United StatesThis product does a great job. I called customer service twice regarding ordering replacement filters and how to change them. Excellent customer service both times. They answer the phone right away and don’t put you on hold. I recommend the Alcapure!
United StatesGREAT Customer Service
United StatesYves F was a great help in getting my filter replaced, I greatly appreciate the help.
United StatesYves F, Helped me a lot regarding the Post filters, I was facing a problem with the TDS level, she sent me new post-filters free of cost that has to install in the machine. RKIN customer support is the best Thanks Yves. F
United StatesYves was very helpful today. I experienced a premature expiration of my 4th stage filter on a new ZIP system. He was quick to troubleshoot, provide different options, and ultimately sent a complementary 4th stage filter. I am new to Rkin, but their product seems well-made, and their support is phenomenal (thanks Yves), and I expect to be a long term customer.
