Hi Seth - Are you using a saline neb? I am convinced that it has contributed to my success in staying almost completely infection free for 20 months. (One small exacerbation this spring, treated with nebs and prednisone.) I think there are others here who are seeing similar success, such as @thumperguy.

For the past 6-7 years, before the Big 3, I was suffering 2-3 major lung infections per year, with antibiotics and months of asthma attacks. For 20 months, I have stayed healthy in spite of regular exposure to little germ factories (aka grandchildren.)

I got a rainfall (big droplet) showerhead and wear my mask and gloves faithfully around the garden. But I do not boil my water - I was again encouraged that this is not always necessary by Dr Falkinham's latest article post by Armando (@bolso1) today here:https://connect.mayoclinic.org/discussion/reducing-exposure-to-nontuberculous-mycobacteria-ntm/?pg=1#comment-636005

Here's hoping you too will be a success story for a long time!
Sue
