High-speed hand dryers are devices designed to quickly dry hands after washing. They use powerful jets of air to remove moisture, often drying hands in 10 to 15 seconds. These dryers are commonly found in public restrooms and are considered more hygienic than paper towels since they reduce the risk of cross-contamination. Many high-speed hand dryers are energy-efficient and environmentally friendly, as they eliminate the need for paper waste. Some models feature sensors that activate the airflow automatically when hands are placed underneath, enhancing user convenience. Brands like Dyson and Excel Dryer are well-known for their innovative designs in this category.
