Efficient Up-Flow Regeneration Technology

  • Minimises water and salt usage, saving money and reducing environmental impact. Unlike traditional down-flow regeneration, this system optimises the cleaning process, ensuring that only the necessary amount of salt and water is used. This means lower operating costs, reduced waste, and a more eco-friendly approach to water softening.
  • Improves resin efficiency by directing the cleaning solution upward for a more thorough clean. By forcing the brine solution to flow upwards through the resin bed, this method removes trapped minerals more effectively. This ensures that every resin bead is fully utilised, leading to a more consistent and powerful softening performance over time.
  • Extends system lifespan, ensuring long-term reliable performance. With a more even and efficient resin bed cleaning process, the system experiences less strain and wear over time. This reduces the frequency of maintenance, extends the softener’s overall lifespan, and ensures peak efficiency for years to come.

Automatic Salt Reminders & Holiday Mode

Salt reminder notification alerts you when it's time to add salt.

  • Forget about manually checking salt levels—this smart system monitors usage and sends a timely reminder when it's time for a refill. This ensures continuous soft water without the risk of running out of salt unexpectedly.

Holiday mode allows you to pause the system when not in use.

  • Going on holiday? The vacation mode feature prevents unnecessary water softening cycles when the system is not in use. This helps save water, salt, and energy, preventing waste while ensuring the system resumes normal operation as soon as you're back.

Installation and Maintenance

The Osmio CS Digital Water Softener is compact yet powerful, designed to fit seamlessly into your home setup.

 (DxWxH mm): 497 x 300 x 1055

Is the 30L capacity suitable for my household size?

It's ideal for homes with 4 to 6+ people or 2 to 4 bathrooms, offering extra capacity to handle higher water usage without frequent regeneration. If your household has multiple occupants or you regularly use several bathrooms at once, the 30L size provides efficient, reliable softening with plenty of headroom.

How does the Up-Flow Regeneration Technology benefit me?

The Up-Flow Regeneration Technology in the Osmio Digital Water Softener improves efficiency by using less water and salt, reducing running costs and waste. It ensures better resin cleaning by directing the brine solution upward, preventing clumping and maintaining consistent performance. This technology also extends the lifespan of the system, making it a cost-effective and eco-friendly solution for long-term water softening.

What are the installation requirements and dimensions of the unit?

Product Size (DxWxH mm): 497 x 300 x 1055mm / Plumbing Connections: 3/4” or 1” fittings available / Power Supply: 110V-120V / 220-240V AC, Output 12V AC 650mA

What maintenance is required, and are there any ongoing costs?

The 30L Osmio Digital Water Softener requires minimal maintenance. The main ongoing cost is salt, and the system includes smart salt reminder alerts so you’ll always know when it’s time to top up—no manual checks needed. It also features a vacation mode to pause operation when you’re away, helping save salt, water, and energy.

Experience the transformative benefits of this home water softener as it effectively eliminates limescale build-up on faucets, showerheads, and appliances. Enjoy softer skin and shinier hair, as softened water enhances the effectiveness of your personal care products. Your laundry will feel softer and look brighter, and your dishes will emerge spotless and gleaming.

Over 60% of homes in the UK have hard water, around 16m homes. Obvious signs, such as frequent equipment failures, noisy boilers, diminished water pressure, and the accumulation of chalky, crusty deposits, point to the presence of hard water. Only a water softener can eliminate this issue, and it will also clean your pipes of chalky deposits that have built up over time. If left untreated, you may see signs such as reduced water pressure, damage to household appliances, leaking and burst pipes, poor water quality, reduction in your clothes quality, and increased energy costs. Additionally, you will almost certainly face the burden of extra cleaning to remove the unpleasant chalky deposits.

The damage caused by limescale can be both frightening and expensive. Why wait for it to happen?
