Grayl Water Filters – Sustainable Water Bottles with Integrated Water Treatment

Grayl is more than an ordinary brand for water bottles. The founders are inspired by the idea that everyone should have access to clean drinking water without harming the environment. Their mission: with the help of sustainable bottles, massively reduce the consumption of disposable plastic bottles. How does it work? Grayl's bottles are equipped with an integrated water filter and purifier that removes contaminants, bacteria and viruses from the water. So you can enjoy clean water for refreshment on your backpacking or bike tours anywhere in the world. 

But Grayl does more than that: they support non-profit organizations all over the world that work to provide clean drinking water and protect the oceans. With a drinking vessel from the brand, you not only support Grayl's mission, but also become part of the solution – to make the world a better place together. 

Innovation is a big word, especially for water bottles – so what's behind it at Grayl? Grayl's patented filtration technology works without pumping, sucking or long waiting: Simply fill the outer bottle with water, insert the inner bottle with the filter and press it down. 

One technology, two variants – the basic differences of Grayl water bottles:

• The UltraPress variant: press and purifier provide clean and safe drinking water in 15 seconds.
• The GeoPress variant: Larger bottles and even faster results. Drinking water is available in eight seconds. 

What all Grayl bottles have in common: The filter and purifier remove 99.99 percent of viruses, bacteria and protozoa that can cause cholera, hepatitis A or the rotavirus, among others. The filter also reduces contaminants such as chemicals, heavy metals and microplastics. Health protection from disease-causing pathogens and a refillable source of refreshment, the technology is the ideal companion for any long ride or when you're out and about on both feet.

If you can't find purified water on a bike ride, Grayl's bottles put clean drinking water just a few simple steps away. Whether from a creek, lake or tap – thanks to the filter you can be sure that your water is free of contaminants or pathogens. But be careful: always use fresh water for the flask and never seawater or contaminated brackish water. 

Good news for those traveling light: Grayl bottles are hardly bigger and heavier than a normal flask with the same volume, despite the range of functions – so they fit in any backpack. Thus, you can fully concentrate on the experience on every tour and enjoy clean drinking water for refreshment. 

The next bike ride takes longer and you are looking for a way to always have drinking water with you as a group? Then the Grayl GeoPress water bottle with its increased capacity and faster filter time is a real alternative. With a capacity of about 710 ml, it's slightly larger than its UltraPress counterpart, and the filter and purifier do their work in a sporty eight seconds. In addition, one GeoPress cartridge is sufficient for up to 250 liters, so you can press a maximum of 350 fillings through the filter and purifier. For a longer adventure on the weekend, e.g. with an overnight stay outdoors, you are well supplied as a small group with the Grayl GeoPress and fresh cartridge. 

You appreciate the tranquility and atmosphere that a self-supported solo tour offers? If you're a lonesome rider who sometimes forgoes company while riding, you'll want the Grayl UltraPress. The compact 500ml capacity water flasks fits in small pockets, so you'll have more room for other items on your next solo adventure. Smaller capacity also means a smaller cartridge, but with a maximum of 150 liters you can chase through the UlltraPress per filter, you'll be supplied with fresh water for a long time. 

Talking of adventure: Grayl also offers the small UltraPress bottle in an exclusive titanium version. The special feature? It's the world's first titanium filter bottle, so it offers the ideal balance of light weight and unbeatable durability. So the fireproof titanium won't let you down, even in the truest sense of the word, in tricky situations. If your path often leads you into rough terrain, where you prefer to travel undercover, you will find your travel companion in the UltraPress Purifier titanium bottle in the Covert Edition with camouflage pattern. 

If you are a full-seasoned outdoor explorer and also like to camp on a longer tour or trekking, then you will also benefit from the versatile uses of Grayl drinking vessels:

• Frost resistance: in colder climes, frost is not uncommon, but you are ideally protected from this with both the GeoPress and UltraPress. The filter cartridge can withstand up to three frost cycles without any significant loss of filter performance. Nevertheless, it is recommended to take your Grayl bottle with you into your sleeping bag, so that you have a good water supply even at temperatures below zero.
• Bike packing: If you want to make a bike tour with overnighter, you need fresh water not only for drinking. Thanks to the easy purification process, you can also use the drinking water for cooking or for your morning coffee. So you start full of energy into the next stage of your tour.
