Stetzerizer Filters – Additional Installation Notes


  1. For best results, make sure you turn your electronic devices ON during filter installation – especially televisions and computers.
  2. Install two (2) Stetzerizer filters where each computer and each television in the home is located. If you have Plasma TV’s you will need to install three (3) filters where each of those is located. You will likely need power strips and/or tri-tap adapters (electrical tees) in order to accommodate the filters. Installing filters in these locations first will lower readings throughout the house and should result in using fewer filters overall. Then move on to testing with the Microsurge meter and finishing the install.
  3. After Step 2 has been completed, pick an outlet to start testing with the Microsurge meter – we usually start in a bedroom. Plug in the Microsurge meter and note the number on the LCD display (expressed in GS units). Plug in 1 Stetzerizer filter to the same outlet and note the number on the meter again.
  4. 4. If you see a reduction in GS unit readings of 20% or more, leave the filter in that outlet and unplug the meter. Move on to the next outlet and repeat the same process.
  5. If you did not see a reduction of 20% or more, remove the filter and the meter – you do not need a filter at that particular outlet. Move on to the next outlet and repeat the same process.
  6. Continue these steps until you have tested every outlet in your home – including the garage and basement, but excluding outdoor outlets – and installed filters where they are needed. The average house needs about 20 Stetzerizer filters – you may need more if you have more electronic devices in your home.
  7. Note: Save the kitchen for last; there are normally fewer outlets in the kitchen, so having them filled with filters is inconvenient. There are also other problems that can present themselves in the kitchen, or even in other rooms of the home. The most common thing we see is outlets having a shared neutral wire; steps to resolve this issue follow:
  1. Say you are testing an outlet and you have the Microsurge meter plugged into the bottom half of the receptacle. Normally you would plug in a Stetzerizer filter to the top half of the receptacle and the GS unit reading on the meter would decrease. However, at this outlet you find that when you plug in the filter the meter reading increases; this indicates a shared neutral.
  2. To properly filter this outlet, you’ll need 2 powerstrips or electrical tees. Plug one powerstrip into the top of the receptacle, and another into the bottom receptacle.
  3. Plug the Microsurge meter into one of the powerstrips and note the GS unit reading. Then plug a filter into that same powerstrip – you should see the GS unit reading decrease this time. Repeat this process in the other powerstrip.
  4. You’ll end up with a powerstrip and a filter plugged into both the top and bottom halves of the receptacle, and your shared neutral problem is solved.
  1. Another thing to look out for is switched outlets – outlets controlled by a light switch. These are most common in the living room, but other rooms may have them as well. Be sure that you do not install Stetzerizer filters in the “switched” portion of a switched outlet, as turning the outlet off would effectively remove the filter from your installation.
  2. Once this process has been followed you should be able to go back to any outlet in your home and see GS readings of 50 or less (35 or less is ideal).


Testing for “bad” light bulbs

1) Tools needed: floor or desk lamp, Stetzerizer Microsurge meter

2) Install the light bulb you wish to test in the floor or desk lamp, and plug the lamp into an outlet.

3) Plug the Microsurge meter into the same outlet and note the GS unit reading on the display.

4) Turn the floor/desk lamp on and note the GS unit reading again. If it increased by more than a few points, the light bulb is a generator of dirty electricity – you don’t want to use it in your home.

Magda Havas, Ph.D., Environmental & Resource Studies Program at Trent University.


Last January I received a phone call from Michelle Illiatovitch in Toronto who told me that both she and her daughter, Kestra, were electrically sensitive. Shortly after some renovations Kestra began to feel ill. She noticed that the lights in her bedroom were flickering so they called in an electrician who corrected the problem that related to the loose wires in the fuse box. Kestra’s health improved dramatically but she still felt tired and had frequent, headaches, fuzzy thinking, depression, chest pain and nausea.


