Kickstarter is a great way for small startup companies to share their ideas with the world, acquire much-needed funding, and generate public interest in buying their products. We have shared several interesting Kickstarter projects in the past, such as the DPx HEST/F Urban folding knife and the Ti2 Whar-Biner EDC tool.

GRAYL claims its patented Ultralight water bottle is “the world's best”.

This time around, we spotted a water purification device that caught our eye on Kickstarter: the GRAYL Ultralight water bottle. This comes from Seattle-based company GRAYL, which was founded in 2012 by CEO Nancie Weston, as a result of concerns about disposable water bottle pollution and the poor quality and taste of water she experienced while traveling.

The Ultralight water bottle was in development at GRAYL for over four years, and the company has boldly claimed it to be “the world's best purifier” and “the only bottle anyone anywhere will ever need”. While that last part may seem a bit lofty, the bottle's specs are actually pretty impressive.

It features full-spectrum purification and filtration, meaning that it removes over 99.999% of bacteria, viruses and protozoa. It even removes particulates such as silt, chemicals such as chlorine, and heavy metals such as lead. This is substantial, as many competitive products only filter a handful of these pathogens.

At only 10.9 ounces, this water bottle also certainly lives up to the Ultralight name.

So, how does it work? Simply fill the outer shell with virtually any fresh water source, then insert the inner filter carrier, and use your body weight to press down firmly.

The patented technology forces water through the interchangeable filter cartridge in under 15 seconds, leaving you with clean, purified water. Each cartridge is good for about 300 uses, which amounts to 40 gallons of water.

Since launching the Kickstarter campaign, GRAYL has almost quadrupled their $25,000 funding goal, which is a very good sign for this new product.

The GRAYL Ultralight is currently available through the Kickstarter page for $49, and the company estimates normal retail price will be $60 once the Kickstarter ends in March. For more information on GRAYL and their other products, visit
