I have bronchiectasis and agree with many of these suggestions. Yes to fewer carpets, shades instead of drapes, washable bedding. However, would like more discussion about keeping windows open or not. We have Molecule air purifiers in our two bedroom condo, we get the best air readings when we leave the window open at night. also am currently wondering about the pluses and minuses of houseplants as I have been diagnosed with pseudonomas.
