Before the Aquablu Refill was introduced, people drank water straight from the tap. That meant certain problems where involved. The water from the tap was too warm, especially during summer or around the pool, leaving people dehydrated and sometimes overheated. This led to people drinking unhealthy but cooled sodas. This was both a problem in terms of health and in plastic bottles and cans being used.
