Our Verdict
This is not a humidifier. It is a replacement part for AprilAire whole-house steam systems.
You get two 4978 electrode wires and one 4004 in-line strainer for $18.23. That is a good deal for maintaining your existing setup.
The 17-inch wire length fits models 800, 800LC, 801, 865, and 866. Make sure you own one of these before buying.
You cannot use this product on its own. It plugs into an AprilAire steam humidifier tank to keep it working.
Always turn off power before installing these wires. The listing reminds you of this important safety step.
If your AprilAire electrode wires need replacing, this affordable third-party option gives you two wires plus a bonus strainer.
