Hand dryers are worth it for commercial washrooms because they can cut drying costs compared to constantly buying and restocking paper towels. Modern hand dryers can produce a lower carbon footprint over their lifespan because they can be more efficient than relying on single-use paper towels. The downside is that paper towels are a better option for removing germs and reducing the spread of microbes compared to hand dryers. If you’re concerned about germs, you can stock up on disinfecting wipes and hand sanitizer.

Yes, hand dryers are considered safe and sanitary for everyday use. When used with proper handwashing techniques, they can remove most germs from your hands. However, when used with improper handwashing techniques, hand dryers can blow bacteria onto your hands or around the washroom. You can also use paper towels to dry your hands and hand sanitizer to help kill germs.

Hand dryers work by using an electric motion sensor when your hands are underneath to turn on a fan and motor. The fan and motor pull in air from the washroom and blow it out onto your wet hands to remove moisture. The air passes over a heating element like a hot metal coil to warm it up. They are a great way to dry your hands, along with paper towels and napkins.

Drying your hands properly after using the washroom is important because wet skin can transfer bacteria and other germs more easily than dry skin. Drying your hands properly reduces the chance of germs spreading, and the physical act of rubbing your hands dry can remove lingering bacteria or dirt. To ensure your hands are clean, use hand soap to thoroughly wash your hands and use a hand dryer or paper towel to dry them. Avoid using your clothes because dirty clothes can recontaminate your hands.
