GRAYL Ultralight Water Purifier [+ FILTER] BOTTLE

Purify Water Anywhere!

Purification + Filtration — Safe Water for Any Adventure

The GRAYL Ultralight Purifier Bottle goes beyond standard filtration, protecting against the full-spectrum of pathogens (bacteria, protozoa and virus) as well as many chemicals, heavy metals and flavor/odor. Whether you are on the trail needing to drink from a dirty stream, filling up at a questionable hotel sink in Peru, or making your emergency preparedness kit — GRAYL has you covered.

  • Outdoor Adventures: Whether your passion takes you into the high alpine forests, fly fishing on a gentle stream or just on a hike at your nearest state park, GRAYL makes safe, clean water easy. Don’t worry about bacteria or protozoa – or nasty chemicals that may be leaking out of that abandoned mine upstream!
  • International Travel: The GRAYL Ultralight Purifier Bottle is the ultimate travel companion for travel where water isn’t safe. The Bottle fits in standard backpack side pockets and passes through airport security in your carry-on (drink the water first). 
  • Emergency Preparation: Hurricanes, tornados, earthquakes (oh my). When disaster hits, municipal water systems are the first to go down. Be prepared! 

Each GRAYL bottle comes equipped with a replaceable purifier cartridge that lasts for about 40gal (150L), enough for 2-3 months of drinking water. Replacement Cartridges can extend the life of your bottle indefinitely!

Trusted Purification Technology

GRAYL’s replaceable Purifier Cartridges keep you safe, by combining three technologies.

  • Technology #1 – Two layers of non-woven ceramic fiber, which provide a rugged and durable base.
  • Technology #2 – Positively charged mesh of ions (aka – little magnets) that grab onto impurities as they flow by, using a scientific property known as ‘ion exchange’. The positive ions in the media bind to negative charges on pathogens and chemicals. The impurities stay inside the cartridge and clean water flows through!
  • Technology #3 – Activated Carbon absorbs flavor/odor and many chemicals and heavy metals, so your water safe and tastes great.

Built for harsh environments: Purifier cartridges contain two layers of this media, to enhance impurity removal and to provide a second layer of protection during your adventures.
