We all know what happens when we decide to grab a water bottle from the street. Unless you have the iron stomach to digest roadside pani-puris in India, you are one of the millions who might fall prey to diarrhea, or worse, dysentery because of their brave attempt. To fill in that large chunk left vacant by hypochondriacs who dread stomach problems all over India but love to travel, here’s a solution. Astrea Mobi-Pure bottle aqua is a bottle that features disposable cartridges that offer three-stage purification, using water purification technology to kill more than 99.9 percent of viruses and bacteria, including E. coli and Norovirus. Each cartridge can be used to provide for 375 liters of drinking water and replaced. So, plan your next backpacking adventure and don’t forget to bring along the Astrea. Priced at ₹1099 on Amazon, it’s a small price to pay for your health and peace of mind.
