Depends on the noise sources near you, and the gear's own filtering.
Looking at them, it looks like a very similar thing that goes on with series mode surge protection. Big coil in series with the load. Good idea.
It would be really interesting to compare them to Furmans with LiFT and SMP, especially the units with separate filter banks.
