Always have a source of clean drinking water on the go with portable water filters. Even when you are deep in the forest hiking or camping you can have access to fresh clean water with portable water purifiers. With portable water filters, you can turn murky, questionable water into clean drinking water. Our water filter straws allow you to drink directly from the source, just place your water filter straw in the pond or river, and the device will clean the water with each sip. Now you can turn ponds, streams, lakes, rivers, and even puddles that would normally make you sick, into sources of clean drinking water.
