In this video I examine the effectiveness of water treatment methods such as filtering and boiling. I put 3 samples into the water analysis and you can find out the results. I use the Grayl Ultrapress water filter (self-paid, therefore unpaid advertising) for one sample, a pure water sample in a contaminated region and a boiled version for the analysis. Together we compare parameters such as color, turbidity, pH value, bacterial counts and more - find out in this video which method is best suited for water treatment.
