The water filter shown here uses the same filter unit, but is available in several kit versions to suit your setup. The right choice depends mainly on the type of tap you wish to use and the accessories you want included with the filter.

An under-sink water filter is designed to improve the quality of the water used in the kitchen every day, without taking up space on the worktop. It is a discreet, practical and sustainable solution for households that want better-tasting tap water.
The right approach isn’t simply to look for “the best purifier”, but to start with your actual needs: improving the taste, reducing certain odours, filtering drinking water more effectively or simply having a more convenient solution than a filter jug.


This air purifier uses a single 4-stage filter cartridge. Mechanical filtration traps unwanted particles, whilst the high-density activated carbon helps reduce various compounds often sought after by water purifier users: chlorine, certain odours, chemical residues, heavy metals and other pollutants that may be found in water.
In this product, the ultrafiltration membrane has a pore size of 0.15 microns. This fine pore size enables highly effective filtration whilst maintaining a compact design that is easy to install and practical for everyday use.
Another key advantage is that, unlike a reverse osmosis system, this system retains the minerals naturally present in the water and better preserves its natural taste, whilst avoiding the waste water associated with reverse osmosis.
The purifier is designed for simple domestic use. The cartridge has a long service life and can last for several years, depending on household usage and the quality of the incoming water.
The system is popular for its ease of use: no large, visible installation, no bulky machine on the worktop, and purified water available straight from the tap.
| Version | Contents | Who is it for? |
|---|---|---|
| Without accessories | Complete water filter unit with cartridge fitted and bracket, excluding fittings, tubing and tap | For those who already have the equipment or who want to put together their own customised setup |
| 4-in-1 | The same air purifier, supplied as a ready-to-install kit with all the necessary accessories and a small dedicated tap to be fitted alongside the existing tap | For households looking for a complete kit without replacing their current mixer tap |
| With a 3-way tap | The same water filter, supplied as a complete set including fittings, tubing, a T-joint and a three-way mixer tap | For households looking for a more integrated system with a single main tap |

This water purifier is popular with many households because it offers highly effective filtration without relying on reverse osmosis. It retains the minerals naturally present in the water and avoids the usual drawbacks of reverse osmosis systems, such as wastewater discharge and the often more cumbersome installation process.
For everyday domestic use, this is therefore an ideal solution if you’re looking for the right balance between fine filtration, ease of use, simplicity and preserving the water’s natural taste.

The filter unit is the same. What differs are the accessories included: a basic version without fittings or a tap, a standard kit with a small additional tap, or a kit with a three-way tap to replace the existing tap.
No. The standard 4-in-1 kit is designed to add a small tap specifically for purified water, in addition to the existing tap.
The three-way tap is ideal if you want to replace your existing tap and use both tap water and purified water from a single tap, creating a more integrated setup.
The version without accessories includes the complete water purifier with its cartridge and stand, but does not include screw-in fittings, tubing or a tap.
The main advantage is that it filters the water thoroughly whilst retaining its natural minerals, with a simpler installation process and without wasting water, unlike a reverse osmosis system.
