Gravity Fed and Collapsible Survival Water Filter Systems

The Best Survival Water Filter Systems Platypus GravityWorks Water Filter

If you’re setting up camp either solo or as a group, a gravity fed survival water filter represents an excellent choice for high quality water purification that packs flat, weighs virtually nothing, and is easy to carry.

The premise of gravity fed water filters couldn’t be simpler, effectively just a bag that you fill with water and hang from a branch, wall, or equivalent spot, before allowing gravity to do the work of purifying a questionable water source.

Whereas other survival water systems designed for portability depend on either suction (in the case of ‘tube’ style filter straws, bottle filters, or bladder solutions) or some form of hand pump to pass water through a filtration element, gravity fed survival water filters operate in the same way as large home emergency filters such as the Berkey range, where the water is ‘pulled’ through the filter by gravity, leaving you with a clean and drinkable end-result at ground level.

The fact that this kind of survival water filter is able to fold down to a negligible size when not in use means that it’s also a great solution if packing space is at a premium or as a low-profile solution for storing with your emergency preparedness supplies at home.

As with all survival equipment, the best emergency water filters need to be versatile as well as durable and reliable and the Katadyn is compatible with hydration bladders as well as offering the ability to convert to a camp shower with the addition of an adaptor.

A great addition to a comprehensive bug out bag or vehicle packing list as well as a versatile and low profile backup in your home preparedness supplies, the Katadyn Gravity Camp is a dependable survival water if you need a solution that can be carried easily and setup quickly.

As soon as you’ve collected your water and hung the filled reservoir from a tree branch or similar raised area, 1.75 liters of filtering per minute means you’re looking at around 2 and a half minutes until you’ve got a full reservoir of clean water ready for drinking, cooking, or washing.

The reservoirs themselves are antimicrobial and BPA free and the design of the system is optimized to reduce any taste once the water is filtered.

A hollow fiber microfilter is responsible for cleansing the water that you collect and is capable of removing 99.9999% of bacteria and 99.9% of protozoa, including giardia, cryptosporidium, E. coli, salmonella, cholera, the Platypus GravityWorks meets all EPA guidelines.

Portable Survival Water Filters

The Best Survival Water Filter Systems Sawyer S3 Water Filter

If you find yourself in an emergency situation that finds you away from home, the ability to access clean and safe drinking water becomes more important than ever as you won’t be able to fall back on a stored supply of bottled water or other home preparedness hydration solutions.

The priority for a portable survival water filter should always be on striking balance between size (and the ability to pack or carry easily given your specific requirements) and the ability to effectively purify as many potentially harmful elements out of your drinking water as possible.

best survival water filters and survival water filter systems katadyn hiker pro microfilter
