UPS with no RF noise?

[VK3RX]

I was about to put a post up asking for solutions re RFI from a UPS, and discovered I'd posted this above last year.

Has anyone had experience with using these or similar to suppress RFI on mains leads, which seems to be where the noise is being radiated from:

U16 Ferrite Voltage Spike Protectors/Noise Suppressors
U15 Ferrite Voltage Spike Protectors/Noise Suppressors
