Research conducted at the University of California at Davis has shown that a Beam system provides relief from major allergy symptoms...as much as 61%! Unlike conventional vacuums that can recirculate dust, a Beam system removes 100% of contacted dirt, dust mites, dander, pollen and other allergens from the living areas in your home...to relieve the misery caused by allergies.
A Beam DVS is superior to a conventional vacuum in providing relief from allergy symptoms.
Study results were published in an article entitled "The Influence of a Ducted Vacuum System on Quality of Life in Patients with House Dust-Associated Allergic Rhinitis", which appeared in the Journal of Investigational Allergology and Clinical Immunology*. The study was conducted under the auspices of Stanley M. Naguwa, M.D., and M. Eric Gershwin, M.D., both of the Division of Rheumatology, Allergy and Clinical Immunology, University of California at Davis School of Medicine, Davis, CA, USA.

Non-Nasal/Eye Symptoms: Patients who used ducted vacuum systems rated the severity of fatigue, thirst, reduced productivity, tiredness, poor concentration, headache or feelings of being worn out, 48 percent less than the baseline and 46 percent less than when they used a traditional vacuum.

Eye Symptoms: Patients who used ducted vacuum systems rated the severity of itchy, watery, sore and swollen eyes 61 percent less than the baseline and 60 percent less than when they used a traditional vacuum.

Sleep Symptoms: Patients who used ducted vacuum systems rated the severity of sleep symptoms including difficulty getting to sleep, waking up at night and lack of a good night's sleep, 44 percent less than the baseline and 49 percent less than when they used a traditional vacuum.
