This survey was conducted by Shaun Kranish - "The EMF Explorer", owner of ElectraHealth.com.  The survey was designed to be as scientific as possible, but undoubtedly there are flaws.  The survey was sent out to ALL current subscribers of the ElectraHealth newsletter.  It was also posted on other websites open to the general public.  One potential flaw may be that some customers who returned the filters may also have unsubscribed from the emails and therefore not given the opportunity to respond.  We had no way to control for this though - we had to follow the spam rules and we respect our customers wishes above all else.

The questions and the results were as follows:

Question: What was your (or you family's) experience with the filters?
