A Beam Central Vacuum System is the built-in cleaning appliance that lets you clean your home and improve indoor air quality at the same time. Research at the University of California at Davis has proven that a Beam system provides relief from major allergy symptoms...as much as 61%. Recent product enhancements provide peak performance for life. They include a more powerful, higher-efficiency motor, a new secure seal system, and a new HEPA CleanStream™ Filtration System, which is five times stronger than other leading filtration media.
