I completely eliminated blower noise from my new Bryant furnace with type 31 snap on ferrite beads on the control lines. Two 1/2 inch beads on each line with 3 turns through each bead as close to the cabinet exit as possible. Took the noise from S7 to my usual -125 dBm band noise level. No need for a line filter.
