Passengers waiting for planes, trains and buses frequently collect and wait in bus stops, train stations and airport waiting areas sharing germs from their mouths and clothes and those areas into germ hotshots, especially on rainy and cold days. Millions of people every day stand in or sit on benches just in bus stops transferring their germs and picking up others as they wait and breathe.
By installing a Safety Halo® from the ceiling of the bus or train stop, you can provide an effective layer of protection around the people inside and help protect them. The Safety Halo® works by pulling the dirty germ-filled air into its housing to filter it. There it has a pre-filter at the point of entry that extracts dust particles from the air. The air then flows through a HEPA filter element to clean out germs and other tiny contaminants. After passing through the HEPA filter, the air then gently flows out the bottom of the Safety Halo® to create a cone of clean air around the person in the station or terminal.
This cone of HEPA-filtered air, which is gently pressurized so that it moves outward as it flows downward, helps to block the entry into itself of air exhaled by others in the same area. It also captures many of the respirated particles that penetrate the cone, and as an added benefit, germs and other particles exhaled by the person inside the cone of protection.
As an option to reduce maintenance and other operating costs, We Clean Air can replace the standard pre-filter and blower section in the Safety Halos® with an Air Cleaning BlowerTM (ACB). ACBs clean and blow air without using filter media, and they remove dust, pollen, mist, rain and millions of other particles. Hence, they move cleaned air into the HEPA element to extend its life. By replacing the pre-filter elements in the Safety Halos®, ACBs eliminate their gradual clogging, thereby reducing the maintenance of Safety Halos® still further.
