I have been dealing with Osmiowater over the last week with a problem on a system that was purchased and installed several years ago. The team have an excellent knowledge of their products which they are selling and the discontinued products. Osmiowater is a company that ensures customer care and satisfaction is performed to a highest level. They have met and exceeded all the expectations that I had as one of their customers.
Incredible service, Very patient team and always trying to help!
The best customer service I have come across RENE extremely helpful Dave Liverpool
You must fit a pressure reducing valve if you connect their filters to UK mains water. This is not clear when they take your order. Mine has had parts replaced but still leaks and now i have to get the plumber back to fit a pressure reducing valve. That's £35 for the valve plus the fitting. Osmio should make this clear when they sell the product. I'd advise buying a product from a different supplier that can be connected directly to UK mains supply. And i just searched on the website for the products EZFITPRO-200 EZFITPRO-300 and EZFITPRO-400 and there is no mention of the word valve or PRV. My plumber tells me that it not unusual for the water pressure to rise to 9 bar overnight when few people are drawing water. Your reply reduces my faith further.
The service from Osmio is truly exceptional. It's rare to deal with a company that has deep knowledge of products and outstanding customer service. Mark made sure I had all the required fittings to ensure my installation went smoothly and it did! The system I'm using now is excellent, great value for money and it has made a huge impact on me and my family. I would highly recommend Osmio for anyone looking to get filtered water at home.

Osmio Water receives a mix of feedback from its customers, highlighting both positive experiences and significant concerns. Many reviewers praise the quality of Osmio's water filtration systems, particularly the Osmio Fusion, which some claim has transformed their daily lives. Customers also commend the company's service, noting quick delivery of replacement filters and helpful support from staff. However, a substantial number of critical reviews express dissatisfaction with customer service, citing issues such as delayed deliveries, faulty products, and unresponsive support when problems arise. Complaints about water quality, including unpleasant tastes and defective components, further contribute to the negative sentiment. Overall, while some consumers are satisfied with their products and service, the recurring issues indicate a need for improvement.
