Carbon filters are commonly used in kitchen ventilation systems to remove odours, smoke, and other pollutants from the air. Carbon filters work by adsorbing (not absorbing) organic compounds, such as cooking odours, as they pass through the filter.

Activated carbon filters are the most commonly used type of carbon filter in kitchen ventilation systems. Activated carbon is a highly porous material that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. These pores increase the surface area of the carbon, allowing it to adsorb more pollutants from the air.

As air from the kitchen passes through the activated carbon filter, the organic compounds in the air are attracted to and adsorbed onto the carbon surface. The longer the air remains in contact with the carbon, the more effective the filter will be at removing pollutants from the air.

Carbon filters are typically used in conjunction with other types of filters, such as grease filters, to provide a comprehensive solution for cleaning the air in a kitchen ventilation system. While carbon filters are effective at removing organic compounds and odours, they are not effective at removing particulate matter, such as smoke, grease, and dust, which can clog the carbon filter and reduce its effectiveness over time. Therefore, it’s important to have a proper maintenance schedule and replace the filters as needed to ensure the kitchen ventilation system operates efficiently and effectively.
