I go to pulmonary rehab 3 times a week because my lungs are so bad I use the life2000 non invasive vent to do the exercises which is 30 treadmill 20 nu step.  

Thank you all for your responses and suggestions.   I started using the 7% saline in the morning (at first I was having a hard time tolerating the 7% with my lungs) which is helping to thin the mucus.   I follow that with using the Aerobika and physical exercise.  I use 3% saline late afternoon again followed by the Aerobika.....this routine seems to be working.   I also use Albuterol prior to using the saline in a portable nebulizer.....which I love.   It is so easy to use.   In addition, I also take Mucinex once a day.   It is all so cumbersome but has to done.   
Because I tend to have low sodium I also take 1000 mg of sodium chloride orally (prescribed by a nephrologist) so I drink plenty of fluids each day to stay hydrated.  
I am scheduled to go to a family gathering next weekend but I am very concerned about the latest Covid Omnicron Variant of BA4 & BA5.   I amy fully vaccinated and boosted.   Has anyone gone to a family gathering within the past few weeks?
thank you

Yes 7% is strong and can cause irritation in the airways.  Some mix it with albuterol to help the irritation.  I do mine straight. I finally got the 7% saline but boy did the cost go up.  Medicare doesn't pay for that.  

I'm using 6% hypertonic saline in my nebuliser once a day in the evening.  Throughout the 20 minutes I use the Aerobika and huff cough.   In the morning, I do just the Aerobika and exercise.   I had NTM but it's gone now - nearly died - advanced etc.  misdiagnosed.   Oh ... and eventually ordered a sweat test from doctor #4.  When the head of the CF clinic fails to do even basic tests to find out the cause of the infection you know you're in trouble...     Hey, everyone here - get a sweat test!
