Filter or Infuse with the bobble Plus by Bobble – you choose and features a modular cap system. With the carbon filter removed, the filter cage acts as a fruit infuser. Just add your favourite fruit or vegetables to the bottle, replace the cap, and enjoy. The wide neck of the bobble Plus allows for the fastest flow yet with your filter, big enough for ice cubes and lets you get plenty of goodness into your infusions! Replaceable carbon filter is equal to 300 single-serve 550ml water bottles. Convenient, soft-touch carry cap. Durable, squeezable bottle material. Mouth is wide enough to fit most ice cubes. Material: BPA-free Tritan™.
