These filters are great at filtering city water which is what I use it for the most. Definitely a repurchase even though they are a little pricey. Great investment into health though.
I love knowing that I am drinking clean water by using my bottle filter! It is so convenient to have clean water easily accessible at home, work or when I'm out on an adventure. It did take me a little bit of time to adjust to the resistance of sucking water through a filter, but I love my filter and am sure that you will too!
Recently purchased Nalgene Bottle with built in filter. Excellent product and superior service!
On my second filter and still just as amazing as when I first bought it.
Great product can't recommend enough I really enjoy how many plastic bottles it replaces
