The ComportPro Cell is originally manufactured with one very long ionizing wire that is strung back-and-forth 10 times. The genuine ComportPro replacement ionizing wire is not a single long wire but individual short wires. This simplifies installation.
These individual wires have a length of 16-3/8 inch, the distance between the crimped ends. Ionizing wires are made of non magnetic tungsten with 0.01 inch diameter.
The price reflects a package of 1 wire.
