With an environmentally-friendly dryer, you make an energy-efficient and sustainable choice. All environmentally-friendly dryers have a self-cleaning condenser. This automatically rinses itself after each dryer cycle, so you always dry energy-efficiently. These dryers are also made from more durable materials, so they have a mid-range or high-end build quality. This way, you know the dryer lasts extra long. Environmentally-friendly dryers always have a C energy label or higher. This saves you about € 20 on your annual energy bill on average.
