In recirculation mode, the hood draws in the air saturated with smoke and odors, filters it and returns it to the kitchen. In the event that air outlet to the street or to the ventilation shaft of the house is not available, recirculation can be betterdecision. In this case, the air saturated with smoke and odors passes through the charcoal filter, which retains all impurities, and returns back to the kitchen.
Recirculation hoods are often used in apartment buildings, where venting outside is often problematic. Depending on the intensity of use of the hood, the charcoal filter should be replaced once or twice a year.
Today, the kitchen has become the “community center” of the entire home, so special attention is paid to the noise level of the hood. Over the past years, taking into account the increase in the power of kitchen hoods, we carefully select sound insulation materials.
Here are some tips for reducing noise:
• Use a round, smooth, flexible duct, as the air passing through corrugated ducts produces more noise.
• Observe the diameter of the air duct opening.
• Install the duct with as few bends as possible.
• The duct can be additionally insulated to reduce noise and avoid condensation.
