That's not so good cologne..
Don't know if this is any help, but my gran had COPD and an asbestos -related chest condition , and her consultant recommended a dehumidifier .. it wasn't one of those great big industiral thingies , but I'm thinking that that may be less likely to aggravate a chest condition than damp, humid air and spores. Also worth asking at the hospital about advice re benefits etc - they may have someone in-house who can help ( again , there was a specialist nurse in the thoracic unit who helped with that kinda thing) or be able to point you in the right direction - you shouldn't be out of pocket for someone else's plumbing problems!
All the best with it!
