4-Way Kitchen Taps – A Choice Between Nature and Technology

Did you know you can have access to two different types of filtered water from a single tap? Four-way faucets are a solution for conscious users who want to decide what water they drink at any given time. They allow the use of tap water (hot/cold) and offer a choice between pre-filtered water (rich in natural minerals) and water perfectly purified by reverse osmosis.

Two faces of filtration – you decide

This solution combines the benefits of a classic carbon filter with advanced reverse osmosis. Thanks to two independent filtered water circuits, you gain:

  • Channel 1: Pre-filtered Water (Natural Minerals): Water passes through pre-filters (e.g., carbon filters) only. It is purified of chlorine, sand, and odors, while retaining 100% of the natural minerals (calcium, magnesium) found in tap water. Perfect for cold drinking for those who appreciate a natural taste.
  • Channel 2: Reverse Osmosis Water (Perfect Purity): Water flows through an osmotic membrane, which removes everything—including limescale, viruses, and heavy metals. It's crystal-clear and soft. Perfect for boiling water in the kettle (no sediment!), coffee makers, irons, and humidifiers.

Intelligent 2-in-1 design

Our 4-way faucets are a masterpiece of functionality hidden in an elegant form:

  • Independent zones: The pipes inside the spout are separated. Raw water, mineral water, and reverse osmosis water never mix.
  • Dual controls: The right lever is for mains water (hot/cold). The left lever (or knob) lets you select the type of filtered water: turn one way for "minerals," the other for "osmosis."
  • Aesthetics: Despite supporting up to four stream types, the faucet fits into a standard sink hole (35 mm).
4-Way Tap: Water with Natural Minerals and Pure RO from One Tap
One tap, four functions: Cold, Hot, Natural (pre-filter), Pure (Osmosis).

Who is this solution for?

Four-way faucets are ideal for systems with membrane bypasses or advanced hybrid filters. They're a great choice if you want to conserve both the osmotic membrane and water by using tasty carbon-filtered water for drinking, and only use osmosis for cooking.

Frequently asked questions

  • Number of filtered water connections.

    • 3-way faucet:It has one input. It mixes the water from the filter into a single stream.
    • 4-way faucet:It has2 independent entrancesThis allows the water to be separated into pre-filtered water (with minerals) and full osmosis water (without scale).

  • Depending on how your filter is connected, you will typically get:

    1. "Mineral" water (after pre-filter):Purified of chlorine, but retaining its natural elements. Drinkable.
    2. "Technical/Pure" water (after osmosis):99% free of limescale and impurities. For kettles and coffee machines.

  • NO.Four-way taps have a standard installation diameter (35 mm), the same as regular kitchen taps. They fit any standard sink, replacing your old tap.

  • The battery has an additional handle (usually on the left side).

    • The one-way movement opens the channel with water after pre-filtration.
    • Movement in the opposite direction opens the channel for water after osmosis.
      It is very intuitive.


  • No. Separate channels are used inside the faucet. Tap water (untreated) flows through a separate path and does not come into contact with filtered water until it exits the aerator.

  • Fits any filter that has an output for two hoses (e.g.Philips AUT4030R600). If you have a simple filter with one outlet, you can connect a 4-way tap using a T-connector (the same water will flow from both sides), but you'll use its full potential with dual-function systems.
