ᐅ Is an open kitchen without an external ventilation system advisable? What are your thoughts?

Hello,

we have a brochure for a top-floor apartment. The kitchen is an open plan design within the living area, but it is located internally, meaning it is not adjacent to an exterior wall. The ceiling is open up to the roof ridge, so there is no (horizontal) ceiling. The developer states that venting to the outside is not possible. Whether this is technically true or not still needs to be clarified.

But assuming this is the case, is it actually feasible to operate an open kitchen effectively with only a recirculating extractor hood? Do you have any specific experience with this? What is the current state of technology?

The problem is the sometimes extremely expensive activated carbon filters. For our cooktop, one costs around 120 euros and needs to be replaced twice a year.
I prefer using a vented exhaust system (where possible, of course).

120 euros but only according to the "MSRP," right?

When buying bargains, keep a reserve. I think changing it every 6 months is not excessive if used a lot. Significantly higher ongoing costs cannot be avoided compared to exhaust ventilation, unfortunately that's true.

That would be nice:

Two Bora activated carbon filters for extractor hood, rectangular filter set


And as you say, higher costs are definitely to be expected.

We also have an island, and the exhaust air goes outside through the floor! Our floor structure is 25cm (10 inches) thick, including insulation, and a 10cm (4 inches) high flat duct fits easily within the floor beneath the insulation and the screed!

Exhaust air means an appropriate opening in the masonry.
Perhaps it is not about what is technically possible, but rather that the facade was designed by the architect and must not be altered. With this argument, a friend of mine was also denied a minor modification to a window.

It might technically not be possible if you have a fireplace, controlled residential ventilation, and an exhaust hood. The chimney sweep told us that the pressure switch would trigger an alarm as soon as the exhaust hood is operating.
