Plasma Technology for Cooker Hoods
Plasma technology is an advanced air purification system that allows a cooker hood to operate in recirculation mode, without the need to expel the air outside the home.
The air extracted by the cooker hood first passes through the grease filters and then through the Plasma module, where the molecules responsible for odours are treated. The purified air is then released back into the room.
With Plasma technology, Galvamet offers a particularly effective solution for reducing cooking odours without the need to install an exhaust duct to the outside.
What is a Plasma filter for a cooker hood?
A Plasma filter for a cooker hood is an air treatment system used in recirculating installations.
Unlike traditional activated carbon filters, which progressively adsorb the substances responsible for odours, the Plasma system uses an ionisation and oxidation process to transform the molecules present in the extracted air.
The Plasma module operates downstream of the grease filters: it does not replace the hood’s metal grease filter, but completes the filtration process before the air is released back into the kitchen.
How does Plasma technology work?
The air treatment process takes place in several stages.
1
Extraction of cooking vapours
The cooker hood extracts fumes, vapours, grease and the molecules responsible for odours generated during food preparation.
2
Grease filtration
The air passes through the metal grease filters, which capture a large proportion of the grease particles.
3
Plasma treatment
The air then passes through the Plasma module. Through an ionisation and oxidation process, the molecules responsible for odours in the extracted air are treated.
4
Final purification
The process is completed through the final filtration stage of the Plasma module before the air is released back into the room.
5
Air released back into the kitchen
The treated air is released back into the kitchen.
Why choose a cooker hood with Plasma technology?
A cooker hood with Plasma technology combines the advantages of a recirculating installation with highly effective odour reduction.
Up to 95% odour reduction
Plasma technology can achieve up to 95% odour reduction, delivering higher performance than traditional activated carbon filtration systems.
Up to 10 years of service life
The Plasma module is designed for a long service life and can operate for up to 10 years without the periodic replacement required by traditional activated carbon filters.
No external exhaust duct
The air is treated and released back into the kitchen, so no duct is required to expel the air outside. This provides greater freedom in kitchen design and makes recirculating installation possible even when an external exhaust duct is difficult or impossible to install.
Reduced maintenance
The long service life of the Plasma system reduces the need for filter replacement and the associated costs over time.
Air treatment
The Plasma process also contributes to the treatment of microorganisms present in the extracted air, with values of up to 99% under the conditions specified in the relevant tests.
Plasma filter or activated carbon filter?
Both technologies allow a cooker hood to operate without an external exhaust duct, but they work in different ways.
| PLASMA TECHNOLOGY | TRADITIONAL ACTIVATED CARBON | |
|---|---|---|
| Odour reduction | Up to 95% | Lower than Plasma |
| Operating principle | Treatment of molecules through ionisation and oxidation | Adsorption of odours |
| Duration | Up to 10 years | Periodic replacement |
| Maintenance | Low | Filter replacement |
| Recurring costs | Reduced | Periodic purchase of filters |
| External exhaust required | No | No |
Plasma technology is particularly suitable when high odour reduction efficiency, long service life and reduced maintenance are required compared with traditional activated carbon filtration systems.
Ducted or recirculating cooker hood with Plasma?
A ducted cooker hood expels the extracted air outside through a duct. When an external exhaust can be installed correctly, this remains an effective solution. However, bends, duct length and diameter can affect extraction performance.
Expelling the air also means losing air that has already been heated in winter or cooled in summer. The expelled air must be replaced with air from outside, increasing the energy required to heat or cool the room.
A recirculating cooker hood with Plasma technology, on the other hand, treats the air and releases it back into the kitchen without requiring an external exhaust. This prevents conditioned indoor air from being expelled, helping to limit energy losses.
The absence of ducting also provides greater freedom in kitchen design, particularly for islands and renovation projects.
When is a cooker hood with a Plasma filter a good choice?
Plasma technology can be particularly suitable when:
Galvamet Plasma Technology
Galvamet integrates Plasma technology into various types of cooker hoods and kitchen extraction systems.
The aim is to combine extraction performance, effective odour treatment and design freedom, offering an advanced alternative to traditional recirculating installations with activated carbon filters.
Plasma technology is available on a range of Galvamet products, from traditional cooker hoods to extraction systems integrated into the hob.

Frequently Asked Questions about Plasma Technology
It is an air purification system used in cooker hoods operating in recirculation mode. The extracted air passes through the grease filters and then through the Plasma module, which treats the molecules responsible for odours before releasing the air back into the kitchen.
The Plasma filter treats the air through an ionisation and oxidation process. The molecules responsible for odours in the extracted air are treated before the air is released back into the room.
Plasma technology guarantees odour reduction of up to 95%, as demonstrated by tests carried out by IMQ in accordance with EN 61591. (IMQ Test Report No. PE16-0001087-01. Test performed on a Galvamet product equipped with a Plasma filtration system. Measured odour reduction factor: 94.4% at maximum speed.)
The Plasma module is designed for a long service life and can operate for up to 10 years under the conditions specified in the relevant tests, without the periodic replacement required by traditional activated carbon odour filters.
The Plasma module is designed for a long service life and can operate for up to 10 years. It therefore does not require the periodic replacement typically needed with traditional activated carbon odour filters.
Activated carbon captures odours mainly through an adsorption process and requires periodic filter replacement. Plasma technology, on the other hand, treats the molecules responsible for odours through ionisation and oxidation processes, providing high odour reduction efficiency, long service life and reduced maintenance.
No. A recirculating cooker hood with Plasma technology treats the extracted air and releases it back into the kitchen, without requiring an external exhaust duct. The grease filters specified for the cooker hood are still required.
No. Plasma does not replace the grease filters. The extracted air first passes through the metal grease filters, which capture a large proportion of the grease particles, and is then treated by the Plasma module.
