High-Frequency ElectroMagnetic Pollution Removal

Stetzerizer Filters Remove RF Pollution from Household Wiring

High-frequency EMF pollution that is carried in wiring has been shown to be the source of electrical sensitivity symptoms for some people. This high-frequency EMF pollution is produced by common household items such as electric motors (found in hair-dryers, blenders, can openers, etc), loose wires, fluorescent lights, transformers, and especially dimmer switches.

The High-Frequency EM Pollution Reducer (HF EMPOR) designed by Dr. Martin Graham, Professor Emeritus at the Electronics Research Laboratory of the University of California, Berkeley, consists of 20 EMF high frequency suppressors which are simply plugged into ordinary electric outlets, distributed throughout the home or office. These suppressors will measurably reduce the high frequency EMF pollution in your environment.

The suppressors do not use electricity , nor will they interfere with any computers, TV's or other appliances. Installation is simple and enables you to avoid expensive electrician service calls. The suppressors are portable, so you can move them from one site to another. This is NOT a bio-energetic device. Special electronic circuitry simply drains the high-frequency pollution out of the wiring system.

The set of 20 filters will effectively filter an average size home or office. If you have a large home or office, or a large number of EMF high-frequency pollution producers, you may need additional EMF high-frequency noise suppressors. 60 Hz, 120V North-American plug style only.

Filter Dirty Electricity without losing an outlet

GreenWave Filters are the modern approach to dirty electricity mitigation. Dirty electricity is produced by normal household devices, and passed on to other homes through the electrical service. While still using the basic "plug-in" method of other's, these filters boast more efficient and effective mitigation of dirty electricity. They even have a through-plug, so you can still use the outlet! There is a ground prong on these filters. These filters do not interfere with anything plugged into your outlets, or even the outlet on the filter. Remember, this is a filter, so some electricity must pass through the device, creating a small magnetic field. Designed for US and Canadian power distribution systems. Discount available for 8 or more. NOT a bio-energetic device. CE marked, and RoHS certified.

POWER STRIP WITH SWITCH - Option for 4 or 6 outlets

Easy Way to Switch Off Power Completely

It's no secret that every appliance with an illuminated LED (stereo, TV, oven, dishwasher, router, etc.) is never really OFF. If the 24/7 draw of "vampire power" adding to your utility bill isn't enough of a bother, those appliances are also producing (sometimes very high levels of) EMF emissions. You can pull the plug to solve this problem, but that isn't always easy, and it puts a lot of wear and tear on both the plug and outlet. This power strip converts a standard grounded outlet receptacle into either 4 or 6 grounded outlets and features a lighted on/off switch with built-in circuit breaker to protect against overloads. Flip the switch and the power to all those things which are plugged in goes completely dead. No EMF, period. Add a timer if you want it to come on and off automatically. It's also a great way to make room for Stetzer Filters. Saves money on power usage too! 4-Outlet Power Strip with Switch for stetzer filter

High Frequency Pollution Meters for Wiring

Dirty Electricity Meters

Stetzer "Microsurge" Meter

Stetzer Microsurge

Don't just take our word for it. You can now check for this pollution yourself! A special meter has been developed which can be plugged into an electrical outlet to determine the levels of EMF high-frequency pollution in your home or office both before and after using the HF EMPOR. Extremely easy to use and reliable.

This meter is designed to measure only the high frequency noise which may exist in your electrical wiring. It contains special filters which remove the normal 50/60 Hz signal for the readout.

The meter is very easy to use. Simply plug the meter into an electric outlet. The meter works equally well on standard outlets (2 prong, or 3-prong), and GFI outlets. It can also be used with surge suppressors, power strips or extension cords.

The readout of the meter gives an indication of how much high frequency noise is in the wiring at the outlet where the meter is located. The higher the readout, the more high frequency pollution. The readout is not calibrated, but is very useful for making relative (comparison) measurements.

Ideally, the readout should be as low as possible. It is generally agreed that readings should be below 50. Notice that unplugging appliances may affect the reading.

When using the meter in conjunction with the Graham-Stetzer Filters, plug the meter into the outlet first. Then add Graham-Stetzer Filters to the same outlet and nearby outlets and watch the reading decrease.

The use of a power strip to increase the number of available outlets is useful when you need multiple Graham-Stetzer Filters to reduce the reading to the desired level.

The meter is re-usable. Can be used on 50/60 Hz, 110-230V systems. Covers 10 kHz to 100 kHz. Has standard 2 prong North Amercian plug, so you will need an adapter to use it outside of N. America. Click here for full instructions.

What our customers tell us:

"This package came August 15th, way before it was due to arrive. It was wrapped in a box and the monitor was in a box. I was thrilled that it arrived so early. I have already used it around the house. There is a booklet that came with it explaining where you can buy other meters to measure electricity. There also was a sheet of paper explaining about the Microsurge meter. So far very happy with the buying and mailing experience."

