A BEAM Central Vacuum System has been clinically proven by the University of California at Davis to reduce allergy symptoms by as much as 61%. A BEAM system is more effective at removing dirt and allergens because it has a larger, more powerful motor than uprights – up to five times more powerful. Unlike conventional vacuums that can recirculate dust, a BEAM Central Vacuum System removes 100% of contacted dirt, dust mites, pollen, dander and other allergens and carries them from living areas to a canister usually located in the garage – to help improve indoor air quality.
