321 Water bottle is a re-usable water bottle with a novel filtering mechanism.

Australian company Half A Teaspoon has created a sleekly designed, re-usable water bottle that has a built-in self filtering setup. After the 321 Water bottle is filled with water, the plunger mechanism which contains a carbon block filter needs to be inserted into the bottle and pushed all the way down to instantly remove chlorine and unpleasant tastes and odors to give clean, filtered water. The 321 Water Bottle can be pre-ordered for $44.60; however, the company needs 10,000 pre-orders to commence production and deliver the bottles by June.
