Vinnie Rossi LIO is a perfect solution. Regenerators will not solve your issue. Can you run a dedicated 20A line ? If so run it from opposite of panel from appliances. Good money spent. Then condition that line. Gigawatt, PIAudio Uber and Betabuss or others.
With the VR LIO no conditioning required and maybe no dedicated ilne either. However I still would install 20A line.
