Intelishake H20 Infuse - Multi-Compartment 550ml Water, Protein Shaker, Fruit Infusion and Juice Bottle with Carbon Filter BPA Free for Outdoor, Sports, Gym, Exercise Meet the Intelishake H20 INFUSE, a patented Multi Compartment outdoor, sports, gym, exercise, protein, smoothie, fruit infusion & juice shaker bottle. Comes with a replaceable carbon filter! You can remove the black carbon filter leaving its holder in place to use the bottle as a fruit infuser, by dropping your favourite fruits into the main water compartment. It has an activated carbon filter which has a slight electro-positive charge, making it attractive to chemicals and impurities. As the water passes through the positively charged carbon surface area, the negatively charged ions of the contaminants are drawn to the surface of the carbon surface, reducing the amount of contaminant's you drink in normal water. High quality excellent sports industry standard bottles. The bottle floats on water due to its design and handy for use as a water proof floating bottle when on the beach or swimming pool. It is a multi-compartment drinking & storage device which combines function with fashion to create the perfect work out bottle. Importantly, Intelishake allows you to carry out outdoor or exercise activities whilst storing everything you normally carry in one bottle, keeping safe your phone, cards, keys, money and storing powders or capsules you may take during work out. The carbon filters require very little maintenance, and are perhaps the most powerful chemical absorbent known to man. The carbon-based filter primarily helps with chlorine, taste and odour reduction. For best results we recommend changing your filter after 2 months or 45 gallons/160 litres. Do not use to filter water which is from micro-biologically unsafe areas or of unknown quality like rivers and streams. It is commonly used to filter drinkable tap water.
