How does it work?

The LARQ Bottle Filtered Flip Top is a portable water filtration system that combines a high-performance Nano Zero filter technology with a seamless, low-pressure drinking experience. As you sip through the straw, our Nano Zero filter removes a range of contaminants like PFOA/PFOS, chlorine, pharmaceuticals, and more. (Filters are tested to NSF/ANSI 42, 53 & 401 standards). 1 LARQ Essential Bottle Filter replaces 189 single-use water bottles!
