Modern hand dryers have the option to be installed with HEPA filters, which are certified to remove a high percentage of particulates from the surrounding environment. For example, 99.99% of viruses are removed from the air with XLERATOR hand dryers that feature HEPA filters. High-speed hand dryers with HEPA filters are the best defense against the spread of bacteria, outweighing both paper towels and conventional hand dryers. If your unit uses a HEPA filter, the filter should be replaced every 6 to 12 months.
Wall guards can also be used in conjunction with HEPA filters to keep the surrounding area hygienic. Wall guards feature antimicrobial designs that protect your walls from water droplet stains and other residue. This prevents bacteria from building up.
