FILTRATION BOTTLES & POUCHES
To make it easier to take water with you. There are water filtration bottles and squeeze pouches. Just screw into your devices to use as a gravity or squeeze bottle system. The Squeeze Kit is the ultimate tool for your bug-out-bag, emergency kit or overseas travel. Cleaning water down to a filtration level of 0.05 Microns, that's at a cellular level. This is based on the Survivor Filter Pro Squeeze. There are many choices out there, including LifeStraw and Sawyer. Always read the reviews and the information.
These bottles and pouches work on the same principle and the filters straws. Some are specifically made for the device it comes with, like the filtration bottle and some you just screw onto the included pouch of a threaded bottle. Please remember not all bottles are threaded the same.
Also, some filtration systems will have different levels of filtration, double, triple and so on.
Pay particular attention the the micron level as well, The smaller the micron number the better. Try imagining microns like a sieve. A 5 micron water filter will sieve out particles that you can see – but all the other smaller particles will pass through it into your drinking water. By contrast a 1 micron filter will remove particles not visible to the naked eye. I would rather have nearly all the particles filtered, wouldn't you?
