Bring not only your own bottle but your own antibacterial unit. That&rsquos the thought behind Eureka Forbes&rsquo newest product for India, the first of its kind. This soft-squeeze BPA-free plastic bottle will save you buying and chucking numerous bottles of drinking water, thanks to an integrated chemical-free nano technology filtration unit whose cartridge lasts for 600 fills and slows down the flow to warn you when it is nearly time to recharge. The personal purifier even reduces chlorine levels, should you in desperation dip into a public swimming pool to quench your thirst. Though the see through panel should prevent such dire straits.
