Taste – Personal preference always plays a part. Some consumers want the taste of natural spring water from a bottle fed cooler. Others are happy with mains water fed through a carbon micron filter that removes the vast majority of any impurities.
Convenience – With a bottle fed cooler one has to buy, store and carry bottles of water constantly throughout the year. With a mains fed cooler the only possible additional demand/cost is cups.
Cost comparison – Most water coolers from Mirage are rented and a mains fed cooler is more expensive to rent than a bottle fed unit. The ‘cost line’ on the graph starts to move in favour of a mains fed cooler once three or more bottles of water are consumed per month.
