Thanks for your reply. I am going to check into a HEPA filter. As far as the Gerd, I am on an acid reflux medication and have been for some time. It has worked very well and I have no more problems with the Gerd since on this med. It is an interesting thought though and I will ask my dr. some questions about
it. It is very hot and humid where I am right now and I know that this weather aggravates my breathing. I have also lost 40 lbs in the last year so that should help with my breathing although I never had a problem before because of weight. I will see if the mattress cleaning and all my new hypo allergenic bedding helps me. I do have central ac in my house so that keeps humidity out. I'm just not sure what more I can do. I am banning use of any aerosol products in my house. Hope some of this works. Any other suggestions would be appreciated.
