Wow, although correct, I hope her delivery was a little better than what you have typed out

I'm used to our doctor being a little more on the positive side. I guess she got her point across though because there was no mensing words
I get what she was saying -- your efforts would be better spent on treating his CF symptoms, not trying to scrub your house clean

And, yes, you need to concentrate on treating his problems now, rather than sitting on your hands hoping for the cure to come.... but I don't think that's what you were asking to do! Anyway, she is correct, they are having problems with the delivery of the DNA, but our doctor is still very excited about the prospect of it working at some point. And, as a side note, so far, if they do get it to work, it will only work on gene mutations that end with an X
She is also correct about air purifiers not getting rid of <b>bacteria</b> (I don't think anyone here suggested they did) but they are generally helpful in other ways by making the air "cleaner", easier for people with asthma or allergies to tolerate because a good HEPA filter <b>will</b> remove mold & pollen spores, dust mites & pet dander. In my book, anything that removes potential irritants to the lungs, would be a good thing for a person with CF to have around.
