I needed to buy a filter but I had no clue which one to order so I contacted FreshwaterSystems and asked their rep for help. We discussed everything and their rep offered me to buy a set of filters. When my order arrived filters did not fit! I contacted FreshwaterSystems and told them that something terrible happened and that filters which were recommended to me by one of their reps did not fit. Lady on the phone said that they need time to find out what happened and asked me to contact them back later. When I did they did not even apologize! They refused to refund my money or send me the correct set! That was the worst experience in my life! I am very disappointed and will not buy from them again!
