ya why not.... you fill water of your home that will be safe to drink..a couple times. but youre not supposed to re use water bottles because something on the inside walls of the bottle will start running into the water or something. i just remember hearing something about this but i dont remember exactly the reason why youre not supposed to re use them. but you can reuse each bottle a couple of times. just make sure you rinse it out good before each use.. and only reuse each one like once or twice.
