[su_box title=”Personal Filter Straw Review”] The Personal Filter Straw uses a filter as well as chemical elements to purify water. The filter size is not mentioned, which suggests that the chemical element, iodized resin, is what is used to kill protozoa, bacteria and viruses. It can filter up to 750 liters of water before needing to be replaced. As is the case with the other outdoor water purifiers, the flow rate will vary depending on use. The manufacturer website was hard to find, but Blue Water Markets seems to be the company selling these. There is no mention of the filter size and it seems that it is relying on the iodized resin to kill the bacteria, protozoa and viruses. This has the shortest life span of our five outdoor water filters, only filtering 750 liters.
