The situation that you describe is probably interference. There are two types of interference that can cause problems with TV or radio stations. They are Radio Frequency Interference (RFI) and Line Interference (Line Noise). Radio Frequency Interference (RFI) results from radio waves created by electrical equipment. These waves radiate outward in all directions and can be picked up by household electrical wires that act as antennas. An Electronic Air Cleaner can only create enough RFI to affect a television, intercom, or a small radio when it arcs. The Federal Communications Commission regulates all products that could create RFI. All of Honeywell’s Electronic Air Cleaners conform to FCC Part 15 Class B as well as Canadian EMI Standards. If the problem is constant, and the air cleaner is not constantly arcing, then the problem is Line Interference. Line Interference (Line Noise) can occur anytime an electrical circuit is made or broken. Fluctuations in an electrical load can also cause Line Interference.
