Bag versus bottle? Puralytics' new approach to pure portable water

Summary:The Puralytics SolarBag is a refillable, 3-liter container that uses sunlight-activated nanotechnology to purify water in about three hours.

I cringe every time my husband puts bottled water on our shopping list for a big party we're hosting. Sure, I'd much rather have my guests chug H20 than beer, but I can't abide the waste implications of the empty containers.

That's why I'm going to do some research into the SolarBag, a new technology from water company Puralytics for purifying water on-the-go. The product could have implications for camping, international travel or for the emergency kit you're supposed to keep in the trunk of your car.

SolarBag uses sunlight-activated nanotechnology to remove bacteria, viruses and protozoa from water. As the image suggests, you could use the bag while camping to keep stocked up on water.

It takes about three hours for the SolarBag to produce 3 liters of fresh water in direct sunlight (four to six hours if it is cloudy). It can be used several times per day, and Puralytics said the bag can be reused hundreds of times before it needs to be replaced.

The SolarBag exceeds U.S. Environmental Protection Agency guidelines for water purifiers, according to Puralytics. "The versatility and performance of the SolarBag makes it the best water purifier on the market for remote and emergency applications," said Mark Owen, found and CEO of Puralytics. "It's light, simple to use, easily transportable and reliable."

Right now, SolarBag can be bought from Amazon (about $77) or from The Sportsman's Guide (about $80). It is available in 30 countries, where it is being used to help increase access to potable water in developing countries.

OK, so maybe SolarBar isn't appropriate for my husband's parties, but given that another one of his great loves is camping I might have to consider getting him one on the next gift-giving occasion.
