Juno JDU2322E is a cooker hood designed to efficiently remove cooking odors and grease from the air. It features two operating modes: external exhaust and internal recycle. The external exhaust mode vents air outside through a 120mm pipe, while the internal recycle mode purifies air using a rectangular carbon filter and releases it back into the room. The hood has three speed settings, allowing you to adjust the extraction power to your cooking needs. It also comes with a metal grease filter that is dishwasher safe for easy cleaning.
