We have been using the services of The Water Filtermen for some years now. We originally brought and fitted our five stage reverse osmosis system from The Water Filtermen. With easy instruction and instalment, we have stayed loyal to the source of our product, consistency of service has always been a important factor for our choice. We are happy with the affordability and simplicity of purchase and renewal of the filters. As I have said we have had excellent service from The Water Filtermen for many years, and would recommend to anyone considering to purchase. I am a happy loyal and very satisfied customer.
