Verified Purchase(What is this?)
This review is from: WATER PURIFICATION FILTER BOTTLE - REMOVES CONTAMINANTS BY 99.9% - DEVELOPED BY THE AMERICAN SPACE PROGRAM "NASA TECHNOLOGY" (Misc.)
Best piece of travelling kit. Allows me to drink tap water (I've been on the road in Thailand for two weeks now and haven't been sick) thereby saving money, lugging large bottles of water around and contributing to plastic bottle waste. Better than the water straw we also bought. A water bottle is just more convenient. It's roughly 750ml and the filter is surprisingly light and doesn't add that much weight to the water bottle.
