water purification

LifeStraw Personal Water Filter

Lifestraw
LifeStraw

The retired SEAL next door told me that filter straws were all they carried on missions through the desert. Good enough for me. I thought I would give the LifeStraw a try. My only hesitation is virus elimination. Apparently, not such an issue for us in North America. I would be more cautious if I were in the Afghan desert. The Lifestraw is rated to remove virtually all bacteria and protozoa parasites (more than 99.9 percent) that can contaminate water. The units also do a fine job of reducing any particulate matter in the water.

First stop was an open pothole in the Utah desert. Clear water, lots of moving organisms. Looked good. I was confident the filter would keep the fauna and silt out of my teeth. I pulled the 2 ounce, 1 inch diameter by 9 inch tube from a side pocket of the pack. Dipped in the edge of the water and sucked. It took a moment and a bit of effort, but once it started I got a fairly good flow of water. A refreshing gulp of neutral tasting water. Then the  procedure is to step back and blow air throw the unit to clear it after drinking.

Next stop: water flowing from a seep near Mr. Grandstaff’s Canyon. This time the LifeStraw was hanging around my neck by the lanyard. Easy to tip into the water once you crouch down. Another intense draw, but once the first flow started I could enjoy the really cool water. The only grumble being without a hose you have to lie down in the rocks at water’s edge to use the LifeStraw. So quit complaining and get a cup.

Good for 1000 liters (264 gallons) of filtered water. They also make a Family LifeStraw with a bucket to draw water and hose to filter 16,000 liters of water, enough to last a family of 5 for three years. In celebration of the U.S. retail launch, both Eartheasy and Green Beetle will donate one LifeStraw® for every ten sold.

SteriPEN Adventurer Opti Solar Powered

SteriPEN harnesses the power of ultraviolet light to make water safe to drink. It’s the same technology used by leading bottled water manufacturers, as well as major cities in the U.S., Europe and Asia to purify water.

SteriPEN’s UV light technology eliminates over 99.9% of bacteria, viruses and protozoa that cause water-borne illness. SteriPEN purifies 16oz. (0.5L) in just 48 seconds; 32oz. (1.0L) in just 90 seconds. All without any pumping, timekeeping, or any added aftertaste or chemical odor.

Add solar charging to the  Adventurer Opti for complete freedom on or off the grid. Solar charging clamshell case pulls double duty: recharging the rechargeable CR 123 Lithium Batteries and providing handy, secure storage for the purifier. The SteriPEN Adventurer Opti uses an optical eye to sense the water. This technology ensures safe use and provides purification in even the coldest of waters.

The new optical sensor doubles as a convenient LED flashlight. It’s a great backup light when camping or taking a night-time walk to refill your water bottle. The Flashlight mode is activated by pressing and holding the single button down for 3 seconds. The clear lamp cover focuses the LED light.
