Should I get an air quality device even though I am renting?

I would need to get a Heating & A/C company to do it

I have been seriously thinking about getting a humidifier, then dry air quality affects myself and others more than anyone else, my skin instantly begins to get ashy looking the moment the house gas furnace turns on. My lips chap & our nose gets dry too. My nose is what is the worst, and the inside of our nose gets so dry that it bleeds. I can’t blow our nose or even touch it without it hurting. These are all indications of the indoor air conditions being too dry. The reason I have not bitten the bullet & bought a humidifier is because I am a roommate. My buddy Hannah owns the house I am renting. It is his heating component that is drying out the air quality. I guess I need a humidifier that is going to install right into the gas furnace device, and as the gas furnace turns on, moisture is introduced into the air. Also doing this, every room in the house would be a little more humid. The gas furnace would be more effective too. These type of humidifiers are quite extravagant & I could not install it myself. I would need to get a Heating & A/C company to do it. There are cheap little humidifiers that sit up & effect a single room. If there any point of getting this though? I sleep & read in our study room, but I do a lot of work in the home office & I exercise in there too, but what about the study room? I don’t think our nose would be fixed by only getting moisture in a single room. But I don’t want to buy something that Hannah would just keep.
