The LifeStraw is an amazing example of a survival filter. This product removes 99% of bacteria and protozoa from contaminated drinking water sources such as surface fresheners, chlorine tablets, and water disinfectants. It also removes sediment particles that are toxic in nature and can pose a serious threat to human health.

The LifeStraw can also be used to filter extremely dirty water, such as mud or saltwater. It can filter up to 1000 liters of water in its lifetime, depending on the condition of the water source being filtered. If it becomes damaged somehow, you can simply replace it with a new one.

If you are concerned about plastic products leaching into your drinking water, you may want to consider glass filters instead. Glass filter options are available and their reliability and effectiveness is similar to that of plastic filters. The only drawback is that they are typically more expensive than other types of filters such as micron cartridges and carbon blocks.

Lifestraw is definitely the cheapest and most worth it when compared to all of the other water filtration systems. It also has over 75,000 reviews.

By the way, here is how to filter water in the wild.

The MSR Guardian Purifier is another high quality choice for a survival filter. It removes up to 99.99% of bacteria and protozoa found in contaminated water sources. It is also capable of removing sediment, chemicals, and heavy metals from the water before it reaches your body. These elements can cause serious side effects such as vomiting, diarrhea, and dehydration if consumed.

The filter can remove viruses as well with some modification. While it was manufactured specifically as a microfilter in order to remove these tiny particles from your drinking water, you may have to modify the filter in order to do so. This can be done by removing the first stage of the filter in order to reduce its pore size, thus allowing it to catch even smaller particles.

Another benefit to using this filter is that it removes 99% of pesticides and herbicides from water sources. This makes the water safer for consumption instead of potentially getting sick if you don’t do anything about the contaminants found in your drinking water. It is also capable of removing chemical additives such as chlorine that can be present in your drinking water supply.

The TRAVEL H20 is another great choice for a survival filter.

Freeing Your Filters from Contamination

In order to ensure that your water supply is clean, there are several things that need to be done beforehand such as:

Change out all the dirty bottles on hand. Wash and fill up all dirty bottles with clean drinking water, remove labels, and put them aside to be used later. Sanitize all bottles before filling up for drinking purposes.

Change out all dirty water bottles and filter cartridges. rinse all the dirty bottles and fill them up with clean drinking water, sanitize the cups, cups, and filter cartridges afterwards.

Check if there are any chemicals that are being used to disinfect the water or stored in tanks. If so, evacuate the area to ensure that no one gets sick from it.

DIY Filtration Methods

If you do not have a water filtration system shown above, you can use the 7 shelf filter as a LAST RESORT filtering method among many others. This will separate out most of the sediment particles found in the water and ensure that you get a cleaner form of water for your consumption.

Grit bottles can be used if there is still some sediment particles present in the water after passing through the 7-shelf filter. Simply pour the contaminated water into a bottle and shake it up, letting all of the sediment settle to the bottom of the bottle before drinking. 

This will also work with muddy or sandy waters as well in order to remove sediment from them before it enters your body.

Chemicals that are used to disinfect water can be avoided by adding a little bit of bleach or other sanitizing chemicals to the water before drinking it. This will ensure that you do not ingest anything harmful into your body. After adding these chemicals, shake up the bottle and let it sit for about 30 minutes before drinking.

Depending on how bad your water supply is, there are a few other methods that you can use to purify it. These include:

Boiling Water– This method removes most of the bacteria and protozoa found in contaminated water. Add water to a pot and heat it up to boiling, then let it sit for at least 3 minutes before consuming.

Solar Water Disinfection- This method uses the sun’s UV rays to remove bacteria and protozoa from contaminated water. Place your contaminated containers on a clear surface out in the sunlight without any other surfaces blocking it, like trees or other shadowed objects. Let it sit there for at least 6 hours before drinking if there is contamination present in your water supply.

Ultraviolet Light treatment- This method uses what is called artificial sunlight in order to disinfect contaminated water. The UV light will kill bacteria, protozoa, parasites, and other illnesses that can be present in your drinking water. Place your contaminated containers on a clear surface out in the sunlight without any other surfaces blocking it. 

Allow room for some room between the container and the close objects like trees or other shadowed objects. Let it sit there for at least 12 hours before drinking if any kind of contamination is present in your water supply.


There are many different types of water filters available in the market today, so you should do your own research in order to find the best filter that fits for you.
