What does a Vacuum Cleaner do that an Air Purifier doesn’t? Nothing. They’re both the same machine, just with slight modifications made to the layout of components, and the intensity of the internal fan. Purifi is a handheld vacuum cleaner that can be used to suck in household dust and dirt, but once you dock it in its charger, it powers on a low-intensity mode to purify air. The paper filter/bag that collects dust is replaced by a HEPA filter that absorbs the dirt, and can be washed clean and used again. Neat! Designer: Nicole Assini
