Grayl | water purification + Filtration

Purify. Water. Anywhere

World's best purifier + Filter Bottle

ESTABLISHED 2013 - FOUNDER: Nancie Weston & Travis Merrigan - EMPLOYEES 4 - Location Seattle WA

Grayl has spent four years obsessing over every detail of the design and performance of the new Ultralight bottle — its third iteration of a water-purifying system. At 10.9 oz, the Ultralight uses Grayl’s French press-style system of pushing water from almost any source through its replaceable purifier cartridge. Clean, better-tasting water is available in just 15 seconds, in what Grayl says “may very well be the only water bottle that anyone, anywhere, will ever need.

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 Grayl's 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.
