I agree with the idea that electrification and zappers do not lower immunity. I have been zapping since 2000 and frequently have my blood tested. There has not been any significant change in my blood work in the last 11 years. I do not, however, zap as frequently as you do. At this point in time, my health is so much improved that I only use the zapper when there is an obvious need such as an abscess, flu symptoms, etc., or for occasional cleansing.
Additionally, while I do not have any studies to support it, I believe that one of the effects of using the zapper ( Clark zapper at least ) is that the zapper can boost the immune system which may have been lulled to sleep. I do not see any reason why the Beck Blood Electrifier would not have some of the same effect in addition to destroying microbes.
