The Cauldryn Fyre, the future of water bottles, boils water with a battery

cauldryn fyre
Boiling water for drinking, cooking, and cleaning is a necessity in the backcountry but has traditionally required a fire, stove, or power outlet — until now. The Cauldryn Fyre innovates the outdoor experience with a battery-powered water bottle that allows you to bring water to a boil and also keeps your liquids heated all day long. 

Number 6 Brands is a company devoted to bringing the most innovative outdoor products onto the market, engineered by experts in their corresponding fields. The Cauldryn Fyre was developed in order to improve the way that people operate in the wilderness.

The company offers two different product models, the Cauldryn Fyre and the Cauldron Fyre Mobile, both of which are capable of holding 16 ounces of fluid. The product is a modular design that includes a stainless steel vacuum insulated bottle with a lid and the original Fyre heating element. The difference? The Cauldryn Fyre Mobile features a rechargeable battery.

The Fyre heating element is a revolutionary high-capacity rechargeable battery that attaches to the bottle. It can deliver two boils from a single charge and has four different heat settings including hot, extra hot, brew, and boil, serving for a ton of different options. Whether you want to warm soup for eating, boil water for cooking, steep a cup of tea, or brew a cup of joe, the Cauldryn Fyre heating system is designed to meet your every need.

The Fyre heating element allows for contents to reach up to 212 degrees — hot enough to kill contaminants and provide for clean drinking water. The Fyre can also run directly from either an AC or DC power source, adding to the product’s adaptability. This feature allows for the Cauldryn to use the included AC base or optional DC base to produce an unlimited boil, brew, high heat, or drink cycles. 

Getting caught in unpredictable conditions is a certain possibility when you venture into the wilderness. Whether you’re on a backpacking expedition, climbing a mountain, or going on a day hike, the ability to boil water is a necessity. Now you can leave your heavy stoves and fuel at home and boil water with the push of a button.

The Cauldryn will soon be live on Kickstarter before its debut at the Outdoor Retailer trade show in late July.

Purisoo lets you purify water via its innovative pumping system
purisoo water bottle

Rather than bringing liter upon liter of bottled water with you on your next nature adventure, you may instead be able to depend upon the water found in nature itself. No, you won't have to bring iodine capsules, and no, you won't just have to drink straight from the stream. Rather, with the new Purisoo bottle, you'll have a reusable, portable, water purification system that you can use just about anywhere at anytime. Whether you're hiking, traveling, or facing a clean water shortage at home, the Purisoo hopes to help by giving you a way to manually pump any fresh water source into clean, safe, drinking water.

The Purisoo hopes to serve as your emergency resource when it comes to attaining filtered, potable drinking water. Capable of processing up to one thousand liters of water (or about two thousand bottles of water), the Purisoo's replaceable filters capture and eliminate impurities from fresh water sources. You can collect water from a river, a lake, or even the tap at a campground, and begin pumping away the potential contaminants.

The Astrea water bottle will filter the lead out of your H2O

Filtering your water may soon be as easy as drinking it from a special bottle. HaloSource, a global clean water technology company, is taking to Indiegogo in order to launch its first consumer product. Meet the new Astrea bottle, the flagship offering from HaloSource's new U.S.-centric brand Astrea. The water bottle claims to be the world's "most effective daily-use filtering water bottle," and claims to remove lead to the highest National Sanitation Foundation standard -- NSF 53.

On Thursday, March 22, the Astrea bottle launched on Indiegogo, and managed to raise more than half of its $50,000 goal in a single day. The Astrea bottle is meant to address the rather alarming presence of lead in the U.S. water system. In November 2017, Reuters found 3,810 neighborhoods throughout the U.S. with recorded childhood lead poisoning rates that were double those found in Flint, Michigan, during the height of that city's contamination scandal. But Astrea hopes to help individuals and families take the quality of their water into their own hands (or rather, into their own bottles).
