Emergency Water Purification

One of the most important needs in life and while buggin’ out is the need for water. At the minimum, a grown human adult needs at least 1 liter (about 1.06 quarts) of water per day. If water weighs 8.35 pounds/gallon, and you need at least 3 liters, then you need to carry a little more than 6.6 pounds of water in your bug out bag. However, if you are going to be constantly walking, then you will need even more than the minimum suggested. Instead of carrying all that extra weight on your back and shoulders, you should look into some kind of emergency water purification for your bug out bag.

Emergency Water Purification by Katadyn (Vario Multi Flow Water Microfilter)

Katadyn Vario Multi Flow Water Microfilter

The Katadyn Vario Multi Flow Water Microfilter is an excellent addition to any bug out bag. It weighs a mere 15 ounces, and is only 6 1/2 inches in height. That is smaller and lighter than any standard water bottle. Yet its output is a huge 2 quarts per minute. That means less work and less time filling up your bottles or your hydration bladder, and more time moving to where you are going. Another smart feature on this emergency water purification unit is that a turn on the head of the unit engages the ceramic filter, thus extending the life of the pleated glass fiber filter that you use in normal conditions. When the ceramic filter is engaged, the output slows to about 1 quart per minute. Inside of the fiber filter is a replaceable carbon core that keeps the water tasting fresh. Unlike most water purifiers, this one operates on a dual piston technology. This means that it is purifying the water while you pull the handle up, and also when you push the handle back down. The only downside to this unit is that the filter is only good for up to 500 gallons, or about 1875 liters. Hopefully your bug out bag does not see this much action.

Emergency Water Purification by Katadyn (Pocket Water Microfilter)

Katadyn Pocket Water Microfilter

The Katadyn Pocket Water Microfilter is the “Cadillac” of the water purification units. This water filter is the choice for the U.S. military, and expedition units. The water filter has a silver-impregnated ceramic element, that is effective against bacteria and protozoa. The Katadyn Pocket Water Microfilter filters out any microorganisms larger than 0.2 microns to provide you with the clearest, cleanest drinking water. This unit is a little larger than the previous one, but still a small 10 inches tall. It weighs in at just over a pound (20 ounces), but that is because it is made of more heavy duty materials so that it can handle being thrown around. This pump features a round handle which is more ergonomic than most units, and contains a cushioned base which makes pumping easier, regardless of the surface its set on. The output is about 1 quart per minute. That is slower than the previous model, but the reason is that the filter is better. The filter in this unit is good for up to 13,000 gallons, which is more than almost all other emergency water purification units. Also, this is the only water filter on the market with a 20 year warranty.

Either of these emergency water purification units are excellent choices for your bug out bag. Both units have been extensively tested by the manufacturer and various government agencies. I personally keep a Katadyn water filter in my bug out bag for the sole purpose of emergency water purification. There are other brands out there that cost less, but I believe that you get what you pay for.
