@sherrig thanks so much for the info. I did read on the Bronchiectasis & NTM chats, that the Safe Water filters need to be used at lower temps. For me that is a real negative . . If I change anything , it needs to be for a high, wall mounted shower head. Placing a filter directly above my shower head would work best with my current plumbing .

* However…I had 2 separate test results of 1+ MAC cultures in the past 6 months, but I just received a culture back yesterday that didn’t show any MAC. Nothing in my water systems has changed during this time frame, so I guess I’m going to hold off for now on making any big changes .
I was at UT Tyler yesterday , and the pulmonologist said it’s possible the MAC may not come back . She is also in the camp that believes you can make all the changes and still get MAC, and visa versa. I was getting concerned with the positive MAC cultures and considering making some changes . If MAC starts rearing its head again , I may rethink it all and add a filter . My hubs checked and our hot water heater is a little above 130, so I guess I’ll see how things continue to work out , and continue to have sputum checks .
Thanks again!
