Someone think Glass bottle is the healthiest water bottle to use, someone think plastic water bottle is the healthiest water bottle to use, Actually, you can get what you pay for , so we’d better not to stick on the material. If you want to get the healthiest water bottle, when you buy a bottle, you need to check the necessary certificates and confirm their certificates are trust worth ! getting the certificates number to confirm on their official website. For example, FDA certificated, It is a USA standard, you need to get the certificates number and check on a US FDA official website, but not on other unknown website. If you can find the trusted information on website, that means you can buy the bottle and do not mind the brand and materials !
