Interstation interference

A friend and I want to operate with rigs and antenna nearby, lets say he will be on 20M and I will be on 40M.
We have experience interferences when transmitting.
My research into this, the interferences come frrom harmonics and/or phase noise.
Can a band filter for each rig connected between the rig and the antenna for each of the band operating on that rig solve this issue.
We have already tried lowering power, spacing antenna starts and at different angles, etc. Antennas are wire end fed, power is no more than 100W.
Who makes a proven product for this?

You might also look at the large Multi-Multi contest stations across the country who operate their equipment with the same RF environment two or more weekends a month. Good filter designs and careful grounding practices can get you there.
