The Single One Stop Plus™ 10″ x 2.5″ Scale Reduction Water Filter System combines a premium Global Water Solutions 10″ filter housing (H05V-6B-WW-WM) with a One Stop Plus™ cartridge. A complete, ready-to-plumb-in system designed to reduce limescale and heavy metals at a single point of use.
This kit comes with a single 10″ housing with 3/4″ ports plus a 10″ One Stop Plus Filter. Fittings are available to connect this unit to braided lines or plastic high pressure tubing.
With a maximum flow rate 4 LPM, this unit is suited to coffee machines, food service equipment, and drinking water taps.
Please note: This filter is designed for limescale and heavy metal reduction. It will not remove bad taste/odour, chemicals or sediment. Additional filters will be required of those contaminants need to be reduce.
What One Stop Plus™ Does
Limescale forms when dissolved calcium in your water settles onto hot surfaces and hardens over time — inside kettles, hot water systems, coffee machines and anywhere water heats up or sits still.
One Stop Plus™ tackles limescale using a different approach to a conventional water softener.
Rather than stripping calcium out of the water with salt and resin, it prompts dissolved calcium carbonate into forming microscopic, free-floating crystals as the water passes through the cartridge. Those crystals are too small and too well-formed to bond to pipework or appliance surfaces, so they simply carry on through the system with the water rather than settling out as scale.
The same media also reduces a range of heavy metals, including copper, lead, zinc and cadmium by adsorption.
Because there’s no salt regeneration cycle involved, there’s no brine discharge and no risk of salty-tasting water at the tap. It also means no power supply is needed and nothing needs to be added to the water to make it work — a straightforward inline cartridge that sits ahead of the appliance it’s protecting.
Where It’s Used
Fitted as a point-of-use cartridge directly upstream of a single appliance — coffee machines, hot water systems, dishwashers and spas/hot tubs are the most common applications. It can be used on any water consuming appliance with a maximum flow rate of less than 4 litres per minute.
The 10″ One Stop Plus™ filter is designed to protect one piece of equipment specifically, rather than treating the entire household supply.
Key Features
- Scale control without chemicals, power or salt. The crystallisation process runs entirely off the water flowing through it — no electricity, no added chemicals, no brine.
- Reduces heavy metals as well as scale. Copper, lead, zinc and cadmium are adsorbed by the media alongside the scale-prevention effect.
- Keeps the minerals in your water. Traditional ion-exchange softeners strip calcium and magnesium out along with the hardness — One Stop Plus™ leaves those minerals in place, so the water it produces isn’t demineralised.
- Works on scale that’s already there. Once installed, the cartridge continues drawing free calcium carbonate out of solution, which gradually loosens and clears existing scale deposits in pipework and appliances rather than just preventing new buildup.
- Extends appliance life and efficiency. Less scale build-up on heating elements and internal components means appliances run closer to their rated efficiency and last longer — relevant for coffee machines, hot drink machines, water heaters, boilers, washing machines and heating systems.
- Long service life. Cartridge life is governed by heavy metal load rather than water hardness, so in low-heavy-metal water supplies a single cartridge can last up to 2–3 years, typically 12–36 months.
- Rated for point-of-use flow rates. Most effective at flows up to 4 L/min, which suits protecting a single fixture or appliance rather than whole-house flow rates.
One Stop Plus™ — Applications
The 10″ x 2.5″ One Stop Plus™ cartridge is ideal for Point-of-Use installations protecting individual appliances and fixtures, including:
- Espresso Coffee Machines
- Baths, Showers, and Sinks
- Hot Drink Machines
- Boilers or Steamers
- Liquid Circuit Cooling Systems
One Stop Plus™ — Water Chemistry Limits
The One Stop Plus™ system is a finished product, ready to install. It requires a standard 10″ x 2.5″ slim-line filter housing.
Please note that pre-filtration will be required if your water falls outside the parameters below:
