Boyfriend nuts about clean indoor air quality

My boyfriend has asthma that he thinks is severe and I think it is all in his head.

When he was a kid he was overweight and wanted to play sports.

He had trouble keeping up with the other kids and had no stamina. Since he was panting and breathing a lot, he went to the doctor and got an inhaler. Even since then he is convinced his asthma is life threatening. His is insane about keeping the house super clean and the indoor air quality fresh. We have everything you can think of to improve indoor air. Our heating device has a humidifier to add moisture in the air during the dry winter season. A dehumidifier works with the AC to prevent mold growth in the house and inside the AC machine. We also have an air purification device that hooks into our HVAC and works all year around. The air purifier is meant to remove dust, hair and odors from the air quality. We even have UV lights providing double duty on these jobs too. The final step my boyfriend takes is yearly ductwork cleaning. Once every seven years the ductwork needs to be cleaned. In that time hair, dirt and debris will get in the air vent and ruin the air quality. Once a year my boyfriend has the HVAC and connecting ductwork taken care of. I guess there are worse things. It is just really expensive and I know we don’t really need to do it. But I don’t dare mention it since my boyfriend thinks he might die if the ducts are dirty.
