Power Conditioners effectiveness?

I still don't understand how there is clean or dirty A/C.

The reason you get mixed feeling on this issue is because there are many variables.

It's best to scope out your AC line for problems, if found, fix it. If nothing is found, no

fix needed. Nobody does this.

Dirty AC;

Filters in electronic equipment may be there not to filter out crud coming into them,

rather the filter is used to prevent the noise they generate from coming out and

feeding it back into the AC line.

But some of these filters are bi-directional, they may filter crud both ways. If some jack-azz

had a crappy piece of noisy gear that they plugged into their house, the noise it generates

can leak into the rest of the house. By adding these filters to common electronic devices,

you filter out the noise going out and coming into it.

The real question is audibility of the noise for your install ? Don't worry about other people's

homes and installs, yours is the only one important as the variables are different.

Why do you think that is?
I still don't understand how there is clean or dirty A/C. It seems like current is current. Maybe if the house wires are corroded or something, that may cause an issue...but then doesn't that suggest the power conditioner is only a band aid?

Just curious...you know I don't know enough to question anyone.

A basic antenna is just a piece of wire. Sort of like your mains. Anyway, long story short you have noise that is either caused the 60 Hz signal to be distorted or you have higher frequency noise that piggy backs on the line and can generate noise. Also, appliances such as Refrigerator, cell phone charger, computer, basically any electronic device can add distortion and noise into the lines.
