Designed for excellence
From eye care to comfortable typing, ExpertBook B3 Detachable offers excellent features to improve everyday experiences, including plenty of innovative features and enhancements that boost productivity and comfort.
The surface of any laptop harbors thousands of potentially harmful bacteria. To keep your ExpertBook B3 Detachable hygienic, the keyboard, touchpad and palm rest are all protected with an antibacterial treatment8,9.

ASUS Antibacterial Guard is also made to withstand alcohol-based cleaning products and hypochlorous acid water10, so the surface of your laptop stays clean and sanitary — limiting the spread of harmful bacteria.
