  • With numerous electrical devices in today's homes, noise on the electrical line becomes almost unavoidable. But this interference doesn't need to interrupt the X10 signals sent to your devices. Placing a filter between your X10 device and the noisy load blocks the noise and lets X10 signals flow. Now you can protect an entire circuit in your home: The ACT 20-Amp Low-Pass Filter is a 20-amp, hard-wired filter made to block noise from an entire circuit.

    The ACT 20-Amp Low-Pass Filter wires directly into your circuit-breaker box, so if you have one load on a particular circuit that generates interference, installing this filter can eliminate up to 97.5 percent of this problem noise with its 40-to-1 blocking ratio. In other words, if the noise or signal is at a level of 1 volt peak-to-peak, only about 25mv should leak through.

    This hard-wired noise filter is rated for 20 amps on a maximum of 277 volts.

    Got excited when reading others had fixed their X10 problems with this so I bought two for my variable speed pool pump Hayward Eco-Star. Installed in a few minutes and they simply worked. I was able to once again control my pool equipment with my X10 remote.
    My only hesitation is these things are HUGE!! I had to remove from plastic container danger...don't do this and I made my own packaging so I could install both units in my pool controller box don't do this!!.

    A little pricey and HUGE packaging... but hey, it works!

    Very happy with the two filters I bought to quiet a variable speed pool pump. Units arrived in two days! Fantastic. Thank you. Would prefer if the units could live in three gang boxes outdoors. Otherwise, they work great.

    Review of 4846

    I installed a Hayward variable speed pool pump and a Hayward salt to chlorine generator this spring. The VS pump and the transformer in the chlorine generator created a lot of noise and interference with my X-10. Everything Insteon worked, but practically nothing X-10 worked when the pump was running. So my choices were to replace all my old X-10 with Insteon, or try these filters. They worked perfectly. I am back to 100% reliability with my X-10. I needed 2 of them since my equipment is 220v, and I had to wire them phase to phase because I wanted them near the pool equipment and there was no neutral wire. (ACT tech support helped me with this) I highly recommend these, especially if you know a new piece of equipment is causing the noise. They work.
