Reviews

Safer than not filtering and reduces bottled water.

"Safer than not filtering and reduces buying bottled water. I haven’t tested all that it filters. I have used it sometimes at work when the water tastes funny, during boil water notices, and when hiking/backpacking. I do question on the purification part. I tested the water post filter with a TDS tester and the result is the same as tap water pre-filter. Not sure if that should be the case. I would still use and recommend the product with questionable waters. Especially if traveling in other countries."

Water taste better

"After researching many water filter and purifier methods, I find this filter to be the best for taking out viruses, bacteria, micro plastics, and helps to improve water taste. After getting sick in Mexico by drinking the water, I now take a Grayl with me wherever I go."
