I am reading and typing on a phone, so giving links is difficult. If you go to the main MAC and Bronchiectasis page, you can search within our group and learn a lot about airway clearance. It is important even without symptoms because our lungs cannot clear mucus normally and that is where infection breeds.
Maybe some other members like @scoop and @irene8 can offer you some suggestions.

Airway clearance, think of it like flossing your teeth, this is lung hygiene and should be part of our daily routine - forever. I am with you, pretty new to this diagnosis. After a second opinion, pulmonologist came to the same conclusion, that it’s not the time to go on antibiotics, I told him my family who are physicians are going to be dismayed that we are not going to treat. This second pulmonologist said, tell them you are treating. The precautions you are taking, and the airway clearance practices are the front line of treatment. Further, he said about 1/3 of us will remain stable, 2/3 will have disease progression. Of the 1/3, a tiny sliver of these will clear the infection spontaneously. I am exactly at a year since diagnosis by a qualified pulmonologist began. It’s been an intensive investigative year and I’m only just now finding comfort in my level of knowledge and understanding. You’ve found this great source of wonderfully moderated info share, (thank you @sueinmn !) We all wish we weren’t here but hopefulness and sharing supportive actions keep us all coming back.
