I would need to plug a filter into each outlet or just each circuit?

The optimal number of Stetzerizer filters needed for a living space varies greatly. Some of the variables in your electrical system that can determine the number of filters needed are:

  • How many circuits you have
  • How many square feet your living space is
  • The condition of the power grid in your area
  • Your neighbors' electrical usage
  • The electronics in your home (computers, TVs, etc)
  • Appliances and lighting in your home

Our preferred method of choosing the right number of filters looks at the two items in bold above: how many circuits are in your breaker panel and how many square feet your total living space (including garage and basement) is.

Count each physical switch as 1, no matter if that switch is taking up 2 spaces or not. Sometimes you can have 2 switches in one space, so then count both switches. Count all switches, no matter what the switch is for (count your furnace/AC, dryer, everything). Some circuits are 240 volt circuits that we cannot put a filter on. However, other circuits will require 2 filters - where you have electronics such as TVs, computers, etc. So it evens out. Just count each switch that you can turn on/off as 1 and add up the total number you have. Write down or remember this number. We recommend about 1 filter per circuit.

Now, take the approximate number of square feet in your total living space. We recommend about 1 filter per 100 square feet. If the number of circuits is different than the number of square feet divided by 100 (1700 square feet would mean 17 filters for example) then we go towards the lower number. For example, if you have 2000 square feet but only 15 circuits, we would recommend trying 16 or 17 filters.

  1. Start at the biggest sources of dirty electricity – your TV & entertainment areas, your computer areas, outlets closest to dimmer switches, furnaces, etc.
  2. Use your meter and turn things on and off prior to installing filters to identify which devices are the worst. Plug in the meter, and give it a few seconds. It should count up for a few seconds, and then “level off” around an average reading. The reading constantly updates on the meter, but you should be able to get an idea of an average.
  3. Place 1 or more filters (2 recommended for TV and computer areas) into the same outlet – you can use standard outlet adapters and surge suppressors/power strips with the filters too. The filters will make a pop or crackle sometimes when you plug them in – this is perfectly normal and safe, and there is nothing wrong with the filter. The filter is drawing reactive current and the high frequencies to it, so this is normal.
  4. The filters always work best when they are in the same outlet or power strip as devices that are producing dirty electricity. That is to say, the closer the filter is placed to the source of dirty electricity the better.
  5. You’ll notice that installing a filter into one outlet also affects other outlets on the same circuit breaker, reducing the number of filters you need. You do not need a filter in every outlet, but you should check every single outlet.
  6. The numbers will be reduced the best when every circuit has at least one filter on it. Do not leave some areas unfiltered, even if you don’t use that area very often. Leaving an area unfiltered will affect the rest of the house.
  7. You can turn off the power to unused areas and then you don’t need a filter. But if the power is on – make sure that there is at least one filter and no outlets are high.
  8. When we install a filter, it usually reduces the reading from 75-95%. If the reading is 30 or below, then that is great! If the reading is still above 30, try installing another filter. Look for an additional 20% reduction.
  9. For example: If the reading is 500 to begin with, you install 1 filter and maybe it goes down to 50. That is great! A 90% reduction! However, 50 is still not the ideal of 30 or below, so try installing a second filter. That second filter may bring it down to 40 or below. If so, then from 50 down to 40 is a 20% reduction so we recommend keeping the second filter there. If the reading goes down to 47 from 50, that is not a very big reduction so move onto the next outlet.
  10. If you get stuck in one spot and the numbers don’t come down very well – just keep moving around the house and come back to the difficult spot last. Usually the numbers will come down nicely when you have filters throughout the rest of the house.
  11. Avoid using the filters in outlets that are extremely loose. Outlets that don’t grab onto the prongs at all should be replaced with a new outlet for safety reasons.

Other recommendations:

  1. Eliminate the use of wireless devices in the house. If you have a “Smart Meter” – do whatever it takes to get it off your house!
  2. Cordless phone systems, WiFi (wireless Internet) – should be replaced with corded devices.
  3. We also recommend using a TriField Meter (see on our site) to check for current on metal plumbing pipes. This can cause huge magnetic fields in the house. It’s also very easy to fix! The Trifield Meter will also help you locate wiring errors in the house. Wiring errors are very common and cause unwanted and harmful magnetic fields. Read more about wiring errors and "net current" here.
  4. Don’t use dimmers, compact fluorescent bulbs (CFLs), or low-voltage (often halogen is low voltage) lighting. LEDs are also bad – avoid them. We recommend energy-saving clean halogen lighting as a 100% clean alternative to incandescents. Incandescents are great and we recommend them too - but they do use a lot of electricity.
