New demonstration item at EcoHouse: the LifeStraw personal water filter

Green Venture recently received a donation of Lifestraw Personal Water Filters. The personal water filters, which look like a baton tube with a filter camp on the end, remove bacteria such as E.Coli, Giardia and Cryptosporidium from water in a natural setting. Each filter has the capability to make up to 1,000 liters of contaminated water safe to drink. They are used in third world countries to provide access to clean drinking water.

In Canada, the most likely application is use in a natural setting (hiking, backpacking, camping, etc.), permitting one to drink directly from streams and lakes or from any container. They also have travel and emergency preparedness applications. Apparently you can buy a specially-designed water bottle to enclose the straw, although ours didn’t come with that.

Green Venture staff used the Lifestraws during the 2017 summer camp season, as part of our off-site emergency supply kits.

By reducing fuel consumption necessary to boil and purify water, the filters also have the possibility of reducing one’s carbon footprint, especially in area without a municipal water filtration system.

It’s a very interesting contrast to a water filter we actually built here at EcoHouse in 2008- as part of a CAWST workshop.  In those days, the workshop instructors showed everyone how to make DIY concrete forms to hold water filters for a village water treatment system.

The Lifestraw company also contributes a portion of proceeds of sales of the Lifestraw to providing clean water to schools in Kenya and India.  http://followthelitres.com/

If you’d like to see the Lifestraw, please visit EcoHouse and ask one of our education staff to show the new demo item.