Michelle’s niece, Catherine, developed chronic fatigue shortly after moving to a farm in Wisconsin. She read that some farmers in her area were experiencing health problems and they were also having difficulty with their dairy herds and that Dave was helping the farmers solve their problems, which were electricity-related.


She contacted Mr. David who told her to turn the power off in her home. She did this and began to feel better almost immediately. She then purchased some of his equipment to measure her home and to filter out the dirty electricity. Shortly after installing the electric filters, also known as capacitors, her health began to improve. She was so impressed she contacted her Aunt Michelle to share the good news.


Michelle also bought some filters, which plug into an electrical outlet, and installed them in her home. Not only did her health improve but the health of everyone improved including her dog and her husband.


Kestra was feeling much better at home but when she went to school she became ill again. Michelle asked the school principal if she could install some filters in the school to help her daughter. Joy Kurtz, the Principal of Willow Wood School agreed.

That’s when Michelle phoned me.


She wondered if I would do a study to determine the effectiveness of these filters. I was familiar with electrical-sensitivity but it was my understanding that a very small percentage of our population is likely to be electrically-sensitive and because the symptoms are so vague it’s difficult to know if it’s indeed electrical-sensitivity or something else that’s causing the problem.


The symptoms for sensitivity vary. Some develop headaches when they go shopping in stores that have bright halogen lights. Others become tired or can’t think clearly. Some develop skin rashes after using a computer. In severe situations people can even loose consciousness. Generally those with electrical sensitivity prefer incandescent lighting to fluorescent lighting.


I was skeptical this study would show anything partly because I was skeptical about the effectiveness of the filters and partly because I felt the population of teachers and students was too small. But I was also intrigued and agreed to design a questionnaire.


No one in the school, apart from the Principal and the head Custodian, knew what we were doing. It was necessary to keep the teachers in the dark initially so that psychological bias would not play a role in the answers they provided. This is referred to as a “blind” experiment.


We measured the electromagnetic environment in the school with and without the filters. The filters removed many of the microsurges on the electrical wiring in the school but did not change the electric or magnetic fields, which were already low. These microsurges consist of high frequency energy on an electrical wire and are generated by various appliances and equipment.


At the end of the study that lasted 6 weeks, 3 weeks without and 3 weeks with the filters, I received several boxes of completed questionnaires. The real work began.


I analyzed the teacher results first and was amazed by what I found. Of the more than 40 teachers, 26 responded regularly. Of these 26, 4 did not change, 4 were slightly worse and 18 improved while the filters were installed. In decreasing order of magnitude this is what we found. While the filters were installed, 46% of the teachers experienced less fatigue, 42% were less frustrated, 35% were more satisfied with their work, 35% had a greater sense of “well-being”, 27% were less irritable, 23% had more energy, 23% experienced less body pain, and 19% had fewer headaches. And all of this occurred during February, a month we normally associate with the “blahs.”


Preliminary analysis of the student results shows that both high school and elementary students improved more during the afternoon than in the morning. In elementary school, student disruptions were reduced by an average of 3 to 4 minutes per class, which allows more teaching time. The high school results were less conclusive.


While the results are encouraging and suggest that these filters can improve the school environment, it’s necessary to repeat this study at other schools to see if the results are consistent. If they prove to be consistent then we may now have a tool to improve our electrical environment at home and at work. Just as we have air filters to remove airborne particulates and water filters to remove chemicals in our drinking water, Dave has designed a filter that reduces indoor electrical pollution associated with electronic devices like computers and variable speed motors.


At a recent talk at Willow Wood School in Toronto, Mr. David said this filter would even reduce some of the microsurges entering your home from your neighbor next-door. His work on dairy farms in Wisconsin resulted in healthier cows and higher milk yields. While these filters are not the answer to all of our electrical problems, they may make living more tolerable for the small percentage of the population who are truly electrically-

sensitive and, if our results are correct, they may improve the quality of life even for those of us who aren’t.
