Suprion JS-75e22 eco-friendly salt-free water softener

Suprion JS-75e22: an ecological salt-free water softener for homes with 2 bathrooms and more

The Suprion JS-75e22 is designed for homes that need limescale treatment on a larger water network, typically a house with 2 bathrooms and more. With a capacity of up to 3.4 m³/h, it meets the needs of more demanding installations where a more compact model is not always sufficient.

Its positioning is clear: to offer the expected result of an ecological salt-free water softener, without the constraints of a conventional salt softener. No salt tank, no regeneration, no wastewater discharge, no electrical connection, but a durable technology that is easy to live with every day.

How does Suprion work on a higher-capacity installation?

The Suprion JS-75e22 acts in a preventive and curative way against limescale on larger domestic installations. Its action is not chemical: it temporarily modifies the behaviour of limescale in the water, without removing the naturally present minerals and without chemically transforming the water.

This action lasts on average 48 to 72 hours. During this period, limescale remains less adherent, more friable and easier to manage in the pipes, appliances and water outlets of the home. Beyond that, stagnant water in pipes or on surfaces can return to its usual behaviour and reform thin layers of limescale.

This is where the curative power of Suprion becomes so important: in a house that uses more water and places more demand on its network, the unit does not merely limit new deposits. It also helps to reduce, detach and progressively clean the thin layers of limescale when they return. This curative capacity clearly distinguishes it from a purely magnetic system, which is essentially preventive.

Skin, hair, laundry: a clear result in a family home

When the Suprion JS-75e22 is optimally combined with a sediment filter and an activated carbon filter, the effect on comfort of use is clear, including in a house with several water outlets. The skin feels less tight, itching sensations linked to very hard water are greatly reduced, hair feels better and laundry comes out softer after washing.

The softness achieved is comparable to that of a salt softener set around 10 °TH, with one major difference: this remains an ecological salt-free water softener, without wastewater discharge and without heavy maintenance. That is exactly why this model is attractive for households seeking a real comfort improvement without the constraints of a conventional softener.

It is however important to distinguish limescale from soap, shampoo or washing-product residues. These residues can leave marks on surfaces, but they are not limescale. Suprion acts on limescale; it does not replace normal cleaning of surfaces.

Why should this model be combined with good filtration?

On a larger-capacity installation, overall consistency is even more important. Suprion acts on the behaviour of limescale, the sediment filter retains particles, fragments of deposits and network impurities, and the activated carbon filter improves the water in terms of taste, odour and comfort of use by retaining chlorine and other irritating compounds.

This combination delivers a clearer result for skin, hair, laundry, taps, surfaces and the overall stability of the installation. The filter should therefore not be seen as a simple addition: it is part of the logic of optimal system performance.

Why choose the JS-75e22 rather than a more compact model?

The JS-75e22 is the right choice when you want to treat a larger domestic network with several water outlets used daily. Where a more compact model is intended for a standard home, the JS-75e22 is aimed at a house that requires more capacity, more stable flow and more comfort across the whole installation.

Its positioning makes it a particularly coherent solution for families, homes with several bathrooms or properties looking for an ecological salt-free water softener capable of handling heavier daily use.

SUPRION performance

The current product sheet also highlights a global performance logic with 3-in-1 capabilities: descaling, anti-oxidation and anti-sludge. The technology is designed to significantly reduce limescale deposits while helping to limit corrosion of metallic elements within the installation.

After a few months, it is possible to observe that a thin layer of partially dissolved limescale remains deposited inside the pipes. This thin layer then plays a protective and preventive role against rust, contributing to the overall balance of the installation.

Benefits of the JS-75e22 model

• Suitable for homes with 2 bathrooms and more
• Maximum flow rate up to 3.4 m³/h
• Installation on 22 mm copper pipe or on a 20/27 (3/4") standard fitting with the optional kit
• No salt: no refill and no regular handling
• No electricity: no electrical connection required
• No wastewater discharge: no rinse water or wastewater linked to operation
• WRAS-certified technology and validated by British Gas

For what type of home?

This model is intended for domestic use for treating a maximum water flow below 3.4 m³/h. This flow corresponds to a pipe with an inner diameter of 28 mm or less. In practice, this generally corresponds to a home with 2 bathrooms and more.

If the main supply pipe is larger, it is preferable to check the real maximum flow rate of your home before choosing this model.

Technical specifications

Installation and fitting

The Suprion JS-75e22 is designed to be installed on 22 mm copper pipes and is equipped with compression fittings at each end. A plumber can easily adapt the 22 mm diameter to the actual diameter of the existing pipe.

For greater simplicity, an optional mounting kit can be added. It allows the Suprion to be directly adapted to a standard 20/27 (3/4") plumbing fitting. For optimal performance, it is recommended to combine the unit with a backwash filter or a double water filter.

A proven technology

The Suprion JS-75e22 is based on a technology already used on a large scale. The product is WRAS certified and the SUPRION range is also highlighted for its validation by the national energy distributor in the United Kingdom: British Gas.

SUPRION technology is also presented on your website as being manufactured in Japan for more than 20 years and already used by major companies and institutions such as Toyota, Hitachi, Mitsubishi, Panasonic, the University of Tokyo and Ashiya Municipal Hospital.

This long track record, these installation references and the many positive returns reinforce Suprion's positioning as a real ecological salt-free water softener alternative for homes that want to treat limescale durably without the constraints of a salt softener.
