Filter Bottle Doubles Kickstarter Goal

A startup called Liquidity Nanotech has created a water bottle filter that turns dirty water into clean, drinkable water. According to NBC Bay Area, the "Naked Filter" is also part of an effort to cut down on wasteful plastic water bottles.

The product currently has more than 1,700 backers on Kickstarter, and has raised more than $81,000 after setting a goal of $40,000.

According to the Naked Filter website, the filter removes 99.9999 percent of disease-causing bacteria, with each filter lasting 20 to 30 gallons (75 to 115 liters). Water passes through the filter while a user drinks, and doesn’t require any pumps or batteries. It operates by filtering water through a carbon core, which reduces chlorine and potential bad tastes and odors, and a a nanofiber membrane, which traps cysts, bacteria and any particle larger than 0.2 microns.

Over time, the filter's flow rate slows down, letting users know that it's time to replace the filter.

The bottles and filters are currently available for presale; with the Naked Filter bottle design still a work in progress as of March 10. The filters are available in packs of three or as a package with the bottle.
