Product Description
5-Stage Water Purification
The Infinity RO combines five stages of advanced filtration into one compact, all-in-one system. The pre-filter (replaced every 12 months) and RO membrane (replaced every 36 months) work together to remove chlorine, limescale, lead, pesticides, parasites, cysts and other contaminants — delivering nothing but pure, great-tasting water.
Smart Tap Technology
The integrated LED ring on the smart tap provides clear visual feedback on your filter status. Blue indicates more than 150 litres or 15 days remaining, purple warns that the cartridge is nearly exhausted, and red signals it must be replaced. No guesswork, no missed changes.
Effortless Maintenance
Cartridge replacement couldn’t be simpler with the twist-and-lock system. Just three steps: remove the front cover, rotate and remove the old cartridge, then insert and rotate the new one. The system also features quality control, flushing ready indicators, and audio warnings for complete peace of mind.
Better for You & the Environment
Enjoy delicious water on demand from only 2p a litre — more cost-effective than a filter jug. Eliminate single-use plastic bottles (which can take up to 450 years to biodegrade) and enjoy the real flavours of your food, free from chlorine and other contaminants.

What Our Customers Say
“We recently had Southern Softwater visit our home to walk us through the available options, and the experience from start to finish was excellent.The initial consultation was clear, informative, and pressure-free. They took the time to understand our needs, explained the different systems in a straightforward way, and answered all of our questions patiently. It felt like they genuinely wanted to help us make the right decision rather than just make a sale.The installation process was just as impressive. The installer arrived on time, was extremely professional, and worked efficiently while keeping everything tidy. He explained how the system works, made sure everything was set up perfectly, and left the area clean once the job was complete.Overall, we’re delighted with both the service and the product. It’s rare to find a company that delivers such a smooth and professional experience from consultation through to installation. Highly recommended.”
“I have dealt with Southern Softflow for 22 years. Recently after 22 years a fault developed on the machine. The machine was taken away and repaired at a very reasonable cost. As I had moved house I had the machine installed by the kitchen company installing the kitchen and they made a poor job of the pipework needed. When Will from Southern Softflow brought the repaired machine back he rerouted the pipework and put new valves in and did a very neat and professional job. I am delighted. A very genuine and professional company ,a delight to deal with.”
“We've had fantastic service from Southern Softflow from initial enquiry through to installation and beyond. This is our first water softener (TwinTec S5) and we can't fault it (we wish we'd installed one years ago). Southern Softflow's friendly and accommodating service is what set them apart from other companies that quoted. There was no pressure to place an order, and they were very accommodating, as this softener was purchased during a renovation of the whole downstairs, including new kitchen, bathroom & plumbing throughout, so they had to coordinate with our plumber and fit in around other trades. Competitively priced. Fantastic product. Excellent service. I highly recommend Southern Softflow.”
“Moving home to an area with very hard water, I decided it was time to install a water softener. After research, I chose Southern Softflow, who offered exactly the reassurance and expertise I was seeking. Decision to installation took two days. Installation itself took a little over two hours, was carried out neatly, efficiently, and professionally. The new tri-flow drinking tap looks great in the kitchen, and even though I’ve used Brita filters for years, tea already tastes noticeably better after only 12 hours. Many thanks to Ben, Will, and the team, greatly appreciated. A full 10 out of 10.”
“Southern Softflow’s response to my call for help was amazing, from Edith in the office, Keith the boss man to Will the plumber who worked so hard and did a first class job. A truly great personal service not found easily these days. My heartfelt thanks to them all !”
“Brilliant service. Survey done clear explanation of product from Ben. Fitting done three days later. Very helpful and tidy technician. Added a hard water tap at the last minute no problem. Would highly recommend the service and product. Thanks guys!”
