This replacement power cord extends from the transformer (power supply) to the wall outlet. It does not include a transformer (power supply) to the unit's connection. Please refer to the original Owner's Manual for instructions.
The green indicator light on the transformer will be lit if the unit is plugged into the wall outlet. If the light isn't lit on the transformer but the unit is still working, the cord is working properly.
Compatible with pureAir 3000 and GT3000 Whole-Home Air Purifiers.
