Advise on filter for electric motor startup current spikes

Hi all,

I hope someone can give some advise on what filter type and values to use to filter out these spikes:

In theory, the spikes are not wrong. When the fridge compressor kicks in, for a very short time it pulls 1,5kW to get going, and then drops to a stable 40-80W.
But it doesn’t look nice as you can see. It makes it messy. Which filter would be best suited to do this (without impacting the rest of the values too much)?
Thanks!
