I can tell you that it was a vented model with no lint filter; large quantities of lint are expelled through the exhaust vent. It was rated not acceptable by Consumers Union. It had only one drying heat, judged too high for safe drying of some synthetics or the proper drying of wash and wear fabrics. Like the Westinghouse WD 5, the wash cycle took 45 minutes and,even though it was a vented model, the complete wash and dry program took 3 minutes longer than the condenser WD 5 to dry: 1 hr. 47 minutes versus 1 hr and 44 minutes.
