The way Puron has worked for most folks, is to plug it directly in the conditioner. That way it would not waste an outlet. But in my case, I have plugged it into the outlet that the conditioner is plugged into. I was anyways not using that extra outlet for any other component. And I do have 2 dedicated 20amp lines (4 outlets).
But I hope you are able to give the Puron a shot. I resisted it for the longest time. But once I tried, there was no going back.
