Noise Suppressor Power EMI Filter Termianl Single-Phase Line-Conditioner JREle AC 115/250V 20A CW4L2-20A-S

Every time the treadmill in our house was in use, broad-spectrum severe interference was generated that made radio reception difficult. I am a ham radio operator and radio listener and it was enough to be a show-stopper under some circumstances. The treadmill in question is a NordicTrack 2150, but the manufacturer sells these (or some variant) under many brand names. I installed this EMI filter and the problem has disappeared, with spurs now below the random noise level. Quantitatively, I'd estimate at least a 40-50dB sort of improvement on low-frequency and mid-frequency bands (e.g. AM radio).Installation was not terribly difficult.(EDIT: Modify your equipment at your own risk. I make no representations regarding the safety, or effect on agency approvals, of this modification.)Release the strain relief from the treadmill frame, then unlatch it from the existing power cable. Then re-latch the strain relief closer to the plug, so that when reinserted in the frame, there will be enough slack cable inside the frame. Find a suitable mounting spot for the filter first, so you'll know if you have enough slack. I drilled two 1/8" holes in the frame of the treadmill and used self-tapping sheet-metal screws. Then cut the cable and remove the outer jacket from both cut ends. Strip the ends of the conductors and crimp on ring terminals and you're done. Make sure that you connect the green wire of the power cord and the green wire from the treadmill frame to the ground terminal of the filter.

My new microwave tripped the AFCI/GFCI only when a small item (one cup of water) was being heated.Added this filter inside a box between the outlet and the microwave, and that fixed the problem.Have had previous good experience putting one of these in a fluorescent light ceiling fixture that was interfering with TV reception. Also worked great.

Got this for my tube guitar amp hoping to reduce some of the high frequency electrical noise. The quality looks good and it was easy to use. I didn't really hear any difference with or without the filter but it was worth a shot.

Washing machine (direct drive Samsung) when agitating, causing some cheap Chinesium LED bulbs to flicker. Some bulbs ok, others flickered. Wired a male and female cord end onto this suppressor and fed washer through it. Reduced but didn’t completely eliminate flicker. Barely noticeable now.

We added this to a whole-house intercom system and it cleaned up the connection very well. Also ran a wall-mounted CD player thru the same connector on the intercom system that was interfering, and that cleaned up even better. Very pleased. Overall, this works.

I recently replaced an old, faulty magnetic ballast in a florescent fixture in the garage with a solid state ballast. Now the garage door opener's remote range is greatly reduced (<20ft.) if the light is on. If the light with new ballast is off, the remote's range is back to normal (150+ feet). The new ballast is emitting EMI/RFI that interferes wit the door opener. I put this filter on the power-in side of the opener with no difference. I then tried an additional filter on the lamp's power supply. Again, no difference. The door opener behaves the same way with or without the filters. And it is no longer possible to buy magnetic ballasts for florescent lights, so I'm stuck with this situation - short of replacing the entire lamp fixture with an LED type. That is fairly expensive to replace the whole fixture. Maybe I will do sometime in the future. For now, these filters did nothing to improve the situation. I rated it 2 stars because it at least didn't make things worse.

Installed this on my outside led pole light. Well actually it's installed in a weather tight electrical box. I was getting bad rf interference on my lower tv channels. Put this little jewel on and cleared the lower channels right up.

Worked excellent. Put it inline with my furnace, furnace was causing my wifi mesh to reset every time it cycled on. I am pretty sure it was the ECM blower motor causing the issue.
