GS Filters improve Power Quality & Health

Havas, M. and D. Stetzer. 2004. Graham/Stetzer Filters Improve Power Quality in Homes and Schools, Reduce Blood Sugar Levels in Diabetics, Multiple Sclerosis Symptoms, and Headaches. International Scientific Conference on Childhood Leukaemia, London, 6th –10th September, 2004


Graham/Stetzer filters significantly reduce radio frequency electrical noise on indoor wiring generated by computers, energy efficient lighting, dimmer switches, and entertainment units within the home or workplace and transported into buildings by power lines from neighbouring property. The resultant improvements in power quality in homes and in schools are associated with fewer and less severe headaches, more energy, lower blood sugar levels for diabetics, and improved balance for those with multiple sclerosis. Results are observed within a matter of hours or days. Cases studies for blood sugar, multiple sclerosis, and general wellbeing are presented.
