Using the Dyson Airblade dB AB14 - W is easy. Just place your hands into the dryer, and it'll quickly dry them in 12 seconds. Make sure to keep your hands within the designated area for the best results. When it comes to maintenance, the HEPA filter needs to be replaced regularly to keep it working effectively. Check the filter's condition every few months. Keep the dryer clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners as they may damage the polycarbonate ABS white finish. In high - traffic areas, you might need to check the dryer more frequently to ensure it's functioning properly.
