For our massage business I need a water purifier.  Besides quality of filtration, I also am interested in the best - natural - look of the filter (the visible stones etc.) because I would like to use the filter in massage establishment. I like most the Mineral Water Dispenser KS-971, however, does it also cool do water, or is it room temperature?  If it is room temperature, can it be designed also as a cooler? For your Hot & Cold Top Water Purifying System ( KS-966P ), I really need only cold water, do you have any products like that?
Also, could you please specify for me the cost, cost of shipping (to Honolulu, Hawaii 96826, USA), and what kind of care do the individual purifiers need, what is the cost of replacement filters, or how they need to be treated etc.
Thank you for all the information.
