So far no luck...

I guess I have a very noisy circuit with a variety of devices on it, that the filter has so far had no effect in cleaning up. The result is my I/O controller is unreachable. I plan to add a WiFi extender and run another circuit to try to make the I/O connection more reliable.

Thank you for leaving your feedback on the Powerline Noise Filter. We're sorry to hear that you have not seen the desired results yet. Please contact us at as we will be more than happy to help troubleshoot the issue. We look forward to hearing from you.

These filters are essential.

I use APC Uninterruptible Power Supplies on my computers, and they put out noise over the AC line that interferes with Insteon on/off modules that I use on the same circuit. These filters work great in blocking the UPS line noise.


My apple laptop was replaced several times for charging issues. Someone suggested to get one of these things. I tried it, and no more charging issues.

Dramatic reduction in failures

I used a FilterLinc to isolate the power adapter for my Universal Devices Polisy device from the power line. My PLM is piggybacked on the pass-through (unfiltered) plug on the face of the FilterLinc.

Insteon signal failures have reduced significantly, from many per day to one or two per week. The power adapter (black unit in the photo) apparently was noisy enough to create a lot of problems.

Thank you for sharing!

Works great

I used it to isolate a mini-fridge that was absorbing signals and wreaking havoc on the line cleanliness of a circuit to my home office. No more problems!
