What do I gain by buying an Ecolife metal bottle? You gain health, well-being & continuous hydration! Having an Ecolife metal bottle always with you, you can quench your thirst in an instant, easily & quickly. In addition, you save money, since you don't need to buy bottled water all the time & you relieve the environment from the hundreds of plastic bottles you would consume. And the most important....! You do not burden your body with the chemical & carcinogenic substances of plastic, as stainless metal is the most suitable material for drinks & food. 2) Why not reuse the empty plastic bottle from the bottled water? I wash it often & don't leave it in the sun. Because no matter how 'meticulous' you are, your empty plastic bottle will not become less dangerous for your health. Remember bottled water bottles are for single use only! The carcinogenic substance Bisphenol A (BPA) found in plastic bottles can very easily leach into water after repeated reuse. Even worse if the bottle is exposed to high temperatures, such as in the car or the beach. Specifically, BPA has been associated with: • forms of cancer • heart diseases • hypogenetic • hormonal disorders (it 'mimics' the action of estrogen) • developmental problems of the fetus. Therefore, throw away your empty plastic bottle today! Replace it with a stainless Ecolife bottle, gain health & protect the environment. 3) I know that the Ecolife stainless steel bottle is 100% suitable for beverages & has all the necessary quality certificates. Does the same apply to its plastic caps? Of course, because they have passed the strictest checks! Together with the stainless steel, they were sent to the laboratory for quality testing. The test showed that they do not contain the harmful substance Bisphenol (BPA free) & are 100% suitable for reuse. They have FDA & SGS certificates, just like the stainless steel bottle.
