Lack of access to clean water is not fun. The LUMISTRAW is a water purifying straw you can use anywhere get around that. It has a silicone straw tip and uses a high powered UV-C LED light to get the job done. One charge can purify 45 cups of water. No need to deal with filters either.
LUMISTRAW purifies as you drink. It eliminates viruses and bacteria and lets you pick your own container.
