Blade hand dryers are super efficient, thanks low energy consumption. Those modern types of hand dryers are a good alternative for classic hand dryers. They provide great experience by drying hands only in a few seconds. What is more instead of heated air they use strong air stream to scrape water off hands. The water is collected in a collection tray to protect floor from getting wet. Manufacturers recommend blade dryers with HEPA filtration. The filters clean the air stream from bacteria and therefore provide the most hygienic hand drying solution. In washrooms that require higher hygienic standards the best devices are products with antibacterial cover. Airblade dryers prices are higher, but at the same time they reduce overall operating costs.
