GRAYL Ultralight – World's Best Purifier [+Filter] Bottle

Purify water. Anywhere. After four years of obsessing over every detail of its design and performance, we're excited to unveil the GRAYL® Ultralight Purifier Bottle. Fast and easy to use; it makes clean, purified drinking water (in less than 15 seconds) from virtually any fresh water source in the world! It's a game changer and may very well be the only water bottle that anyone, anywhere, will ever need. 

Full-spectrum purification (+filtration). Ever spent three days attached to a ceramic throne due to bad water? With [ONE PRESS], the Ultralight offers the ultimate protection against pathogens (viruses, bacteria, protozoa), particulates, chemicals and heavy metals.

Removes 99.9999% of viruses (e.g. Rotavirus, Hepatitis A), 99.9999% of bacteria (e.g. E coli, Salmonella), and 99.999% of protozoan cysts (e.g. Giardia, Cryptosporidium).

For global travel, outdoor adventure and emergencies. Whether you’re filling up at a questionable hotel sink in Peru, on a gnarly trail needing to drink from a dirty stream, or at home prepping a disaster kit —the Ultralight Purifier has you covered.

Safe water for any adventure. Designed for minimalists seeking the ultimate in convenience, portability and performance; the Ultralight is a perfect compadre for walking the globe, traversing a trail, adventure travel, or whitewater descents — anywhere!

Sustainable travel. Single-use plastic water bottle consumption is proliferating at a staggering rate and global plastic pollution is now an epidemic. This is especially evident in destinations where tap water is unsafe to drink, which often correlates to an increase in plastic pollution in streams, estuaries and empty lots. Travelers can now avoid buying bottled water altogether, and instead use the Ultralight Purifier Bottle for treating all their water. Up until now, there has never been a more efficient and convenient means to purify (+filter) water on-the-go.

The lifespan of GRAYL's Replaceable Purifier Cartridges is 300 uses (40 gal/150 L).

ELECTROADSORPTIVE PURIFICATION [+FILTRATION] MEDIA

Unlike standard mechanical filtration, the Ultralight is powered by a patented game-changing electroadsorptive media capable of removing submicron pathogens and inorganic contaminants. 

With [ONE PRESS], electroadhesion and ion exchange create a powerful submicron trap for pathogens (viruses, bacteria and protozoan cysts). Additionally, the purifier media contains many embedded layers of ultra-powdered activated carbon which create a large surface area for removing toxins like chemicals and heavy metals.  Silver treated zeolites, a natural antimicrobial, inhibit growth and keeps the purifier fresh between uses.

THE GRAYL STORY

Water has shaped our landscapes and every civilization. Today, far too many people do not have access to safe drinking water, and those of us that do rarely have truly clean drinking water. Sadly, serious contaminants such as fracking chemicals, pharmaceuticals and even E. coli contamination are turning up in our "potable" water.

Here at GRAYL's offices in rainy Seattle, our comparatively clean and abundant water still contains added chlorine, trace amounts of arsenic and lead. We have dared to imagine that it should be possible to avoid both immediate and cumulative water hazards globally. We've now made that simple to achieve with [ONE PRESS] purification (+filtration).

The Water Filtration Cup, our first product, was released a couple years ago. It received a lot of media attention, won several awards, and rapidly attracted a loyal customer base. Much was learned over the first six months, especially around manufacturing, product design and user feedback. 

The experience of starting a company and creating a disruptive product technology has been wild and extremely rewarding, yet at the same time humbling. Some of our earliest supporters came to us with product design suggestions for improving their experience. In particular, we received requests for a lightweight and compact "bottle" capable of purification (+filtration), along with a no frills hassle-free loop cap.

The Ultralight Purifier (+Filter) Bottle represents a pure distillation of all we’ve learned over the last few years and since have aspired to create. 

About Our Co-Founders:

Founded in 2012, GRAYL was inspired by two global travelers, Nancie Weston and Travis Merrigan, and their concerns about global plastic pollution and the poor quality (health, taste, odor, clarity) of water that people around the world endure daily. Nancie and Travis are committed to changing the status quo by making practical and durable filtration and purification solutions. 

Nancie founded GRAYL to make a difference in the world, and to solve real world problems. Her journey began in the Cascade Mountains, infected with giardia by drinking from a beautiful crystal clear spring. Moreover, what haunted her was a beach she had visited in Mexico that was literally covered in plastic trash. She decided to make a difference by creating a product that would address both problems. 

A gifted designer with two previous patents, Nancie used her talent to imagine the system that would become [One Press]. Her tentative filtration solution, using a variation of a French press filtration method captured her imagination. Nancie consulted engineers who doubted that her idea could be done. However, she would not give up, there had to be a way. Working with a talented team, she improved upon the design, launching GRAYL’s first product, The Water Filtration Cup, in 2013. The Ultralight is a response to customer suggestions and a continual striving for improvement. 

There have been many challenges along the way, but the Ultralight represents the essence of Nancie’s original idea, and GRAYL is elated to bring it to the world.

Risks and challenges

The commitment to deliver what we promise is something we at GRAYL take very seriously. In two years of doing business, we've learned many invaluable lessons and we're confident we'll overcome challenges and risks and deliver the Ultralight Purifier Bottle to our backers on time.

Product Quality
With the Ultralight Purifier Bottle, we've made the most advanced portable purifier [+filter] bottle in the world. Our design and engineering team obsessed over the development of the Ultralight since our first product launched in October 2013. They worked painstakingly hard to deliver on very stringent design and performance specifications while utilizing only the highest quality materials. The resulting bottle (and purifier) is of impeccable quality. The Replaceable Purifier Cartridge has not changed, but has undergone dozens of tests at independent laboratories. The Ultralight contains some of the world's most advanced purification technology and will keep you safe, anywhere in the world.

Manufacturing
We have three years experience working with our manufacturing partners and they are as committed as we are to delivering the perfect product. Our design team made dozens of design changes, multiple rounds of 3D printing and tooling changes. In October and November 2015, we put pre-production samples through rigorous testing and approved the final design in December 2015. Product performance tests were so good, we decided to move our production timeline up by many months for Spring 2016 delivery.

Logistics & Timing
We work with consummate logistics professionals with decades of experience delivering product. Barring a natural disaster, we’ll deliver on time.

Warranty
Every Ultralight will be accompanied by our ten-year warranty covering workmanship and materials.
