Replacement Travel Purifier

Replacement purifier for the Grayl Water Filtration Press.


Seattle-based Grayl is on a mission to change the way the world purifies and drinks water with the revolutionary Water Filtration Cup, a 16 oz travel cup that uses a French Press system to filter water. Just fill, press an inner cup into the outer drinking cup and in 15 seconds you’ve got safe, portable drinking water, 99.99% free of yucky stuff like bacteria, protozoa, arsenic, lead, BPA and pesticides. There’s no waiting, pumping, squeezing or disposable plastic bottles involved.

The founder of Grayl, Nancie Weston was so determined to create a beautifully designed all-in-one filtration/drinking cup, that even after being told by twelve engineers her idea would not work, she mortgaged her home and started the business.

The cup is made of food grade silicone and durable,18/8 stainless steel. The advanced G3+ filtration technology combines fast flow with an unrivaled ability to grab microscopic particulates. Each refillable cartridge is good for up to 300 filtered drinks. and keeps you safely hydrated about town or on international travels. more Their Story
