That's not a bad idea; most UPSes have MOVs in them, and some have
decent line filters. Cheap consumer-grade ones typically don't, but
those should be in the garbage anyway.
A note about MOVs: I generally like MOVs, but they do have one evil
aspect: They fail silently, and you won't know that they're no longer
doing their jobs.

The UPSes? Many higher-end UPSes from even 20 years ago have serial
ports for monitoring.
