Does a Great Job and Easy to Replace

I monitor my filtered water for total dissolved solids, and the RKIN RO membrane gets the job done on total dissolved solids. The membrane is easy to change. All I needed was a screwdriver, the RKIN instructional video on YouTube, and about ten minutes. I have used my RKIN system for four years, and I recommend RKIN to my friends when they have an interest in RO filters. The customer service is excellent, too!



Hi Sam! Thanks for sharing your RKIN water systems experience! We're thrilled our RO membrane effectively reduced total dissolved solids in your water. It's great to know changing the membrane was easy for you. Our YouTube videos aim to simplify maintenance, and we're glad they helped. Your loyalty and recommendations mean a lot. We're honored you trust RKIN and share our systems with friends. We prioritize excellent customer service, so we're happy you've had positive interactions with our team. Reach out anytime with questions or concerns. Thanks for choosing RKIN! We're excited to continue serving you and your friends for years to come!
