Ventless appliances are devices that do not require external ventilation to operate. They are designed to recirculate air within a space, making them ideal for areas where traditional venting is impractical. Common examples include ventless dryers, induction cooktops, and electric heaters. These appliances often use filters to clean the air before recirculating it, ensuring a safe and comfortable environment. One of the main advantages of ventless appliances is their flexibility in installation. Since they do not need ductwork or external vents, they can be placed in various locations, including small apartments or homes without existing ventilation systems. This makes them a popular choice for urban living and energy-efficient designs.
