Using this hand dryer is a breeze. Just place your hands under the dryer, and it will automatically start. You can adjust the air temperature and speed to your liking using the controls on the dryer. When it comes to maintenance, check the HEPA filter regularly. If it looks dirty or clogged, you can easily access the separate chamber where the filter is housed and replace it without having to disconnect the dryer. Make sure to keep the dryer away from water sources to prevent any electrical hazards. If you have any issues, the 5 - year warranty means you can get help from the manufacturer.
