My grandfather has emphysema and I know there are environmental ways too help. What are they?

My grandfather is in his 80s and has emphysema ( I think from being around absestos). We have air filters and central A/C and try to reduce his exposure to odors. The main problem is my grandmother. She insists on hanging out sheets and vacuuming while he's in the room. She also uses this 30 year old vacuum and refuses to try one with a HEPA. She says hers was the best on the market when she bought it. It throws tons of dust into the air. She doesn't wear perfume and she's very aware of when he's using his inhalers (he also has asthma). She just doesn't seem to get the fact that some things are out there that can help her help him breathe better. They see several different doctors so none of them know everything about what happens at home. I was wondering if anyone has had a similar experience AND what they did. Also if anyone knows of websites or sources that are really good maybe proof would knock some sense into her. She's a wonderful woman just very old school.

He obviously leaves the room when my Gramma is vaccuming. I'm just worried about what's still in the air hours later. I know I have read things such as don't hang wash out and use air purifiers etc. They avoid environments were people smoke (such as only going to smoke free restuarants and not going to the homes of persons who smoke). He also uses the masks a lot when he's out doors. He loves sitting on the porch and often will wear them at home. My gramma is stubborn and I guess I was just looking for specific websites that reiterate the cleaning things so I have something specific to show her. She's old school and doesn't believe word of mouth stuff that she didn't grow up with. But if I can show her specific ressearch or even just websites or newspaper articles she's more likely to believe it. Unfortunately, saying "some guy on the internet said" won't cut it with her. I really do appreciate everyone's responses. And I wish good health on you who are suffering as well.

Before there were vacuums there was and for me still is the damp mop with a sprinkling of disinfectant for picking up all the dust .Then theres the dusting above the floor again damp cloth,then all the polishing of both floors and above.
Emphysema to me, also with others that Ive spoken to seems to have an attachment of anxiety when dust is seen flying our way and it does hurt its a burning sensation in your throat and chest.I have just find out why one of my old friends with Emphy whose 86yo/ but his lung is only 70 still likes a beer or two.It truly helps them to relax so much that they're breathing like a normal person for a while under the influence, and I think good on you live.I am 57yo/ with a lung of a 90 yo/ . So each time we meet at the Hospital classes and we're called together we have a good laugh in finding out if we all have the same age lungs.Look after your Grandad and mention to Nan that she will have no one to clean for soon.Ask if she could go back to the real old school, mops etc washing ceilings,walls then to polish. Every day

i feel sorry but all pray for him sorry uhh u should buy a new vacuum

Some things that can really cause problems with people who have lung disease..
Smoking around them ( duh )
Perfumes
Air Freshners
Carpet fresh powders
Bleach
Basicly any strong scented things like that..
My Sister passed away from terminal lung disease and anything like that would give her problems..

Her Doctor suggested she wear those paper masks.. they are made for painters. she wore these a lot..if we would go to a restaraunt where there was smoking , when we would vacuum etc..

She kept those and also hand sanitizer in her purse at all times when she was still able to go out.. the hand sanitizer is great to have for him because people with lung disease are to avoid getting sick as best as possible.. hence the mask and hand sanitizer were a great help.. any infection or cold or flu in the lungs can be fatal for a person with lung disease..

I would suggest the mask for when your gma vacuums and he should leave the room as well..the mask will keep dust particles that fly around from going up his nose or in his mouth.. its a great help
