Low DE dimmer switch?

Good Day,


I have a neighbor who has dimmer switches that are producing RFI that make me sick. I've tried filters at my house, to no avail.  He will let me change some of the switches to simple on/off switches, but wants to keep two of them. Are there dimmer switches that claim to by DE free (or low DE) that he could try for me?

Thank you for all that you do!

Unfortunately there are not.  You can install Stetzerizer Filters near the dimmer.  Usually there is an outlet that is on the same circuit as the dimmer switch (look at nearby outlets to see if they jump up to like 700+ when dimmer is turned on).  This would be the best thing you could do - installing filters closest to the source.  We also have some new filters coming up that may help additionally as well with some of the super high frequency stuff.

Thank you so much.  I managed to get the neighbor to let me change out three of the switches for normal on/off switches and we installed a "de-buzz" coil at the base of the light fixture which reduced the RFI significantly.  I would be very happy to hear about the newer filters you are anticipating that address the higher frequency stuff though, because I've still got the RFi from neighbors printers and chargers and modems, etc.    Thank you for taking the time to answer me.

Best always, 
Ellen

I have not heard of a "de-buzz coil" - do you have a link or name by chance?  This is interesting.

I am so sorry that I did not respond previously!   Life got crazy and it slipped through the cracks.  Here are the coils I used in neighbor's houses.
Mind you, In one house, diagonally across the street from me, the coil only worked to reduce the RFI significantly in one of the 4 fixtures we tried them in.  It did nothing to reduce the RFI in my house for the other three. They switches were all identical switches, so I don't know what made the difference.  In a second house (across the street from me and down 3 houses, the debuzz coil worked to reduce the RFI in my house significantly (by about 80%) in the one fixture we installed it in.  In every case, the electrician put the debuzz coil on the hot wire just behind the ceiling fixture that was attached to the dimmer switch.
