The LARQ Filtered Straw is a portable water filter that drops into a bottle so you can drink filtered water through a straw. Its Nano Zero filter is plant-based and certified to NSF/ANSI 42, 53 and 401, which means it reduces chlorine, PFAS such as PFOA and PFOS, and pharmaceuticals. It fits most bottles through two included adapters and comes with four straws. Against pitcher filters it is far more portable and filters as you sip; against built-in filter bottles it is cheaper to try and works with bottles you already own, but the filter is small and needs replacing roughly every two months.

Owners like the taste improvement and the convenience of filtering while they sip, and they value the third-party NSF certifications. The main complaints are the short filter life and the cost of frequent replacements.
The LARQ Filtered Straw is a portable water filtration system that pairs a Nano Zero filter with a low-pressure drinking experience. The filter is plant-based. It also works as an Essential Bottle Filter, improving the taste of water for a smooth finish.
The filter removes chlorine, PFAS (PFOA/PFOS) and pharmaceuticals, to NSF/ANSI 42, 53 and 401 standards. One filter lasts up to 2 months or about 25 gallons (94 liters), which equals about 189 single-use bottles.
Before first use, rinse the filter under running water for 30 seconds and make sure it is soaked.
