KFL3A-400 Elecraft 400Hz 8-Pole Roofing Filter for K3 Transceiver.

 This is the most popular CW filter for use with the K3. It is a steep sided 8-pole filter that provides a fine balance between selectivity and tuning around a narrow band sector.

They can also be manually selected from a simple button press from the front panel,
