I suggest you go for a standard 7% De-tuned Passive Filter, which would filter any harmonics upwards of the 5th.

Also these posts to be put in commercial section (along with your other posts). here we discuss the problems do not give offers.

Your problem is too simple to discuss, the offers are what you are looking for.

Why don't you try your local yellow pages? Will you like an offer from say California?
