Air purifiers are built with internal fans that pull air from closed spaces in your home or office, through filters that collect harmful particles like dust, pollen, and bacteria. There are also air purifiers that use ultraviolet radiation to destroy the DNA of viruses and bacteria, which neutralizes them. Once the air has been purified, it circulates back into the room, and the process is repeated continuously to keep a healthy indoor environment.
Air purifiers can help limit the spread of infectious diseases like coronavirus. Droplets that contain the virus can be captured by filters, and the virus itself can be neutralized with ultraviolet radiation.
A sneak peek at the innovations that will change our everyday lives in the future.
