Essential Info

This small unit will filter up to five amps of 120-volt electricity. Install this filter between a noisy electrical device and the AC lines. The unit, when installed close to the noise-generating device, will prevent electrical line noise pollution for the rest of the house. It is most commonly needed on High Pressure Discharge lighting (HID) and fixtures with electronic low-voltage transformers. Some fluorescent light ballast transformers can also produce noise.


What's Included

  • Leviton Noise Block 6287
  • More Info

    Use this filter with X10 receivers to fix bothersome problems. If you can turn on an X10 device remotely, but not turn it off, then this filter will help. When the device is on, (and generating noise), the X10 receiver can't "see" the X10 off signal because of the noise. When the device is off, there is no noise, so the command is easily recognized on the AC lines. Install this filter as close to the noise generator as possible. It needs to be installed between the X10 receiver and the device being controlled. Please note that the filter will NOT WORK for two wire wall switches that do not have a neutral wire. If installed on two-wire switches, it will also filter out X10 signals. See the wiring diagram on the right for more information.

    Install this unit when installing HID lighting to prevent erratic operation. High Pressure Discharge lighting (HID) often generates a significant amount of noise when turned off. The noise usually turns the X10 module back on immediately after it is turned off. If the X10 module chatters then turning on HID lighting, this filter will alleviate the problem.

    Seems to be working: the flakey X10 switch is much more reliable since installing the noise block on a new electronic ballast.

    Works the way one would expect.
    CHRISTOPHER -- pfafftown, NC   1/10/2013
    I installed this product inside the outlet that was powering an appliance that was causing noise and affecting my X10 gear. It worked perfectly and without using a wall wart for noise filtering! I'll definitely purchase more of these as the need arises.
    ROBERT -- santa cruz, CA   12/31/2012
    Fixed my low voltage noise problem and now my x10 stuff works just fine.

    I have been using 4 of those units, one each together with a keypadlinc dimmer, with the goal to improve power line communication load for each are 5 fluorescent bulbs. This has created major issues with the dimmers when they are restarted power turned back on, as they 'sense' the load. Dimmers are oscillating powering on, resetting cycle constantly. On two of the fixtures, it seemed to work OK and communication did improve but after power loss in the house, the 2 dimmers have been in this reset/on blinking state until I pulled the power latch at the bottom of the keypadlinc. I had to take them out as wife was getting very upset about those lights blinking.

    Small and compact, works perfect.
    DOUGLAS -- boulder, CO   11/16/2012
    Did the job. Brought some X10 stuff back to life after I figured out that some new Evolve Z-wave switches were sucking up the X10 signal. Putting this thing in the supply to the z-wave switches cured the problem. (By the way, I am quite happy with the z-wave switches in all other respects). Only gets 4 stars because I feel it is annoyingly expensive for what it is. (But it did the job)

    Based on the many good reviews here, I bought this filter to put on my newly installed 4 bulb T-8 flourescent lamp in my shop. The light fixture, a Home Depot purchase, puts out an amazing amount of light in my basement shop, but, unfortunately, also puts out an amazing amount of EMI - to the point I can't play my radio. I get nothing but static. The filter accomplished effectively nothing. Back to the drawing board.
    TOMMY -- lawrenceville, GA   7/19/2012
    This device works - mostly. I still have one device that does not report a status if the florescent light with the noise blocker installed is turned on. The other 5 Insteon devices are working now.
    STEVEN -- logan, OH   7/9/2012
    Solved my problem
    DAVID -- deerfield, IL   6/30/2012
    This did not seem to make any difference for me.
    ALEX -- toronto, ON   4/8/2012
    Works just the way it should with Insteon. And it is small enough to hid inside a outlet box.
    DEANE -- cupertino, CA   3/4/2012
    This solved my problem with a couple of fixtures that had 4 CFLs each. The fixtures would turn on automatically but not off. The CFLs were sucking up the signal. Installed these and problem fixed.
    KEN -- centre hall, PA   2/15/2012
    Did not reduce the RFI from a fluorescent light. Returned product.
    PHILIP -- long beach, CA   1/27/2012
    Totally solved the interference problem.
    WILLIAM -- lakeville, MN   12/17/2011
    Haven't installed it yet. Turns out I had a specific CFL lightbulb that was the culprit, so I moved it to a rarely used location. My plan however is to install this in the light fixture I moved the CFL bulb to. It should do exactly as advertised in that fixture.
    ERIC -- hoschton, GA   11/24/2011
    If you plan to mess with Insteon or x10 then you'll need a few of these.
    GERALD -- san diego, CA   9/23/2011
    I installed 2 of these units on Insteon light switches and the problem that I had communicating with these lights were greatly reduced.

    I needed this quickly and it came promptly.
