Integrated fresh air

Geberit DuoFresh with odour extraction unit

The innovative Geberit DuoFresh ensures a new feeling of freshness in the bathroom. The system's secret is hidden behind the wall: at the touch of a button, the air is drawn directly into the WC ceramic and purified with the aid of an active carbon filter. Unlike standard bathroom ventilation systems available on the market, odours no longer have to be masked and are stopped from spreading throughout the room. The hinged flush plate provides easy access to the filter and to the insert for in-cistern blocks.

Trap odours right at the source

Geberit DuoFresh traps odours directly within the WC ceramic and purifies them using an active carbon filter which is concealed behind the flush plate. The system operates independently of ventilation pipes or other ventilation systems, so you don't have to worry about consulting other tradesmen. What's more, the functionality of DuoFresh is not affected by the size of the room.

Geberit Sigma40 – odour extraction unit under high-quality glass

The attractive Geberit flush plate Sigma40 is available in glass or plastic in three colours. It provides quick and easy access to the real heart of the Geberit DuoFresh system. The electronically controlled extraction unit, replaceable active carbon filter and insert for in-cistern block are all located behind the wall: another subtle feature of Geberit DuoFresh.

Insert for in-cistern block

The hinged flush plate provides easy access to the filter and to the insert for in-cistern blocks. The Geberit insert for in-cistern block is already included in the scope of delivery for the Geberit flush plate Sigma40. This allows your customers to insert the in-cistern blocks easily and safely into the concealed cistern, for added freshness and bathroom hygiene with every flush.

Geberit DuoFresh


Good air, good mood

Odour extraction unit

Unpleasant odours in the bathroom and WC are a burden on human relations. Practically everyone has the same reaction: Odours influence the mood.


Right at the source

Quiet fan

With a functional principle similar to that of an extractor hood in the kitchen, Geberit DuoFresh eliminates odours right at the source: in the WC ceramic. A quiet fan suctions them away before they spread throughout the room.


No combating the symptoms

Active carbon filter

Geberit DuoFresh is markedly more effective than conventional solutions such as air fresheners. Unpleasant-smelling air is not simply masked over, but purified by means of an active carbon filter.


Individual operation

At the touch of a button

The odour extraction unit can be switched on as needed. The purified air is returned to the room through the lateral ventilation slots. It switches itself off automatically after ten minutes; it can also be switched off manually beforehand, however.


Better alternative


An open window does the same? Geberit DuoFresh outperforms this conventional method considerably in terms of energy efficiency.


Insert for in-cistern block

Dual hygiene

Geberit DuoFresh is equipped with an insert for in-cistern block that ensures hygienic freshness in the WC.


In a trice

Operating comfort

The active carbon filter is as accessible as the insert for in-cistern block and is thus convenient to replace.


Everything integrated

Easy to install

The special installation frame Geberit Duofix for DuoFresh is equipped with an integrated ventilating pipe for odour extraction. All it takes is an electrical connection and Geberit DuoFresh can also be retrofitted at any time, as all of the other components are installed together with the flush plate.
