Hi. I have a dehumidifier plugged into the same electrical outlet as my
DSL router and wireless router. I want to electrically isolate the DSL
and wireless units from the on/off switching of the dehumidifier. The
dehumidifier has a big electric motor inside of it, and I've read that
the on/off action of that motor kicks electrical garbage backwards into
the line and can affect my electronics.

I've narrowed my choices down to either an isolation transformer:

or a line conditioner:

The models I picked out cost about the same. It looks like they cover
most of the same ground, but not being an electrician, I'm not
completely sure. Which do you recommend?

Thanks.

The isolation xformer won't help. The line conditioner will but you
want to plug your electronics into it, not the dehumidifier - this means
you can buy a much much smaller line conditioner.

But I would do two things first. 1) See if you actually have a problem.
The electronics gear is likely to do just fine without any extra gizmos.
2) See if you can run the dehumidifier from another socket or circuit in
the house.
