Briidea Dirty Electricity Filters, Reduce High-Frequency Noise Caused by Electronic Devices for a Stable and Clean Power Supply for You, Extend the Lifespan of Your Electric Device, White

I have this plugged between my Anker power strip and the wall outlet and in return. I have 12 clean outlets that I can use for my audio equipment. It works and yes I’m hearing the difference. I plugged my WiiM Ultra, FiiO Warmer R2R, FiiO K15 and EDIFIER R2750DB MKII to the Anker power strip. All getting filtered and clean energy. Try it and if you’re not satisfied or hear any difference. Then return the product.

NOT A SAFE PRODUCT!!! This electricity filter is not built well for filtering electrical noise as it is advertised. Not worth the money, don't be fooled by the size. Holds a lot of power if you unplug it do not touch the terminals or it might shock you. This product is built to be used like a UPS, but instead of using a battery, it's a capacitor. It filters some high frequency noise, and for my speakers it worked for a minute and then stopped working shortly after. I bought the product because I wanted it immediately and this one would ship the fastest. Probably because it's not worth the money. I didn't read the reviews until afterward, and I saw the one that said it shocked them after unplugged. That made me very concerned, so I tested it and it seemed to work until I walked away and came back. Once I came back the same noise I was trying to eliminate was back and so I unplugged it and took a screwdriver and held it in the neutral terminal then touched the positive terminal and a huge spark came off the device. This is not a safe product to have around the house, and doesn't even work as advertised.

I run on a treadmill while watching TV. My treadmill was causing interference. My stationary bike trainer does not have the same issue. Plugging the treadmill into this and then into a receptacle on the opposite side of the room from my TV eliminated the problem virtually always. Occasionally I still have a few horizontal lines, but I'm unsure whether it's from the electric connection or is direct EMF from the motor. This solved the problem both for Roku and computer-streamed shows.

I would not have guessed that a new SONY Bravia would create an electromagnetic 'storm' for a Heath Kit clock, which would jump five, ten, twenty minutes fast and / or slow within a few hours. Thank goodness for the internet. Within a few quick searches the answer was revealed : EMI could be (and was) the cause. After plugging the Bridea filter between the outlet and the existing devices (SONY, speakers, clock, etc), the clock settled down without a shutter and kept perfect time thereafter. The filter is functional, easy to install, noiseless and has excellent value. Peace of mind, too, if human exposure to EMI is an issue.

Product is well built but does not work to reduce or remove line noise that effects AM or FM radio reception while connected to home AC power outlets.

My application for this device was somewhat unusual. I wanted to use it on a laser printer to prevent noise from the printer getting back onto the AFCI breaker and causing a nuisance trip. It worked perfectly in doing that, so for me this is a big win. I think it very likely that it would solve similar nuisance tripping problems from other tools and appliances. For those interested, the breaker was a Square-D QO combination GFCI/AFCI with purple button. I had some concern about the power handling capability as I didn't find that important information in the product info. However, the actual device has a sticker saying the max load was 15A, which would be adequate for almost anything. My large printer draws at least 10A when printing and at startup. I did not notice this filter warming up at all. Some things to consider are the size and the claims. The device is fairly bulky so beware of that if something has to be pushed up against the wall where it is plugged in. The other thing are the claims about keeping a healthy environment, or generally being needed to improve the function of some devices such as musical instruments. All I can say about the health benefits of using this devices is that I am skeptical, and could imagine certain types of magnetic radiation being higher in the near field of this device that without. It would not concern me either way. As far as needing it to preserve the best lifetime or performance of a specific load, that is possible but only in rare cases. The great majority of people living on city power have good enough electricity and good enough appliances to where there would be no benefit. If not, then this gadget might be a fix, but only if the problem is high frequency noise. For these reasons, and the fairly high cost, I demote it by one star.

Unfortunately it did not solve the problem! I have a washing machine that causes lights to flicker in two rooms next to the utility room. I have already had an electrician to work on the issue but so far no success! I have replaced light fixtures, receptacle, tightened screws, and inspect the breaker box to our home! Yes, I replaced light bulbs also. I even replaced the washer!!!!

I was getting interference on my refrigerator temp panel from a halogen light system when it was turned on and off. I installed this filter and have not seen the problem since. It seems to do the job.

Just received two of the items today. I already have 4 x Stetzeier dirty electricity devices plus StetzeMicrosurge Meter. I compared each brand in regards to amount of reduction shown in Stetzeier Microsurge Meter. These new devices reduces equal or slightly better reduction than Stetzeier devices. I am very pleased and will keep them!