Uses Frequency Weighting to Detect Dirty Electricity Trifield Meter Model TF2

This meter has many uses, but one unique aspect is that is allows you to compare frequency weighted to flat frequency response to determine how much "normal" EMF is present compared to how much "dirty electricity" is present. Here is what that means:

A frequency weighted meter gives more "weight" or more value to higher frequencies when present. The higher the frequency, the more the weight. A flat frequency meter gives equal weight to all frequencies. Imagine three different situations:

Situation A:
Only 10 mG of 60 Hz magnetic fields are present ("normal" EMF). Both flat and weighted meters report the same: 10 mG.

Situation B:
10 mG of 60 Hz magnetic fields are present, plus 1 mG of 600 Hz. Flat shows 10+1 = 11 mG. Weighted meter shows 10 + 1*600/60 = 10 + 10 = 20 mG

Situation C:
10 mG of 60 Hz magnetic fields are present, plus 0.1 mG of 60,000 Hz. Flat meter shows 10+0.1 = 10.1 mG. Weighted meter shows 10 + 0.1* 60,000/60 = 10 + 0.1*1000 = 110!

Bottom line" Trifield TF2 meter has both settings: flat and weighted. By taking both readings you can tell if dirty electricity is present because the weighted reading will be much higher than the flat reading.

Here is what else the TF2 can do:

The original Trifield meter has been around forever and it was a favorite of ours. This improved version is even better! The TriField Meter will test EMF pollution from "hot spots" in your home, office, or work environment so you can take steps for "prudent avoidance". Completely self-contained, no parts to lose. You still get 3 meters in one. Three axis for magnetic and extremely wide frequency response.

Here are some of the upgrades:

  • A very nice digital display allows for more precise measurements
  • Frequency flat and weighted measurements can be done by the same meter
  • The RF portion is 1000x more sensitive and can read frequencies up to 6GHz
  • Includes backlight and sound function
  • Shows both instantaneous and Peak readings

Gain peace of mind and confidence in knowing where this body penetrating pollution is coming from, and how powerful it is, so you can protect yourself and loved ones. Instruction sheet and 9V battery included. 1 year ltd warranty. Made in USA.

Setting Minimum Sensitivity Scale Accuracy Frequency Range
AC Magnetic: 0.1 mG 0-100 mG ±4% @50/60 Hz 40 Hz - 100 kHz

AM/FM Portable Radio


Great for Detecting Magnetic Fields and Dirty Electricity

Pocket-sized versatility and low cost meet to offer an old fashioned radio that offers AM/FM with an antenna.

That's all fine, but for our purposes, dial to a "quiet" section of the AM band and use this detector to "sniff" for sources of dirty electricity. The sound of loud static hissing and crackling is unmistakable. The pitch of the sound corresponds to the frequency of the fields present, and the loudness corresponds to the strength. Check around dimmer switches, outlets, appliances, lighting and computers. Also has a 3.5 mm mono earphone jack and telescoping antenna. Operates on 2 AA batteries (not included). NOTE: We are offering this unit as a detector for dirty electricity. May or may not work as a radio. Style may vary, current style is shown.

High Frequency Noise Suppression Kits in the News

MELROSE, Wis. -- Electrical "pollution" at the Melrose-Mindoro Elementary School at Mindoro has been making staff members ill, according to District Administrator Ron Perry. Several teachers and other staff members have complained of headaches, fatigue, facial flushing, numbness, sensitivity to lights and sound, tingling and loss of taste and smell. But since a contractor has installed electrical filters, the staffs' symptoms have gone away. "I was somewhat skeptical at first, but now I'm convinced because of what the people have said to me," Perry said.

The problem has been with RF (radio frequency) electromagnetic fields, which is out of balance and sends microwaves into the rooms, through walls, ceilings and humans. Perry explained the circumstances at the Feb. 24, 2003 Melrose-Mindoro District Board of Education meeting. Stetzer Electric of Blair had been updating some electrical wiring when they measured the RF waves in the Mindoro school with a "Fluke" meter. The meter showed that there was considerable amounts of electromagnetic wave energy in each of the rooms, especially in the computer lab, Perry said.

Workers claimed the neutral wires were too small, therefore electricity came back into the buildings to be grounded. By placing electrical filters (High Frequency Noise Suppressors) in every room, the RF waves instantly smoothed out, he said. The same has been done at Mel-Min High School and the elementary school in Melrose, although those places weren't as bad. "It takes out the 'trash' in the wires," Perry said. "Within a few days, people said they were feeling better. One person even said she could smell again."

So many buildings were constructed when electricity wasn't such a vital component in education. But since that time, computers, televisions, VCRs and numerous other electronics in schools has resulted in increased electricity usage, he said. By adding filters, the electromagnetic fields have been placed back into a harmonic balance.

"We've done a lot of good - unexpectedly," Perry said. "The good news is that we've cleaned up all our schools in the district. Probably, every school in Wisconsin should be checked." The staff knew that something was being done when the electrical contractors were at the school, but they were not sure exactly what was being done and what the results would be, he said. A few days later, staff members commented to Perry that they were feeling much better and they could feel the difference. "The results from the staff have been amazing," Perry said. Since those repairs, the word has spread and Perry has received many calls from school personnel in other parts of the state, as well as private individuals.
