Why is there steam in my kitchen cupboard with the AIRLUX AHGB451SI hood?

Question

Accepted Answer

The presence of steam in a kitchen cupboard may indicate that your AIRLUX AHGB451SI hood is not effectively removing moisture. Several elements specific to this model need to be checked to resolve this issue.

First, check the operation and maintenance of the filters: The activated carbon filters (present in recycling mode) should be replaced every 4 months of use, or more often if you cook a lot. The metal grease filters should be cleaned every 2 months and can go in the dishwasher. Clogged or worn filters significantly reduce your hood's suction capacity, and steam can no longer be properly evacuated or filtered.

Make sure you are using the correct speed: Your AHGB451SI hood has 3 operating speeds. The minimum speed (180 m³/h) is designed for quiet ventilation in case of low steam, but it may be insufficient during heavy cooking. Use the medium or maximum speed (up to 390 m³/h) during your cooking for effective steam evacuation. Remember to turn on the hood before you start cooking and let it run for a few minutes afterward.

Check if your hood is operating in exhaust or recycling mode: In external exhaust mode, steam is directly sent outside through a duct of at least 120 mm in diameter. In recycling mode, steam is filtered by activated carbon and returned to the kitchen, which increases ambient humidity. If you are in recycling mode, saturated carbon filters (every 4 months) will no longer filter steam properly. If possible, prefer external exhaust mode for a persistent humidity issue.

Check the installation of the exhaust duct: The outlet pipe must have a minimum diameter of 120 mm, and its path to the outside should be as short as possible. If the duct is blocked, damaged, or has excessive bends, the evacuation will be compromised, and steam will accumulate in your kitchen before condensing in the cupboards. Also, ensure that the backdraft damper does not close the duct.

Improve the overall ventilation of the kitchen: Even with a high-performance hood, a poorly ventilated kitchen accumulates moisture. Open a window while cooking, ensure that vents are not blocked, and check that air can circulate freely. If your kitchen uses a gas appliance, adequate ventilation is particularly important to prevent the return of exhaust gases.

Locate and isolate the cupboard: If your cupboard is very close to the stove or sink, it receives steam directly. Better insulation of the cupboard (door seals, door storage) or moving it away from moisture sources can help.
