I am designing a low pass filter to be used in conjunction with some metal oxide varistor's in order to create a sort of power conditioner.

It is to be passive in nature, and run off of standard 120V 60Hz source. I am having trouble figuring out how to determine the values of the parts required.

I would like to use either a 'pi' or 'T' type filter.

If anyone could provide some help on how to go about this, it would be greatly appreciated.

Now here is what I know:

I am going to use 3 220V rated MOV's for preventing voltage spikes.
I would like this filter to be passive in nature.
This is for the purpose of attaching electronics like TV's, computers, etc.
It should also be able to handle a 3/4 HP motor.

The point of the filter is to eliminate 'noise' on the lines when inductive or capacitive loads are attached.
