ÖKO - Advanced Water Bottle with Filter Derived from NASA Technology, Filtered Water Bottle for Travel/Outdoors & Home, Water Filter Bottle for Harmful Contaminants (650 ML, Moss)

I am a long term Hydro Flask user and was having a hard time deciding on what filter to get to use with it on my travels. I gave up after reading reviews saying how hard it was to get water out using that system. I figured I'd give this bottle a go and on my last trip I put it to the test. It is pretty easy to drink from and to squeeze water out into another container when needed. How much of the yuckies does it get rid of? Well it's not a reverse osmosis system, so just enough. I wouldn't put water from a mud puddle to test it's filtration as it would clog the filter, but from the company's website I was confident enough in it to make the water better where I was going.
