I would be willing to risk a small bet that even loads washed in the new machine would be softer and fluffier if dried in the Filtrator, but you have to look at the economics of drying in a Filtrator. The Filtrator, while rated at less wattage per hour than a modern dryer because of its two 2200 watt heating elements, takes longer to dry than a regular air flow dryer and at much higher temperatures because it cannot condense the steam as fast as it is evaporated, but it is the steam that makes the fluffy and oh-so-soft results. The ozone contained in the almost closed system combines with the fragrance of boiled cotton, and they do dry at temperatures above the boiling point at their higher settings, to make that wonderful Filtrator Fragrance. In the winter, the heat given off by the Filtrator is welcome, as is the humidity, so you at least recover the heat you are paying for.
Any condensing combo will produce the same fluffy, soft results. We have talked about having a drying contest among the combos in the museum with each of them being loaded with an identical load spun out to a uniform degree of dampness to see how quickly they dry. Given good, cold water, most condenser combos condense faster than the Filtrator. With a water condensing dryer, however, you have to save the water it heats, which is just right for warm water washing, to get the benefit of the heat used for drying.
