Water bottle? Filtered water? Why not both?
I had heard about Bobble bottles before, so I was excited to see them sold at Crate & Barrel. The idea of this bottle is pretty neat- the cap is attached to a small water filter, so you can fill up the bottle with regular tap water. Once you fill and empty the water once or twice (you'll notice the water is a little discolored from the filter's charcoal), just keep refilling and drinking!
One weird thing is the hissing air that happens every time I try to take more than a few sips- it literally sounds like the bottle is sighing at me, haha. From a few reviews, it seems like the elongated filter might be the cause of that. But clearly it's not a deal breaker for me. Overall though, I like having this on hand, especially for trips away from home. Having it around is also a good reminder to drink water throughout the day!
