like chlorine, volatile organic compounds (VOCs), and some chemicals. The advantages of activated carbon filters are that they are affordable, widely available, and effective at removing certain contaminants. The disadvantages are that they can clog easily, require frequent replacement, and may not remove all contaminants.
  4. Ceramic Filter: Ceramic filters are made of a porous ceramic material that can remove bacteria and other contaminants from water. The advantages of ceramic filters are that they are affordable, do not require electricity, and can be cleaned and reused. The disadvantages are that they may not remove all contaminants, can be fragile, and may require pre-treatment to remove larger particles.

Overall, the choice of filtration method depends on the specific contaminants present in the water, the volume of water to be treated, and the available resources and budget.


I highly recommend the LifeStraw Personal Water Filter (2-pack) for anyone looking for a reliable and effective way to purify their drinking water. This product is compact and lightweight, making it easy to carry with you wherever you go, and the fact that it comes in a 2-pack makes it even more convenient for those who enjoy hiking with a partner or in a group.

One of the most impressive aspects of this filter is its effectiveness in removing 99.99% of all waterborne bacteria and parasites. This means that no matter where you are, you can feel confident that you’re drinking safe, clean water.

In addition to its effectiveness, the LifeStraw is incredibly easy to use. Simply fill up a container with water, insert the LifeStraw into the container, and start drinking.
