You would be taking a significant personal risk to your health drinking from this pond, but for state-of-the-art filtration technology now available in extremely small form factors and at a very reasonable price.
The filtration system reduces contaminants such as heavy metals, lead, mercury, hydrogen sulphide, aluminum, arsenic, cadmium, chromium, and barium, in addition to chlorine, fluoride, E.Coli, giardia, algae, fungus, scale, and sediment in water.
Lightweight, thin and durable, everyone should have one of these remarkable devices in their bug-out-bag, emergency kit.
How do they work?
Advanced hollow filter membrane technology is used, which requires no batteries or chemicals and has no moving parts. In some models extra layers or stages are added that may include activated carbon granules which contain IONIC SILVER known to be a potent antibacterial element, and or some other patented material. Once wet, an electrostatic charge is created that not only attracts contaminants, but also electroplates them through a process called “Electro Chemical Oxidation Reduction”.
How to select a Personal Straw Filter?
There are quite a few models and copycat designs on the market and prices vary from approximately $10 – $30 each. The main thing to be aware of is the size of the filter used, which is measured in Microns; the lower the number the better filtration. Note that none of these devices can filter dissolved chemicals.
The cheaper models offer filtration of particles no smaller than 0.2 microns and the more expensive units filter down to 0.05 microns. Protozoans like Giardia and Cryptosporidia are about 6-10 microns and 3-5 microns in size. The other factors to consider is the water flow-rate or ‘how hard you have to suck’, and re-usabilty.
