Great bottle!

Really great bottle for on-the-go. Fits in my bag and is easy to use the filter component.

Love it!

I really love this drink bottle! I wanted to find a filter bottle that was ethical and gorgeous and this ticks all the boxes. The only down side is the plunge feature that means you can't easily refill and go, you have to take the time to carefully plunge which when I'm in a rush can be annoying. However that is such a first world problem it's not even really a problem.

Great product

Really like this bottle. I definitely notice the difference in taste of water from the tap when using this. Very happy with it :)

Best water bottle

This is by far the best water bottle I own. The filter system is genius and the water tastes incredible. The mouth piece is perfect for guzzling and the 500ml measurement helps my OCD keep track of the water I've consumed. Good plastic, easy to wash in the dishwasher and affordable filters. I highly recommend.

Eye catching and functional

I had some issues with leaking lid, but managed to work through it after being put into contact with 321 Water by F&F. This filter water bottle definitely works to clean water of unpleasant tastes, and looks great. I always get positive comments about how it looks. The white does scuff and hold a little dirt stain, and the plastic scratches a little though, but I suppose that's normal wear and tear as I put my bottle on the side of my backpack (maybe not a good idea). It might be worth considering getting the black one if concerned about longevity.
