It has been validated by EMF meters to lower electrical fields to healthier levels, helping users reduce exposure to dirty electricity and improve their home or office environment. ## Description NOTE: International customer are responsible for any additional customs fee if imposed by their home country's authorities. Review: OF COURSE THEY WORK! - These filters work. All you need to know is the electrical circuit grid in your walls and have a meter to measure. VERY valuable and effective product! Remember, especially in Apartment buildings, dirty electricity in walls tends to be very high, as you're sharing walls with neighbors that are double-wired. I have 14 filters in a small one bedroom apartment in LA. It took that many to get the fields down, but THEY WORK! Fields piggy back onto each other as well. Dirty electricity is the easiest, and relatively cheapest field to "control" of the 4. Unfortunately in apartment buildings in big metropolitan areas you're pretty much screwed for RF wifi. Steterizers can't help you there, but then again they do because they cut down the overall EMF level. Review: It actually works - My home is an older one with ungrounded wiring that has a lot of errors, which has sensitized me over the course of a year. An EMF Trifield has shown high magnetic and electrical fields around the outlets and anything pluged into the outlets. I bought this device along with the Greenwave brand and amazingly, the computer that has had such a high magnetic field I can't even work at it for more than an hour at a time is now showing normal healthy background levels! I am so happy to be able to use my computer and sit in my home without feeling drained. ## Features - Power Line EM Filter - Reduce Undersirable Power Line EM Radiation Levels ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B015AMEX5U | | Best Sellers Rank | #314,690 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #56 in Electromagnetic Interference Filters | | Customer Reviews | 4.1 4.1 out of 5 stars (87) | | Date First Available | September 12, 2015 | | Is Discontinued By Manufacturer | No | | Manufacturer | Graham Stetzer | | Product Dimensions | 2.25 x 1.83 x 3.83 inches; 6.56 ounces | ## Images ![Power Line Em Filter (4) - Image 1](https://m.media-amazon.com/images/I/41tKchL+DKL.jpg) ## Available Options This product comes in different **Item Package Quantity** options. ## Questions & Answers **Q: A meter will detect the change? How can I know that it’s working?** A: The meter that came with the Stetzerizer Filters did detect the change in the dirty electricity emitted from the outlet. To give you an example, I just plugged the meter into an outlet and got a EM Radiation level of 87 on the meter. When I plug the Stetzerizer Filter into the other half of the outlet, the meter drops to 19-20. On the back of the meter it has , LESS THAN 25 AS GOOD. 25-50 AVERAGE, MORE THAN 50 UNDESIRABLE. I have 8 of them in a 850 square foot condo, and it seems to have dropped the Electro Magnetic Radiation for the whole unit. **Q: Do you have one for the cable internet line - coaxial cable?, I feel this ball arm hair raising energy near the routers** A: I don't know the answer to your question. Keeping the routers a a good distance away from a computer can help, Also, you could try putting a ferrite snap-one device around the cable going from the router to the computer. You should check with an EMF consultant or bau-biologist. They should have a better idea of what one can do to reduce EMFs from cable lines. One EMF consultant who may be able to help you remotely is Chris Buonocore, Alexandria, VA, at Lifesource Environmental Solutions LLC. website thelifesourcesolution. Good luck. Northern Virginian **Q: I have problems with WiFi switches indicating current when circuit is off, probably due to 50+ transformers. Would these reduce that problem?** A: Based on your description, I'm not clear on what is causing your problems. But if the cause of the problems is the presence of high frequency transients (a.k.a. dirty electricity) then the Stetzerizers will help and remove the transients. If you have an oscilloscope or Stetzerizer Microsurge Meter then you can test the power outlets which you are using and measure the level of transients. **Q: People say i need a different emf meter to measure if these work. well how do i reduce electro/mag emf that my emf meter is reading high from wall?** A: Hello, yes that is correct you need Stetzerizer Microsure Meter (which is a mini oscilloscope) to measure levels of high frequency transients aka "dirty electricity". No other meter will test for dirty electricity. The testing procedure is the following: 1. plug Microsurge Meter in a outlet and test for results. Record or remember the results. Let's say your reading on the meter display says 250 units. 2. Use a shot extension cord with grounded strip of 3 or 4 outlet and connect it to the same outlet - keep the meter still plugged in. 3. Add on Stetzerizer filter to the strip and read your new results on the meter. Let's day now your reading is 195 units (lower than before you recorded without the filter) 4. Keep repeating step 3 (adding more filters to the strip) until your meter reading drops to 50 units or below. 5. Repeat the entire testing procedure with each outlet in a given room. NOTE: Start using Stetzerizer Filter in your bedroom first - this is where your body is suppose to rejuvenate itself during sleep. After that you should use the filters in any other room that you spend the most amount of time on a daily basis. I hope this helps.

An EMF Trifield has shown high magnetic and electrical fields around the outlets and anything pluged into the outlets.

Using 2 for most rooms/circuits does the trick. The electrical noise everywhere in our house ranged from 100+ to as high as 250mv. Ideally it should be less than 30mv in every outlet. Most outlets in our home are now reading 20 or less. There are a few tricky areas I'm still working on especially where we have a lot of electronics. I just ordered 4 more and will be adding a few to our garage. The seller is great and shipping is always quick, usually arriving early. ## Frequently Bought Together - Stetzerizer Filter - Power Line Em Filter (4) - Dirty Electricity: Electrification and the Diseases of Civilization --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/34270354-power-line-em-filter-4](https://www.desertcart.tw/products/34270354-power-line-em-filter-4) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-16*
